The Molex 430451607 is the 16-circuit member of the Micro-Fit 3.0 43045 dual-row header series, configured for board-to-cable interconnects in sealed and high-vibration environments. It mates with the matching Micro-Fit 3.0 receptacle housing and terminates via standard surface-mount solder to the PCB. The 3.00 mm pitch, four-wall shroud, and locking ramp deliver a vibration-resistant latch — the board-lock legs on the header body anchor it during SMT reflow so no secondary fixturing is needed. Rated voltage is 600 V, giving substantial headroom for most board-level power and signal runs. Operating range is -40 °C to 105 °C with UL94 V-0 flammability rating on the liquid crystal polymer housing — qualification-ready for automotive and industrial equipment boards that need thermal cycling clearance. The insulation height of 0.290" (7.37 mm) sets the board-stack clearance for any right-angle daughter-card or cable-intercept layout. Applications span automotive harness intercept, industrial automation I/O, medical device board-level interconnects, and general-purpose power distribution. The shrouding and locking ramp together resist vibration loosening — a common failure mode in unshrouded headers used in motor-drive and conveyor-control equipment.
Sourcing posture
The 430451607 is listed Active with ROHS3 Compliant status — no NRND flag, no EOL notice, and no official successor on record. Quoted to order against the BOM quantity. Before committing, confirm the position count matches the harness BOM line and verify the mating half (matching Micro-Fit 3.0 receptacle housing) is specified at the same 3.00 mm pitch and circuit count.
