The part's schematic

Hello Pavcool

Thanks for reaching us and for reporting this issue. We are going to investigate it, and we will get back to you as soon as we have an update.

Have a nice day.

Hello Pavcool

Thank you for your patience while we reviewed your feedback. :)

When this model was created in 2023, the manufacturer document we referenced did not show the data pins connected, so the footprint was built accordingly based on the pin assignment table on page 6:

Since then, we have confirmed an updated datasheet that includes the data pins and we have updated the model to match this document:

Please download the updated model from the part page again and use it in your design.

Thank you again for raising this and helping us update this model for the entire community. If you have any other questions or concerns, feel free to reach out anytime. We are always happy to help.

Thank you but I think there is still a problem.

I do not believe the origin (centroid) is computed correctly, leading to incorrect positioning for placement on a PCB.

thank you

Hello Pavcool

Thank you for reaching out and for your patience while we reviewed your feedback. :)

Previously, the origin was placed on the lower slots. We have now updated it to the center of the body outline to make placement easier and more consistent.

Please feel free to download the updated 2D and 3D models from the part page and use them in your design. If you have any other concerns or feedback, just let us know and we will be happy to help.

Happy designing!

Hello Amina,

I do not believe that the part's origin is correct.

The fabrication company I am using, jlcpcb, expects the origin to be at the *centroid* of the *copper*, not at the center of the component outline.

It was necessary for me to move the origin by about 1.352mm.

I submitted my design yesterday and my modified location was correct, at least for jlcpcb. I suspect that other fabricators will want the origin in the same place.

I want to note that I had the same problem with parts 52271-0679 and 54104-4031, although I am not sure that I downloaded these from SnapEDA, so you may want to check these.

Thank you for your help

Hello Pavcool

Thank you for taking the time to share this and for explaining your experience so clearly.

In our libraries, the default origin is typically set at the component body center, since manufacturer datasheets and IPC guidance generally reference footprints from a stable mechanical datum. This keeps the symbol, footprint and 3D model aligned and consistent even when copper features such as thermal pads or via arrays change, and it supports reuse across different EDA tools and assembly workflows.

In practice, most assembly houses can work with a body centered origin, either by referencing the mechanical center or by calculating centroids from the footprint data. That said, some processes may require a copper centroid. In those cases, your adjustment is appropriate for accurate placement, and we are glad to hear your submitted design was successful with the modified origin.

Thank you again for the thoughtful feedback. Please feel free to reach out if you have any follow up questions. We are happy to help.

Best Regards
