Pitch, Positions, and Plating for the Fit Check
The 0.100" row spacing matches the pitch, so the 4 pins occupy a compact 0.200" x 0.100" footprint on the board. Gold on the mating face (30 µinch) versus tin-lead on the solder tail (100 µinch) — the gold side handles the wear of insertion cycles; the tin-lead side wets reliably during wave solder.
