The Molex 0430451824 is an 18-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire interconnects in automotive, industrial, medical, and telecom equipment. It carries 18 positions loaded across two rows at the series-standard 0.118" (3.00mm) pitch — matching the footprint for the mating receptacle housing. Rated 8A per circuit at 600V, with tin-on-tin contact finish at 60.0µin (1.52µm) on the mating side, suited for moderate-cycle applications where cost per position matters more than high-mating-cycle gold.
Key features and deployment context
The 4-wall shrouding and integrated locking ramp provide positive retention and pin protection in vibration-prone environments — the latch audibly clicks when fully mated, giving the harness builder a tactile confirmation. The glass-filled LCP housing carries a UL94 V-0 flammability rating and operates from -40°C to 105°C, covering under-hood automotive and industrial cabinet temperature profiles without derating the 8A per-circuit current. The 0.125" (3.18mm) post length suits standard 1.6mm PCBs.
