The Molex 430451614 is the 16-circuit member of the Micro-Fit 3.0 43045 series — a dual-row shrouded header rated 8 A per circuit at 600 V, with 0.118" (3.00 mm) pitch and through-hole kinked-pin termination. The contact finish splits across the connector: gold plating (30.0 µin / 0.76 µm) on the mating face drives reconnection durability, while the solder tails carry tin at 100.0 µin (2.54 µm) for wave or hand-solder wettability and long-term oxidation resistance on the board side. The 4-wall shroud, locking ramp, and board-guide feature together prevent mis-mating and hold the header seated under vibration — relevant for any harness assembly that ships or operates mated in automotive or industrial environments.
Mates with the matching Micro-Fit 3.0 plug housing and crimp terminal for the 43045 series — the shroud and locking ramp engage the housing latch to confirm full insertion before the assembly ships as a mated pair.
