content: I ordered some SST serial EPROMS from Digi-Key today, they expect delivery from the factory March 12, 2022.I found stock at Mouser, when it comes in, I'll cancel the backorder.Jon

content: Got bit by that digikey "inventory discrepancy" thing last week.Annoying to spend all that time to find and order a part that's showing in stock, just get that email a week later saying they'll ship it in a couple of months (hopefully).Then start the scrambling all over again.

content: I had a board with Altera Cyclone 4 assembled by JLC last month. I thought about running a small batch of the same board but there’s no Cyclone 4 in stock at JLC or LCSC in any package or size. None!It’s really depressing.

content: Seems to be a worldwide shortage in silicon these days. They shut down too many plants when there is a glut then need to rebuild when there is a shortage.

content: I have two boards with nuked STM32s that I thought I just might try repairing until I saw the 44-week lead time.https://www.mouser.com/ProductDetail/STMicroelectronics/STM32F103CBT6TR?qs=SU4Xa%252BYHGQr0GBvhN6Y2ig%3D%3DI don't have the firmware I need anyhow, but I'm not going to be looking for it now either.

content: Not a part but a battery charger and it was cancelled.QuoteThis last week, May 8th. I was rather surprised too, as you don't think of battery chargers as being advanced tech from bleeding edge fabs.

content: And that's why I now see even more in the Electronics Supermarkets parts of PCBs being cut for the main chips like STM32, Altera, etc. They simply pick up old boards, cut a square or a circle around the IC (literally cut) and put in a bag, selling them at 50 each bag. It was prevalent before but now even more.Remember when you started electronics and you used donor boards to de-solder resistors, caps and other parts for further reuse? Well that times are returning...

content: Bonjour:My OEM colleagues (audio, broadcast equipment) mention NO ICs in many categories till end 2021, 2022 or even 2023.What little new prod or inventory is avail for any part is sold by priority to largest OEM orders first and Disty last.Disty inventory and sales EMS systems are JIT based for normal lead times and inventories. They have not been able to adjust to the new and unprecedented logistics and chip shortages worldwide.Small qty purchases from Disty will be automatically accepted and then later voided.Blame the ChiCom virus, Global off shoring of IC fab, suspicious fires in three areas destroying IC fab plants, or (fill in favorite conspiracy) ....Suggest that we EEVers try to adjust as best we can, to a world of poor availablilty and seek workarounds, rather than complains.Bon Chance,Jon

content: Quote from: jonpaul on May 15, 2021, 05:23:34 amNo conspiracy needed. This is a perfectly natural phenomenon that occurs in basically any system with sufficient latency between inputs and outputs, and feedback loops. It's basically just the famousbeer distribution gameat a much larger scale. And of course this is all exacerbated by the increased emphasis on zero-inventory (or near zero), JIT stock delivery, JIT manufacturing, etc over the last few decades, as well as the complex graph of interdependencies in the supply chain. If anything, we should probably all shake our heads in amazement when therearen'trampant shortages, or some other werid sh%@ going on.

content: I had some atmega328's, that were in stock, in my shopping cart at mouser but next day they would be out of stock, so i would switch them out for a different variant of the atmega328, but then that would go out of stock soon after.And so continued this whack-a-mole of out of stock parts for about a week, but fortunately i managed to get some shipped out
