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.","metaTitle":"Molex Sabre 431603103 Header, 3 Pos, 7.50mm, R/A, 18A","metaDescription":"Molex Sabre 43160 431603103 3-position single-row male header, 7.50mm pitch, right-angle through-hole, tin-plated contacts, 18A, 600V.
