The heart of any electronics design is the components. The component that you ultimately solder onto the board needs to be represented, or modeled, in each design domain as a symbol on the schematic, as a SPICE model in the simulator, as a footprint on the board, and as a 3D STEP model in the file you hand off to the mechanical designer.

Altium Designer's Components panel provides a powerful interface that you can use to interact with all your components - both Workspace and non-Workspace. You can search for the required component by specifying the category and using straightforward search mode by entering a query (a full or partial component name, value, etc.) in the search field. Additionally, the panel provides a filter-based parametric (faceted) search capability for specifying target component parameters for your Workspace components. The panel also offers options to edit a Workspace component through the Component Editor in its Single Component Editing mode , view the component in its source Workspace, and perform component management functions such as component creation and cloning or editing the selected component's Part Choices and Type. A component can be placed on the schematic by dragging it or using the Place command from the component's right-click menu.
And while you can, of course, create your own components, Altium Designer provides a powerful Manufacturer Part Search panel that can be used to search for real-world manufactured parts. If you have a Workspace, you can save those parts in that Workspace and then access them through the Components panel. This process involves creating a new Workspace component - using the Component Editor in its Single Component Editing mode - and saving to your Workspace.
The Components panel provides direct access to available Workspace components and database and file-based library components in Altium Designer.
The panel sources components from a connected Workspace and any open or installed libraries. The panel offers full details of the selected component (Parameters, Models, Part Choices, Supplier data, etc.), component comparison, and for Workspace components, a filter-based parametric search capability for specifying target component parameters.

The Components panel in its normal mode
The Components panel in its compact mode
The Components panel uses the basic search engine functionality and view that is applied in the Manufacturer Part Search panel . While the Manufacturer Part Search panel harnesses the Altium Parts Provider service and focuses on the component manufacturer and supplier data searches, the Components panel is populated with ready-to-place components from your connected Workspace and database and file-based library sources.
For Workspace components, only the latest revision of each component is presented in the panel.
While much of the functionality for working with components is available through the
Components panel, you can also use the
Explorer panel – essentially the former provides a subset of the functionality available through the latter, and focused with respect to component management. There will be some features relating to components themselves that can still only be performed through the
Explorer panel (adding datasheets without editing, changing states, deletion of components and models en masse, etc), but these would be more for atypical, edge cases, or as part of administration/Workspace structuring activities. Remember that the component is just one content type – the
Explorer panel comes into its own for the entire gamut of content types supported by a Workspace. For example, the creation and management of component templates – very much a relevant entity for components – can be carried out only from within the
Explorer panel (unless templates are created at the time of library import using the
Library Importer ).
Components Panel Access
To open the Components panel, select View » Panels » Components from the main menus or the Components option from the
From within a schematic document, use the P, P keyboard shortcut to open the Components panel. You can also use the Place » Part command from the main menus, the Place » Part command from the right-click menu of the schematic editor design space, or the Part button (Active Bar .
From within a PCB document, use the P, C keyboard shortcut to open the Components panel. You can also use the Place » Component command from the main menus, the Place » Component command from the right-click menu of the PCB editor design space, or the Component command (Active Bar .
At the first launch of the Components panel in the current Altium Designer session, the following controls are available when connected to a Workspace:
Use Existing Components – click to browse the component type currently selected in the panel's top drop-down.
Delete Existing Components – click to open the Delete Existing Components dialog followed by the Data Cleanup page of your Workspace's Settings where you can select the content types to be removed.
Import Library – click to open the standard Windows Open dialog then select a database or file-based library saved on your local or network folder. After opening a library file, the Library Importer in its Simple mode will launch with the selected library loaded.
Create Component – click to open the Create New Component dialog followed by the Component Editor in Single Component Editing mode ready to define a new component.
The panel’s Categories pane (or the drop-down menu in compact mode) lists all available Workspace components under the All category entry and any available libraries. When the panel is in its normal mode, click the Categories list icon « icon to collapse or expand the display of the column and use the Details pane. When sifting through the Categories pane, the Up/Down and PgUp/PgDn keyboard shortcuts may be used to walk through the list. The Left/Right keyboard shortcuts may be used to open and close the individual branches.
The Categories grouping for Workspace components is derived from the Component Type parameters associated with each component. For example, if the Component Type for a component has been specified as Resistor, then that component will be listed under the Resistor category in the Components panel (regardless of the workspace folder it resides in).
To specify or change a component's type
on-the-fly , right-click on its entry then select the
Operations » Change Component Type option from the context menu to open the
Choose component type dialog .
