Sabre 43160 series — mid-power header position
The Molex 431602105 is the 5-circuit member of the Sabre 43160 series, a single-row header line built around a 0.295 in (7.50 mm) pitch optimised for wire-to-board harness in mid-power applications. Male-blade contacts terminate via through-hole solder; the header carries a board-lock feature and a locking ramp for positive retention in the receptacle.
What 18 A per circuit means for the harness
Board lock and locking ramp — what they actually do
The board-lock feature stakes into the PCB during wave or hand-solder assembly, adding lateral retention that a friction-fit header alone cannot provide. The locking ramp on the header body engages a latch feature on the mating receptacle housing — this is not a screw-lock; it relies on the housing plastic to hold under vibration or thermal cycling. For applications with high mechanical demand, verify the receptacle housing's latch material and retention force match the ramp geometry.
Sourcing and compliance
The 431602105 is listed as Active and ROHS3 Compliant under and — confirm quantity and lead time against your BOM schedule via RFQ. The pitch, 5-position count, and tin plating tie this part to the Sabre 43160 series; verify the mating half in your harness drawing carries the matching position count and receptacle latch geometry before ordering.
