The Molex 0430451624 is a 16-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects.
The 3.18 mm post length (0.125") fits a standard 1.6 mm PCB — the kinked pin keeps the header square to the board during solder. Against the 10-circuit sibling in the same series (430451210), this 16-position version gives you six more circuits at the same 3.00 mm pitch and 8 A rating — the board footprint just extends by 18 mm along the row. No change in current headroom or mating half; it is a straight position-count decision.