A component's Type parameter is established:
Component Types are managed (created/edited/removed) on the Data Management – Component Types page of the Preferences dialog. The dialog's Templates button opens the Edit Templates dialog, where the Component Template associated with each Component Type can be specified or changed.
NOTE: The Category a component is listed under is defined by its Component Type parameter, and is not related to the Workspace folder it resides in. Therefore, if you move a component to a different folder through the Explorer panel , such a change will not be reflected in the Components panel.
Operations Menu
The operations menu options provide you the ability to set file-based libraries preferences, perform searches, and specify if component models collection is visible. To access these options, select the operations menu

Best Fit – merges the contents from the Name and Descriptions columns together so they are closely placed, with no excess room between each column.
Best Fit All Columns – merges the contents from all columns together so they are closely placed, with no excess room between each column.
Clear Sorting – used to undo the sorting of columns.
Enable Columns Grouping – allows you to drag column headers by a specific column, allowing you to change the order of the Name , Description , and Footprint columns.
Select Columns – opens the Select Columns dialog, which allows you to select other columns you would like visible in this section.
Apply Column Visibility to Child Categories – in cases when the selected category has a child category, use this command to ensure the possibility of pushing column visibility settings from parent categories to child categories. This command is available only when a child category exists.
Component Search and Functions
Searching for Components
To search for available components in the Components panel, enter a phrase in the Search field and/or use the panel's Categories and Filters selections to narrow the component listing to your specific needs. Filters are supported for Workspace components only, and as in the Manufacturer Part Search panel , the Components panel supports unit-aware (text to number) search filters. The search functionality prioritizes results according to the entered search criteria.
The Search function allows you to select then edit or add to an active Search string.
Click the 'active' search string to enter it into the Search field. You can reuse or edit that search from the Search field.
The Search field also supports searching with wildcards, denoted by an asterisk (*) in the string.
Find Similar Components dialog accessed by right-clicking on a listed component, then selecting Find Similar Components , provides the possibility to define search preferences based on the selected component.
The final search results will depend on the selected component type, be it Workspace or non-Workspace components, and your Workspace connection status. For example, Workspace components will often display more parameters than a non-Workspace component. To specifically gather components and parameters that are the same or different from the one selected, the drop-downs may be utilized to select Same , Any , or Different choices.
Options and Controls of the Find Similar Components Dialog
The dialog is divided into three primary sections that list the attributes of the chosen component, sectioned off by Component , Parameters , and Models.
Use the Apply button to test and fine tune search criteria to yield the desired results without closing the dialog.
Attribute Grid
The data displayed in this region will depend upon the component that was clicked on while accessing the dialog.
The grid of attributes for the chosen component is divided into three columns:
Left Column - lists the names of all the attributes of the chosen component.
Center Column - lists the value of those attributes taken from the chosen component.
To search for components with different values, enter the search pattern into the attribute value column directly; the '*' character can be used as a wildcard for finding any group of characters. For example, C* will find C1 , C2 , C20 , C397 , Cap5 , etc. Edits made to the attribute value in the dialog will not alter the attributes of the reference component.
Right Column - provides a drop-down list of options used for specifying how the associated attribute should be used to find similar components. The options are:
Any - find similar components with any value for this attribute.
Same - find similar components with the same value set for this attribute as that of the chosen component.
Different - find similar components with a different value set for this attribute as that of the chosen component.
Additional Controls
Placing Components
A selected component is placed on a schematic by dragging and dropping, selecting Place from its right-click context menu, using the Details pane, double-clicking on the entry for the required component, or using the Enter hotkey.
To place a component from the panel, you can:
Click the Place button in the Component Details pane – the cursor automatically moves to be within the bounds of the schematic sheet and the component appears floating on the cursor; position it and click to place. After placing a component, another instance of the same component will appear on the cursor; right-click to drop out of placement mode.
Right-click on the component and select Place from the context menu. The component appears floating on the cursor; position it and click to place. Note that if the panel is floating over the design space, it will fade to allow you to see the schematic and place the component. After placing a component, another instance of the same component will appear on the cursor; right-click to drop out of placement mode.
Click, Hold&Drag – click and drag the component from the grid region of the panel onto a schematic sheet. This mode requires that the cursor is held down; the component is placed when the cursor is released. After placing the component, you are free to select another component or another command.
Drag & drop places a single instance of the component. If you need to place multiple instances, use the Place command/button, or double-click on the component entry.
Placing a component truly is simplicity itself. But before you do anything, first ensure that the schematic sheet (or PCB document) that is to receive the component is open in Altium Designer and is the active document. If documents are open across multiple windows, ensure also that the window containing that active schematic document has focus.
