The Molex 431607302 is the 2-position member of the Sabre 43160 series — a right-angle through-hole header with male blades on a 7.50 mm pitch. It carries 18 A per circuit at 600 V, making it a compact power interconnect for board-to-wire applications in industrial control cabinets, power distribution units, and similar equipment where the board edge needs a locked, high-current connection.
If your application calls for frequent reconnection, a gold-plated sibling in the series would hold up better. Operating range of -40°C to 75°C — the upper limit is fine for indoor enclosures and most industrial cabinets, but it's a bit low for under-hood automotive or high-temp process zones. The PA46 insulation handles the 75°C ceiling without creep.
Against the 431603106 (6-position, same 7.50 mm pitch, same 18 A and 600 V ratings), the 431607302 is simply a 2-position cut of the same blade design. The position count is the only decision-relevant difference — the pitch, current, voltage, plating, locking ramp, and board lock are identical. If your BOM calls for 2 positions, this is the exact fit; the 6-position version shares the same footprint per circuit but occupies more board edge.
