The 76314-203LF: Confirm the mating header part number and position count before committing the BOM line.
Brass contacts with gold-over-nickel on the mating surface (39.4 µinch) and tin on the solder tail (78.7 µinch). The dual plating strategy gives corrosion resistance at the interface and solderability at the board joint. The thermoplastic polyester glass-filled housing resists reflow temperatures and provides dimensional stability through wave solder. Through-hole termination — the 0.135" post length fits standard 0.062" to 0.093" PCBs with enough protrusion for a reliable solder fillet. The square contact shape mates with square or round header pins of the same pitch.