When working with Altium Designer across multiple windows, if the Components panel or Explorer panel are docked in any mode to a window without the target schematic in it, the Place command will remain grayed-out. This is because clicking within a docked panel focuses the window to which that panel is attached. With the panel floating, however, the required Altium window can be focused (the one with the active target schematic), and that window will keep focus when working inside the panel.
Placing a Multi-part Component
If the component being placed has multiple parts, the part selected under the symbol preview image in the Models region of the panel will be initially placed.
Part drop-down in the Properties panel when the part is selected, or it can be switched to the next available part using Edit » Increment Part Number command from the main menus or the Part Actions » Increment Part Number command from the part's right-click menu.
Altium Designer supports presenting a multi-part component as either a single symbol (all sub-parts) or multiple symbols (one for each individual sub-part) using only a single component through defined Normal and Alternate display modes (
If a multi-part component has empty sub-parts in its display mode (normal or alternate), these sub-parts are omitted during placement (
If a multi-part component only has primitives defined in one sub-part, the designator suffix is hidden when that sub-part is placed on a schematic sheet (
When a sub-part has no primitives for the currently selected display mode or a display mode has no primitives for the currently selected sub-part, the corresponding entry in the Part of Mode drop-down in the component's Properties panel is grayed out (
An Unused sub-part in component violation will not occur when running a design validation if a component has sub-parts without primitives and these sub-parts are not placed on the schematic.
Filtering Through Components
When viewing Workspace components, the Filters pane is populated by selected filter options based on the current search and available parameters. Parametric filtering of the listed components provides further options for locating a specific component or type of component. Open the Filters pane from the Categories pane. In the panel's compact mode, click the Filters as a panel extension.
Note that filters are only supported for Workspace components . Use the Filter Search field within the pane to find a specific parameter filter.
❯ ❮

Javascript ID: Pnl_Components_Filter
The parametric search capability of the panel's Filters relies on suitable component parameter data being passed from the Workspace that hosts the Workspace components. As a result, the Filter functionality may be disabled when the software is connected to an older Altium server product. To enable the Filter for previous server versions, enable the ComponentSearch.LegacyAFS.Filters option in the Advanced Settings dialog .
Note that for a parameter to appear in the Filters pane, at least two different values for that parameter must be used by components in the selected category. Also, note that only a maximum of 100 of the most popular parameters (those used by more components in the connected Workspace, across all component types) are shown in the Filters pane. The following parameters (or those starting with the following names) are always shown at the top of the pane: Power, Value, Resistance, Res, Capacitance, Case, Package, Tolerance, RoHS, Lead.
The panel Filters options can be tailored to your needs by selecting particular parameter types as Favorites , which then shift to the top of the list for the current component Category. Hover to the right of a parameter filter’s name and click the
For Workspace components, the right-click menu offers options to edit the component through the Component Editor (Edit ) and perform component management functions such as component creation and cloning, or editing the selected component's Part Choices and Type (Operations ).
Additional information options in the component Details pane include: viewing a model image, viewing online datasheets (References ), live Supplier information (Part Choices ), seeing where the part has been used in Workspace projects and Managed Sheets (Where Used ), and through the right-click menu, the ability to copy selected or all component parameter data (technical details) in a tab-delimited format, and resetting parameters marked as favorites to the five default parameters.
When browsing the components in a connected Altium 365 Workspace and if any issues regarding the health of the selected component are found, an indication of it will be presented by the Component issues line above the component parameter list. The number at the right of the icon indicates the number of found issues. Click the down arrow at the right of the number to see the short descriptions of the issues.
An example of library health issues found.
Your Workspace library health can be explored in more detail through the Library Health dashboard page accessible from the Altium 365 Workspace browser interface. See Library Health Dashboard to learn more.
You can use the custom filtering feature to further refine filtering in the Components panel.
The feature is available by:
clicking the filter (
which supports filtering by selecting a Filter Value (the default), or by configuring a user-defined Filter Rule . If you select a value from the list, it is automatically converted into an expression (which can then be edited).
If you select Filter Rules to define your own filter, you then choose an operator from the first dropdown,
then either select or enter a filter value in the second dropdown.
The current filter is displayed below the result list, click the Filter Editor dialog and edit your filter.
Select a Workspace component in the Components panel to view information about where the latest revision of it is currently used in the Where Used region. The region provides quick-filter information for:
Projects – the Workspace projects in which the component has been used. Information is only presented once the project has been saved to the Workspace.
Managed Sheets – the managed schematic sheets on which the component has been used.
Reuse Blocks - the Reuse Blocks stored as part of a connected Workspace's library.
Note that the tabs will only be displayed if an entity exists in the Workspace that uses the selected component.
