Creating and Editing a Custom Part

PartQuest Portal Subscription: Essential or Professional

If the PartQuest Portal search does not return any search results from the Digi-Key® component catalog for the part number or keyword you specified, then you can create a custom part.

The application generates a part based on the manufacturer name, part number, and part category you specify.

The My Created Parts page lists all the custom parts you have created and displays part information.

You may associate a symbol and footprint with a custom part and then download the part data.
