I’ve been looking through the BOM for the BeagleBone Black to sort out alternatives for an industrial variant (lead times through my normal supplier keep going up). I noticed some parts were not stocked by any major distributors with long factory lead times. I suspect these components may be to blame for my supply chain troubles. Can anyone validate the alternative parts below?
U12: Alliance Memory AS4C256M16D3LB-12BIN
U13: ISSI IS21ES04G-JCLI
Y2: Abracon ABM3C-24.000MHZ-D4Y-T
Y3: ABRACON ABM3C-25.000MHZ-D4Y-T
I’m having a hard time finding alternates for the following components:
U11, D8 (limited availability)
For D8 in particular, can anyone point out the critical parameters to match?
