NEC / Renesas UPC1237 are dead as a Dodo. Maybe Renesas parts are still circling around mostly on ebay, Ali and in some God forsaken shops around the globe.
Look for example this ebay seller. He sold 115 pieces. I don't see anyone complaining. UPC1237 on eBay

I have some NOS. How many do you need?I have some builds in progress that require UPC1237 speaker protection ICs, but how do I find genuine ones (ideally in EU)?
I have a couple of older amplifier boards that don't work and I am pretty sure the ICs I put in (from ebay/aliexpress) are the culprit. Since they are also a PITA to remove once soldered in place I would like to ensure I get genuine ICs, but I am not sure where to go as the "usual suspects" don't seem to carry these?
PM me.
