I spent way too much time going through datasheets and manufacturers website and I think that a Triad FS12-200
(mouser part # 553-FS12-200) is an equivalent to the Tamura 3FD-312. Unfortunately at $9.00 each instead of $4.30 each
At least this was at work and not taking up any of my 'spare' time.
Boy I wish I hadn't been broke during the coop
I will order 3 of these to try and will let you know....please don't anyone else try this on my not-real-sure say so.
I am hoping that when I try it my board doesn't go
