SamacSys are the world’s leading provider of ECAD models to the electronics industry.

Our mission was to solve the decades-old problem of free access to high quality PCB library content for every component and every engineer, forever!

Our guiding principles:

  • Make library content free for every engineer, globally
  • Libraries must be 100% trustworthy and therefore of the highest quality
  • Library content must be integrated with all leading PCB design tools

You can also visit our Website:


Use the Search feature, to search for any Component. Just enter the MPN, parts of the product name or anything that identifies a component.

The list shows all matching components in our Library. Just tap on any component to see the details. On the details page, you can:

  • Compare Prices
  • Add the component to your library
  • See the Datasheet
  • Display Symbol and Pinout
  • Display the Footprint of the Component
  • See the 3D Model of the Component
  • Export the Model to your prefered CAD Software


Use the Library to store components for later reference. You can add new Components to the Library using the Search function and the “Add to Library” button on the component detail page.

To remove components from your Library, just tap and hold to enable the Edit mode. Next, tap on the red (x) at the top of the component to delete it.


Models can be exported to be used in your favorite CAD Program.

For this, you will have our LibraryLoader software installed on your PC.

Exporting ECAD Models is possible in three different ways.

Export via E-Mail will generate an E-Mail with the Library file attached.
