Recently we began adding the ability to download footprints, symbols and 3D CAD models for many of our parts. On these parts you will see a section under Documents and media for EDA/CAD Models. Formats for download include Altium, Cadence, Eagle, KiCAD, Mentor, Pulsonix, Quadcept, Zuken and 3D STEP Model.
On the models that have these downloads available you will see an EDA/CAD link to click under Documents and Media.
Here is an example of this process for a part with the Ultra Librarian Link.
This will take you to the Ultra Librarian for Digi-Key page.
Here you can review your part selection. In this example I am looking at DK part 497-3907-1-ND
