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.","metaTitle":"Molex 91999-0478 RAST 5 Header, 2 Pos, 5.00mm, 16 A","metaDescription":"Molex 91999-0478 RAST 5 vertical header, 2 positions, 5.00mm pitch, single row, through-hole, silver-plated contacts, 16 A, 250 V, latch lock.
