The 16 A per circuit rating means each blade is sized for bus-level current — this is a power header, not a signal line. The 919991284 shares the same 5.00 mm pitch, 16 A rating, and latch-lock fastening as the 2-position 919990499. The difference is position count — 4 circuits here against 2 on the sibling — and contact finish: this one uses tin (118.1 µin), while the 919990499 carries silver (78.7 µin). For a 4-circuit power BOM line, the 919991284 matches the position count directly; the tin plating is adequate for standard indoor duty, but if the assembly sees higher mating-cycle counts, the silver-plated sibling offers better fretting resistance.","metaTitle":"Molex Appli-Mate 919991284, 4-Pos 5.00mm Header, 16 A, Tin","metaDescription":"Molex Appli-Mate 91999 919991284 header, 4 positions, 5.00mm pitch, 16 A, 250 V, tin contacts, latch lock, active production, RoHS3.
