If it is the same issue, could you please private message me. I am currently speaking with PCBWay about this and another separate issue.

HighVoltage Posted June 7, 2021 Share Posted June 7, 2021 (edited) Does anyone know a compatible replacement for part D1 in the BOM? It is STM BAT60JFILM. There seems to be a shortage of this part. I found the specs here: ST BAT60J DataSheet And tried to filter for similar part here: Newark part search This is the closest I could find. Would this work? Infineon BAT60AE6327HTSA1 Anyone have a suggestion or better place to search? Edited June 7, 2021 by HighVoltage Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted June 7, 2021 Author Content Provider Share Posted June 7, 2021 DigiKey has them in stock https://www.digikey.de/product-detail/de/stmicroelectronics/BAT60JFILM/497-3707-1-ND/686425 Link to comment Share on other sites More sharing options...
HighVoltage Posted June 7, 2021 Share Posted June 7, 2021 (edited) Probably Chinese contract manufacturers don't order parts from US suppliers though. I've noticed some retail providers do have stock too, but others that don't have 6 months or more order time. I probably need a Chinese-source supply. I thought chances were better to find an alternative part at Chinese source. Or were you suggesting I should order the assembly without them and add them to the delivered boards myself? I didn't think of that, but seems like a relatively simple SMT part. So maybe possible. Edited June 7, 2021 by HighVoltage Link to comment Share on other sites More sharing options...
Chesco Posted June 8, 2021 Share Posted June 8, 2021 (edited) Good morning. I have received confirmation to continue manufacturing. They has installed "Tantalum capacitor, 2u2, 20V, 3528" instead of 35V. Any problem with this change? I can give confirmation ok? Thanks.

This is a known substitution at the moment due to supply issues. Lucky has said before this will be ok. Link to comment Share on other sites More sharing options...

You can order from Digikey and install the part yourself when it arrives, it is fairly simple if you are good at soldering. You can find a Chinese supplier or you can order from Digikey and get it sent direct to PCBway (or from any other suppliers). It may just be shipping costs that are extra.

HighVoltage Posted June 11, 2021 Share Posted June 11, 2021 (edited) Have had multiple contract manufacturers tell me there is no stock. Pointed one to DigiKey, but didn't hear back. They're now out too, anyway. Maybe they grabbed the rest, ha. If anyone doesn't need all the boards in their order, I'd be interested in sharing your order.

Content Provider lucky1 Posted June 11, 2021 Author Content Provider Share Posted June 11, 2021 If it is only the Bat60J you can replace it with a zero Ohms resistor. That powers the CPU with 3.3V instead of 3V which is also within the specs. But I think the CPU availability is also getting worse. Link to comment Share on other sites More sharing options...
HighVoltage Posted June 12, 2021 Share Posted June 12, 2021 (edited) Do you know one that will drop in? I tried to find one, but didn't. Also came across various wattage ones, wasn't sure how high that had to be either. Do you recommend just leaving it out and then just jumper it later: I assume that's effectively the same as a 0-ohm resistor.

Just tell pcbway to do so or change the BOM accordingly. Link to comment Share on other sites More sharing options...
thiagomax Posted June 16, 2021 Share Posted June 16, 2021 Hey Guys, i nee help with a question from pcbway, they send me a picture for the diode SK54BTR, in the picture the diode is too big for the assemble, i need help with a equivalent and the right size diode.

Content Provider lucky1 Posted June 16, 2021 Author Content Provider Share Posted June 16, 2021 The diode on the picture is not a SK54B diode (DO214AA). It is a SK54 (DO214AB) Link to comment Share on other sites More sharing options...

Chesco Posted June 17, 2021 Share Posted June 17, 2021 (edited) Good afternoon. I have just received the Boards with the latest BOM files. In the last boards, this connector was for 12V, however, in these it appears 8-36V ... Can I connect the 12V and will it work perfectly as in the previous boards? Thanks. http://imgfz.com/i/SMgYW8X.jpeg Edited June 17, 2021 by Chesco Link to comment Share on other sites More sharing options...

Audiofreak Posted June 18, 2021 Share Posted June 18, 2021 By my latest orde i have to pay the same amount just for the parts as i paid for the last complete order.. At the moment all is geting worse, the price for LED panels are also rising from day to day... A week ago 13.50$ each, yesturday 15$, today 17.50$. Bad time to produce 🙈 Link to comment Share on other sites More sharing options...
dzorbas Posted June 19, 2021 Share Posted June 19, 2021 Yup, we are all getting hit with increases. The $8 USD processor was $28 USD this time around. LED panels have gone up in price as well. Overall costs have increased $20 to $30 USD with this last order of parts. Then again, ColorDMD has increased their prices by $20 USD as well.
