Sabre 43160: 3-position right-angle, power-class at 7.50 mm pitch
The Molex 431605303 is the 3-circuit member of the Sabre 43160 series — a single-row right-angle through-hole header with 0.295" (7.50 mm) pitch. Tin-plated brass contacts carry 18 A per circuit at up to 600 V, which puts this squarely in power-interconnect territory: the PA46 glass-filled insulator is rated -40°C to 75°C, and the contact finish is 60 µin (1.52 µm) of tin — not a flash, which matters for current-carrying permanence in a harness or panel feed. Board-lock feature on the header body holds the unit in the PWB during wave solder; the locking ramp on the housing side provides the positive latching detent when the mating receptacle seats. Both are mechanical — they do not affect the 18 A / 600 V electrical rating but they do govern assembly retention and vibration performance in the field.
Peer comparison: same series, different circuit count
The 431600105 (5 positions) and 431600106 (6 positions) are straight-through-hole orientation — they require a different board layout than the right-angle 431605303 and are not direct panel-drop alternatives.
Sourcing and compliance
Listed as Active with ROHS3 Compliant status — no NRND, obsolescence, or end-of-life notice filed. No official successor order code is listed in the lifecycle data for this part. For a 3-position right-angle header at 18 A / 600 V, RFQ against this exact code is the procurement path; confirm position count against the BOM before committing, since no drop-in alternative with a different circuit count is a direct substitute.
