I need a "Silicon Power Cube" which I believe is just a couple of SCR's, potted, on a heat sink. Looks like this:
One side says 8506. The other has a sticker that says M4042. No manufacturer name but searching around I see similar items made by Reliance but I can't cross reference from the numbers I have. It's out of a light dimmer that is rated to handle up to 35A @ 120V. My application is only pulling about 10A so any similar device 15A and up would be fine. I know I can subsitute other SCR's but that means reworking the heat sink etc. and I'd rather replace it in kind.
BTW, I came across a RELIANCE 701819-9X which looks the same except for markings and has two extra spade connectors where my device has spaces for them. I don't know if that would work as I'm trying to find a spec sheet to find out what that actually is. I think some Reliance "Power Cubes" may be rectifiers.
