Modern Equivalent for UPD858 Relay?

loosecannon · Jan 3, 2026

So what are people using these days when needing a replacement?

yes, 12v 3PDT relays can be had for 5 bucks on amazon but i think the pin spacing footprint is different.

I don't have one in front of me right now to measure and confirm so i thought i'd ask the group.

thanks in advance!

OMRON 3PDT, MX3P-US-DC14 - there are electrically equivalent replacements, although physical dimensions do not match. Therefore, there are no new drop-in replacements, only vintage. I went down this rabbit hole recently to confirm.
