Pitch, Pinout, and Footprint Fit
The 77317-803-38LF: All 38 positions are loaded — no skipped or dummy pins — so the pinout is a straight 2×19 grid on 0.100" centers. The solder tails are 0.100" (2.54mm) long with tin finish (78.7 µinch / 2.00 µm thickness), matching the plated-through hole depth on typical 1.6mm PCBs.
