What this header is
The Molex 919990499 is a 2-circuit, single-row male blade header in the Appli-Mate 91999 series, terminated and mounted through-hole at 5.00 mm pitch. Silver-plated brass contacts carry 16 A per circuit at up to 250 V, and the latch-lock fastening keeps the mating half seated under panel vibration. A board guide feature on the housing aligns the receptacle before the contacts engage, reducing mating misalignment in DIN-rail or panel-mount setups.
Sourcing and lifecycle posture
Listed Active with ROHS3 compliance — no LTB or EOL flag in the current record. Quoted to order against BOM quantity. No official successor code is mapped to this position count and pitch combination, so the Appli-Mate 91999 series itself is the primary sourcing family to search if you need a higher circuit-count member with the same pitch and locking style.