If a component placed from an Altium 365 Workspace is used not in all design variants of a Workspace project, the project's entry in the Where Used region will show the number of variants in which the component is used and the total number of variants for this projects, as well as the list of variants in which the component is used (
Component Data Caching
When using the Components panel, the data for Workspace components are cached to the local machine from the Workspace. This provides an offline access mode for Workspace components when Altium Designer is not connected to the Workspace, and therefore allows normal component browsing and placement, etc.
At the first launch of the Components panel in the current Altium Designer session, a warning will be shown in the panel when in offline mode, along with controls to keep using the cached component data or to clear the cache.
Click the Use Cached Data to use the cached components. This condition will be indicated by the Offline mode – cached data is being used warning text in the lower bar of the panel’s component list pane. Note that Filters are not enabled in this mode.
The cache builds up component data over time and may be cleared at any time (for all Workspaces) using the Clear Cache option that is available under Known Servers in the Data Management – Servers page of the Preferences dialog.
Caching behavior will only present cached components from the currently connected Workspace(s), such as
Altium 365 Workspace , meaning certain cached data may be disabled. This behavior may be managed from the
Data Management – Servers page of the
Preferences dialog.
Part Choices List
Edit the Part Choices List associated with a Workspace component by selecting the Operations » Create/Edit Part Choices option from the entry’s right-click menu.
Use the following Edit Part Choices dialog’s Add Part Choices dialog, which will automatically search for part manufacturers by the selected component's Name parameter. Deselect the predefined search term to manually search for alternatives. Functionally, the dialog is a modal version of the Manufacturer Part Search panel .
Part Choice list can be ranked by selecting an appropriate star icon level, where the list will automatically be reordered with the highest-ranked manufacturer choice at the top.
Part Choices are carried with the component wherever its data is applied, such as in a Schematic design, BOM document, Output Report, and so on.
When a component is selected in the Components panel, its part choice list can be seen in the Part Choices region of the Details pane. Base information (stock, median unit price, and manufacturer lifecycle) on the related part choice is also available at the top of the Details pane. The associated colored stripe indicates the fundamental suitability of the part for use based on its deduced Lifecycle state – for example, a component flagged as Obsolete (red) is not recommended over one rated for Volume Production (green). Hover over a colored stripe to see its Manufacturer Lifecycle state.
If you use the SiliconExpert or Z2Data integration functionality, additional data and controls may be available at the top of the Details pane. Refer to the Pulling Part Data from SiliconExpert and Pulling Part Data from Z2Data pages to learn more.
If you have the
Part Choice Revision Control feature enabled for your Workspace, selecting the
Operations » Create/Edit Part Choices option will open the Component Editor (in its
Single Component Editing or
Batch Component Editing mode) instead of the
Edit Part Choices dialog. Apply any required changes to the part choices and save the component(s) back to the Workspace into the next component revision(s).

The ability to edit a footprint is made available when accessing the Components , as long as valid and linked footprints are already present.
Component Selection Dialogs
The search engine and view used in the Components panel is also applied in other Altium Designer applications where a component choice is made. The component search functionality is included in these (modal) dialogs, along with an OK confirmation button and minor variations in the available action commands. The dialog is typically called Component Search .
Accessing and Placing Generic Components
This feature is in Open Beta and available when the ComponentSearch.GenericComponents option is enabled in the Advanced Settings dialog .
To expedite the process of laying out the early stages of a design, the concept of standard, basic Generic Components is available. Generic components can quickly be placed in a design without the need to find and choose a specific manufacturer part from the available component sources. Generic components are intended as placeholders that are easily replaced by a suitable component later in the design process – they also can be considered as virtual or parametric components.
To learn more about generic component creation, refer to the Creating Generic Components page.
When Altium Designer is connected to a Workspace , the available Generic Components can be accessed from the panel where they are exposed when the All option is selected in the Categories pane – or from the top drop-down menu when the panel is in its compact mode. Click on the Components panel will open that component type category in the panel.
Placing a generic component from the Components panel
Select a placed Generic Component to access its properties in the Properties panel , which provides only those settings and parameters that are relevant to this type of component. The available parameters are determined by the related Component Template (Resistors in the example shown here). Parameter values can be manually entered, or selected from a drop-down menu list that offers values sourced from all the available components of that type.

Support for Jumper Components
Jumpers, also referred to as wire links, allow you to replace routing with a Jumper component, which is often an essential ingredient to successfully designing a single-sided board. Altium Designer supports use of jumper components through a special component type of Jumper.
While you can start by placing the Jumper footprints directly onto the PCB, a suggested workflow starts at the schematic. To learn more, refer to the Working with Jumper Components page.
