Connector Identity and Series Position
The Molex 430450611 is the 6-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, 3.00 mm pitch header designed for board-to-cable interconnects in automotive, industrial, medical, and telecom applications. All 6 positions are loaded with square-pin male contacts in a shrouded housing that accepts the matching Micro-Fit 3.0 receptacle.
Key Selection Ratings
Current rating is 8 A per circuit, governed by the brass contact material and the dual-plating strategy: 30.0 µin (0.76 µm) gold on the mating face for wear resistance and low contact resistance at first mate, over 100.0 µin (2.54 µm) tin on the solder tail for solderability and long-term oxidation protection. Voltage stands at 600 V, placing this series in mid-voltage wire-to-board duty well beyond signal-level applications. The locking ramp fasteners mechanically secure the mated pair against vibration — a meaningful differentiator versus friction-fit alternatives in transportation and industrial harnesses. The 4-wall shroud adds mechanical keying and prevents accidental pin damage during handling. Operating temperature range spans -40°C to 105°C, with the LCP glass-filled insulator rated UL94 V-0. The 0.290 inch (7.37 mm) insulation height defines the board-side stand-off; the right-angle SMT profile routes the cable exit parallel to the PCB plane.
Sourcing and Compliance
Production status is Active, ROHS3 Compliant per. Packaged in tape and reel (TR) with cut tape (CT) option — the SMT right-angle orientation suits pick-and-place assembly. No official successor or cross-reference is listed for this 6-position member.
