What This Connector Is and Where It Fits
The Molex 430450602 is a 6-circuit, dual-row, right-angle through-hole header from the Micro-Fit 3.0 43045 series. It's a board-to-cable/wire interconnect — the shrouded four-wall housing with a locking ramp mates with the matching Micro-Fit 3.0 receptacle to form a positive-latching harness connection. Typical applications span automotive, general-purpose industrial, medical, and telecom gear, where the 3.00mm pitch and 8A per circuit rating suit moderate power distribution inside an enclosure.
Key Specs That Drive the Fit
6 positions, all loaded, across two rows at 3.00mm pitch — the same footprint as every other dual-row Micro-Fit 3.0 header, so the board layout stays consistent if you swap position counts within the series. The 8A per-circuit rating at 600V is the headline number, but what really governs the duty here is the contact finish: 30.0µin gold on the mating surface, 100.0µin tin on the solder posts. That gold layer buys you repeated mating cycles in a field-service environment — the tin tail is standard for wave-solder wetting.
Mounting and Retention Details
Right-angle through-hole mounting with a board lock — the lock holds the header in place during wave solder and resists shear from cable strain after mating. The four-wall shroud protects the male pins from damage during handling and guides the receptacle home. A locking ramp on the shroud gives an audible click when fully mated, which is the kind of positive feedback a field tech wants when reconnecting a harness in a tight cabinet.
Materials and Environmental Range
Housing is liquid crystal polymer (LCP) glass-filled, rated UL94 V-0 — standard for equipment inside an enclosure that needs a flame rating. Operating range is -40°C to 105°C, which covers automotive cabin and industrial cabinet duty without derating. ROHS3 compliant, so no exemption paperwork needed for EU-market builds.
