What it is — the 430451602 in the Micro-Fit 3.0 43045 series
The Molex 430451602 is a 16-circuit, dual-row right-angle male header in the Micro-Fit 3.0 43045 family, operating at 3.00 mm pitch. The dual-plating stack puts gold (0.76 µm) on the mating interface for wear resistance across reconnect cycles, and 2.54 µm tin on the solder tails for reliable through-hole wetting. Rated 8 A per contact and 600 V — the headroom covers both signal and power-duty wire-to-board junctions in a single footprint. The shroud extends four walls around the pin array, and the locking ramp on the housing side of the mate locks the two halves together with positive audible feel — the board-lock feature on the header body anchors it to the PCB during assembly and in service. The LCP insulator carries a UL94 V-0 flammability rating, consistent with its use in automotive and industrial enclosures.
