Hello Thank you for writing to us. Please check [the parts library](https://jlcpcb.com/parts), if the connector you that you are looking for doesn't appear in there then it is not supported for assembly. <br> Feel free to let us know if you need any furtehr details

@jlcpcbsupport, @DYEvans, Please note the references to being able to source parts - that are listed but may be out of stock in the JLCPCB library - from DigiKey and Mouser in this topic: [https://easyeda.com/forum/topic/JLC-SMT-RoadMap-in-2021-69a2c931b42244deb9939eac4cafe06d](https://easyeda.com/forum/topic/JLC-SMT-RoadMap-in-2021-69a2c931b42244deb9939eac4cafe06d)<br> <br> There is also this on the JLCPCB pages: [https://jlcpcb.com/help/article/53-What-is-JLCPCB-Parts-Pre-order-Service](https://jlcpcb.com/help/article/53-What-is-JLCPCB-Parts-Pre-order-Service)<br> <br> and in particular Step 8: "Making new parts request".

@andyfierman Thank you, as mentioned in my previous comment if the part doesn't appear in JLCPCB parts library then it is not possible to assemble it (especially if it has specific part footprint) so if it appears in the parts library "even with 0 stock" it means it could be assembled then the customer could source it from external supplier, the "new parts request" is also an option.

Thanks for the information
