The Molex 430451415 is the 14-position, dual-row member of the Micro-Fit 3.0 43045 series, a shrouded male header designed for board-to-wire power interconnect. It carries 14 male square pins on a 3.00 mm pitch in two rows, rated 8 A per circuit at 600 V, with tin-plated brass contacts. Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, mid-current power connection is needed.
The 8 A per circuit rating is the headline spec, but the 3.00 mm pitch is what sets the board footprint — it gives enough creepage for the 600 V rating without forcing an oversized layout, and the dual-row arrangement means the 14 positions fit in a compact 7 x 2 pattern. The locking ramp and board lock together mean this header stays mated and stays soldered through the vibration profile of an automotive or industrial enclosure.
This is a surface-mount header, so it reflows onto the board with no through-hole solder tails. It mates with the matching Micro-Fit 3.0 receptacle housing (the 14-position dual-row version) which accepts the crimp terminals and wires.
