Why are origins different?

Hello, John! Thank you for contacting us.

Some manufacturers define Pin 1 placement differently, so standards may differ when the placement is confirmed by them. In this case, we have updated the 3D model to match the confirmed footprint, and you can now download and use the revised content in your designs.

If you require any further assistance, please do not hesitate to reach out. We’re here to help!

This isn't a 3D problem. It is an origin location issue. You say some manufactures define pin 1 placement differently. This is the same manufacturer. Whomever build the parts chose two different origins. They were not consistent. When one is replaced with the other, connections are no longer made. Either pin 1 ends up in the center of the other part or the center of the part ends up on pin 1.

By the way, the packages are slightly different so the cannot have the same 3D model.

Hello, John,

You are correct regarding the different locations; however, at this time, we do not have control over the centering of 3D models done outside of our Standards, as those are submitted by our community. We provide consistent footprint centering across a manufacturer when these standards are set, and we are actively working on a solution to automatically center 3D models in the future.

Additionally, the RKE-0505S/H and RYK-053.3S/H are indeed different in both size and pin configuration. You can check the dimensions in our viewer on each part page.

Please let us know if you have any other questions, we're here to help!

You say you do the footprints. So why are the origins different between the footprints? I fixed the issue by setting he origin to pin 1 instead of center for the footprint. you can do this under EDIT/Set reference/Pin 1 with the PcbLib file open.

this has nothing to do with the 3D.

Hello John

Dizar here, stepping in for Carlos. Thank you for your patience while we reviewed your feedback regarding the footprints. :slightly_smiling_face:

We checked the 2D footprint models for both RKE-0505S/H and RYK-053.3S/H, and in both cases the origin is placed at the center of the body outline. At this time, we have not been able to reproduce any difference in the footprint origin on our side.

Could you please share the part page link or confirm the exact part number you downloaded where the footprint origin appears differently? That will help us review the same data, reproduce the issue, and make any necessary updates as quickly as possible.

For reference, the 3D models were originally provided by the manufacturer and used a different origin standard from our internal one, which caused a 2D to 3D alignment issue. We have already updated the 3D models so their origin now aligns with the footprint reference.

We truly appreciate your help and look forward to your reply. Thank you again for bringing this to our attention. Feedback like yours helps us improve the libraries and provide better quality for all users. :blush:

Best Regards
