14-Position Micro-Fit 3.0 Header for Wire-to-Board Power
The Molex 430451413 is the 14-circuit, dual-row member of the Micro-Fit 3.0 43045 series — a shrouded, through-hole header designed for board-to-cable/wire power interconnects. It carries 14 positions on a 3.00 mm pitch, with a full 4-wall shroud that protects the square male pins during handling and prevents mis-mating with the matching receptacle housing. Rated 8 A per circuit at 600 V, with 15.0 µin gold on the mating interface and tin on the solder tails, this header is built for applications where repeated mating cycles and environmental exposure are routine: automotive harnesses, industrial control cabinets, medical equipment, and telecom infrastructure.
The 8 A per-circuit rating is the series maximum for Micro-Fit 3.0 — each contact is sized to carry power-level current, not just signal. At 600 V, the 3.00 mm pitch provides enough creepage distance for the voltage rating without forcing an oversized board footprint. The locking ramp fastening gives a positive audible latch that holds against vibration — no secondary hardware needed. The -40°C to 105°C operating range and UL94 V-0 LCP housing confirm this header is qualified for equipment inside an enclosure where flame rating is mandatory.
