Im looking to order the SMD components. I looked at the BOM generated from the KiCad files, as well as the Google Drive sheet linked here. After searching for some of these parts, Ive found out that quite a few have been marked as obsolete by Digikey and are no longer being offered. Is there an updated BOM somewhere? Or a list of suitable substitutes? I am not super great at circuit design, but I do know enough to generate the gerber files, order the stencil and solder the components. So I apologize if this is a stupid question.
It’s not a stupid question, and finding replacement parts is a large and difficult part of making electronics.
There is not an updated BOM, but I can maybe help with finding replacement parts. There was also a thread on TRA recently that had some suggestions in it.
Ok, I am in no rush. I appreciate your offer to help!
Here is a list of the ones I’ve found that appear to be discontinued:
(Sorry the forum wont let me post more than two links, so I put down the manufacturer part number)
Most of the other parts are simply out of stock. I may just end up putting this project off until the chip shortage works itself out. I’m gonna have to find a substitute for probably 70% of the items on this list lol.
Anyways, appreciate the help.
This thread has some suggestions for the crystal:
For the motion chip, LSM6DSM or LSM6DS3TR-C would be viable replacements.
The 2x22 ohm resistor needs a little bit more research. Anything from 18 ohm to 33ohm should work fine though.
Thank you! Digikey made some suggestions at the bottom of the page for the crystal. The specs were the same, but I was worried about the footprint. So this helps a lot! Thanks!
In case anyone else cares, this appears to be nearly identical to the 2x22 ohm resistor that is obsolete: https://www.digikey.com/en/products/detail/panasonic-electronic-components/EXB-24V220JX/256198
