What this connector is
The Molex 430450214 is the 2-position member of the Micro-Fit 3.0 43045 series — a dual-row board-to-cable header with a 3.00mm row pitch and square male pins designed to mate with the matching Micro-Fit 3.0 receptacle housing. The 4-wall shroud and locking ramp keep the pair engaged under vibration, which is why this series is specified across automotive, industrial, and medical harness applications where mechanical retention matters as much as the electrical rating.
Ratings that drive the selection
8 A per circuit at 600V puts this firmly in power-duty territory — the headline current is governed by the brass contact and the 30µin gold plating on the mating face, not by the tin post finish which handles solder-side integrity. The tin post plating runs thicker at 100µin specifically to survive the reflow thermal cycle without degrading. At 3.00mm pitch the footprint is compact but not dense enough to push the current-per-circuit down to signal levels — an 8A rating on a 2-position dual-row header is usable for low-to-medium power distribution within the harness assembly.
What it mates with
This is a male pin header that mates with the matching Micro-Fit 3.0 receptacle housing. The locking ramp on the header engages the primary latch on the housing; the board guide feature keys the header to the PCB layout before the housing seats.
