The Molex 430451624 is a 16-position member of the Micro-Fit 3.0 43045 series — a dual-row, shrouded header for board-to-wire power interconnects.
8 A per circuit on 3.00 mm pitch is a solid power rating for a wire-to-board interconnect — the 3.00 mm spacing gives enough creepage for the 600 V rating without forcing an oversized board footprint. The 0.125-inch post length and kinked solder tail lock the header in the board during wave solder — no secondary hold-down needed.
Mates with the matching Micro-Fit 3.0 receptacle housing (dual-row, 16-circuit) and the 43030-series crimp terminals. The locking ramp clicks into the receptacle latch — you hear the engagement. The board guide aligns the header during assembly and takes the shear off the pins.
