What this header is
The Molex 431602102 is the 2-circuit member of the Sabre 43160 series — a single-row male-blade header with 0.295-inch (7.50 mm) pitch built for power-distribution applications in industrial automation and equipment wiring. At 18 A per circuit and 600 V, it sits below the series' higher-current variants but carries the same footprint pitch, which means a BOM position count of 2 is the primary fit check before anything else.
Key ratings and what they mean for the fit
18 A per circuit at 600 V gives meaningful headroom for a 2-position power node — the circuit count, not the current ceiling, is the constraining selection factor here. The contacts are tin-plated at 60.0 µin (1.52 µm) over brass — a standard solder-grade finish with adequate wipe for a through-hole solder joint, but one that limits re-mating cycle life compared to gold. If the application calls for repeated field reconnects, the plating grade is the rating to revisit. The through-hole body includes a board lock feature — those，侧翼塑膠肋在焊接時提供側向保持力，減少墊翹的風險. The locking ramp on the housing mates with the receptacle's cam action to resist vibration pull-out, which matters more in equipment-side connections than in harness jumper positions.
