The Molex 1054311105 is a 5-position, single-row male pin header from the Nano-Fit 105431 series, pitched at 0.098" (2.50mm). It is a board-to-wire interconnect — a surface-mount header that mates with the matching Nano-Fit receptacle housing and crimp terminals. The latch holder locks the pair together, which matters in automotive, industrial, and telecom harnesses where vibration can walk an unlatched connector apart.
For a harness that gets mated once and stays, tin is fine.
Board layout and assembly
SMT termination with solder retention features and a pick-and-place surface — this header is designed for reflow assembly on a standard SMT line. The 0.382" (9.70 mm) insulation height means the header stands tall enough to clear components on the board under the mated receptacle.
