10 of 12 Positions — Breakaway Footprint
The 77314-163LF: This is a 12-position header with 10 positions loaded — the two empty pin sites are part of the breakaway design. The PCB footprint should match the full 12-position pattern; the unloaded positions can be left as bare pads or used for routing clearance.
Gold GXT Mating Surface — 30 µinch
The mismatch between gold mating face and tin tails is deliberate: gold on the wear interface, tin on the solder joint.
Through-Hole Assembly — No SMT Reflow
This part goes through wave solder or selective solder — not reflow.
