Setting Up Your PartQuest Profile

The following sections contain information on how to set up your PartQuest profile and configure download settings.

Selecting Desktop Integration

There are two methods for downloading your parts for use in your preferred PCB design tool: Dropbox and direct download.


Dropbox is a free file hosting service that offers cloud storage that is accessible through their website or through a downloadable desktop application. Your Dropbox login allows PartQuest to access your Dropbox account in order to make an encrypted transfer of the items from your PartQuest search to Dropbox so that your parts show up in a directory on your workstation. Using the desktop application will allow you to conveniently access your PartQuest library from Designer Schematic and Designer Layout.

Once you have synced with your Dropbox account, PartQuest will create a folder in your Dropbox (found in the Apps subdirectory) called "PartQuest."

Direct Download

The direct download setting will allow you to download your parts through the browser as a .pqz archive file. Before using direct download, you will need to download the PartQuest integration utility

 Select Product Workflow

Select the Workflow for the product you are using.  Options are below include other Mentor products.  Digi-Key only sells PADS Maker.

  • Xpedition
  • PADS Pro
  • PADS Netlist
  • PADS Integrated
  • PADS Maker

Selecting the workflow will download utilities to your computer.  This may take up to 5 minutes so please wait before downloading your first part. 

Editing Property Maps

If you need to map Digi-Key property names to names that you define, you can use the Properties Mapping feature to have PartQuest automatically map your parts' property names to what they need to be upon download.  The mapping applies to data loaded into xDX Databook and to the property names included in the symbol files.

To set up property mapping, go to your profile page and find the Properties Mapping section. Provided that you have selected your desktop integration method and selected a design flow, you should have access to the Edit Property Map button.

Clicking this button will activate the menu shown below.

Select Add New Property Map, fill in the mapping information, and click Done.

Repeat the process for subsequent properties. You can edit and delete the properties you have mapped using the Edit and Delete buttons shown above.

By default, the mapping applies to all partitions.  If you change a mapping to a specific partition, then only parts you send to that partition will use the defined mapping.  Note that a mapping for a specific partition will override a mapping for “All Partitions” of the same Digi-Key property name.

Searching for Parts

After clicking Done, the filters you have applied will appear in the left sidebar under Filters.
