I am ordering the parts to build the Post War Relay Replacement board, as found in the Hobby section of the ERR web site.
As it turns out, the specified relay is no longer available. It's marked as OBSOLETE. So, I did a bit of scouting and, before I order it, would like somebody with good eyes to make sure my replacement is good fit.
OLD PART: 425-1210-5-ND (Digi-Key part number)
NEW PART: 255-5981-ND (Digi-Key part number)
They are both 4-SIP packages, have very comparable voltage/amperage numbers. The thing that concerns me is that the "Series" is different. I don't know what Series means in this context. And considering that this part is $18 each, I would like to get it right to begin with! :-)
Thanks in Advance!
