What it is
The Molex 430450615 is a 6-position dual-row shrouded header in the Micro-Fit 3.0 43045 series — board-to-cable orientation, surface-mount terminated, with male pin contacts housed in a glass-filled LCP body rated UL94 V-0. All six positions are loaded; the housing stands 0.390" (9.91 mm) above the board surface when seated.
Ratings that drive the selection
Pitch is 0.118" (3.00 mm) with dual-row spacing of 0.118" — standard Micro-Fit 3.0 geometry, so the footprint matches any other 3.00 mm pitch member in this series. Current is 8 A per circuit; the contact material is brass and both the mating face and solder-tail finish are tin at 60.0 µin (1.52 µm) thickness — a finish grade suited to higher-cycle industrial mating without the cost溢价 of gold. Voltage rating is 600V, well above the typical 250V bus this series normally targets, giving real headroom in industrial power distribution. Operating temperature runs from -40°C to 105°C, which brackets most harness and under-hood environments.
Retention and polarisation
The 430450615 carries a four-wall shroud and a locking ramp — the shroud gives full polarisation coverage against mis-mating, and the ramp locks the receptacle positively once seated. A board-lock feature on the housing body provides lateral retention on the PCB during SMT reflow, addressing the coplanarity risk that unguessed SMT headers face on extended wave or hand-assembly runs. Contact shape is square, which is standard for this series and accepts the matching Micro-Fit 3.0 crimp receptacle without modification.
Lifecycle and sourcing posture
Production status is Active and the part carries ROHS3 compliance. No official successor or cross-reference is listed.
