I didn't think this measurements on the relay pins sounded right so I measured some with a caliper, those are the 2 width numbers.. The Finder measurements are pretty close at 1mm x .5mm but the thin dimension on the Schrack relays are as thin as .225 mm, less than half the Finder's.
Then the length is a problem too as the Schrack pins at 3.175mm barely reach into the blue Finder relay sockets as those pins range from 5mm to 5.8mm.
