RAST 5 Power Header for Appliance Harnesses
The Molex 91999-0478 is a 2-position, single-row vertical header from the RAST 5 family, built on a 5.00 mm pitch. It carries silver-plated brass contacts rated 16 A per circuit at 250 V — that current density at this pitch tells you it's a power interconnect, not a signal line.
The 919990499 is electrically identical — same 2 positions, 5.00 mm pitch, 16 A, 250 V, silver plating, latch lock. The only difference is packaging: the 91999-0478 ships in a Bag, while the 919990499 comes in Bulk. If your pick-and-place or kitting line prefers tubes or trays, the packaging change is the only thing to adjust.
