Sabre 43160 Power Header — 3 Position, 7.50 mm Pitch
The Molex 431603103 is the 3-circuit member of the Sabre 43160 series, a single-row male header designed for wire-to-board power distribution. It carries 18 A per circuit at a 7.50 mm pitch, giving each blade enough cross-section for a main DC rail or motor feed rather than a signal line. Housing is black glass-filled nylon (PA46).
Position Count Comparison — 3 vs 6 Circuits
The 431603103 (3 positions) shares the same 7.50 mm pitch, 18 A current, 600 V rating, tin plating, and right-angle orientation as the 6-position sibling 431603106. The decision between them is strictly the circuit count matching the BOM line — no change in footprint class, current headroom, or mating half. A board laid out for the 6-position version will accept the 3-position header only if the unused pads are left open; the locking ramp and board lock positions are identical per position.
