Sabre 43160 Power Header — 6-Circuit, 7.50 mm Pitch
The Molex 431604306 is the 6-circuit member of the Sabre 43160 series, a single-row male blade header built for wire-to-board power distribution. Its 7.50 mm pitch and 18 A per-circuit rating put it in the class of a compact bus interconnect — each blade carries enough current for a moderate DC rail or motor feed, not a signal line.
The 18 A per circuit is the headline number — it tells you this is a power interconnect, not a signal header. Each male blade is sized to carry that current continuously at the rated voltage, so the limiting factor in a harness is the wire gauge and the mating terminal, not the header.
The 431604306 (6 positions) shares the same 7.50 mm pitch, 18 A rating, 600 V, tin plating, and board lock as the 5-position 431600105. The only decision-relevant difference is the position count — 6 circuits vs 5. Both use the same footprint pitch and the same locking ramp, so a panel or PCB designed for the 5-position version can use the 6-position header if the extra circuit is left unpopulated or if the harness adds a conductor. No other spec changes between them.
It is RoHS3 compliant.
