The Molex 430450212 is a 2-circuit, dual-row vertical header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects. It carries 8 A per circuit at 600 V on a 3.00 mm pitch — the pitch gives enough creepage for the voltage rating without an oversized footprint.
The 2-position count is the defining fit parameter — this header mates one circuit pair in a dual-row body, so the BOM line is a single power pair. The 3.00 mm row spacing matches the Micro-Fit 3.0 receptacle pitch. Tin plating on both the mating surface and the solder post (100.0 µin, 2.54 µm on the mating side) is rated for moderate mating-cycle duty; for higher reconnect life, a gold-plated variant in the same series would be the pick. The kinked pin through-hole termination gives mechanical retention in the board before soldering.
This is the board-mount half of a wire-to-board interconnect. It mates with the matching Micro-Fit 3.0 receptacle housing (sold separately) that accepts 20-24 AWG crimp terminals.
