I'm in the position of having to order batches of ~50 boards at a time, and since the beginning of this year more and more electronic parts have been out of stock, even though we designed everything for normally in-stock parts.Crystals, real-time clocks, solid-state sensors, MCUs, amplifiers, a lot of what's in IoT devices, are now up in 30-52 week lead time range. Often there aren't even alternatives that could be used on a redesigned board. STM, NXP, TI, Bosch, almost any brand seems to be affected.Does anyone have any insight into where everything went? Are the parts being hoarded, or has there been a genuine large slump in part production or assembly going through the roof?Are there platforms outside of the regular big distributors (eg. digikey/mouser/etc) where the elusive parts are potentially being traded in low volumes?
