The Molex 430452414 is a 24-position, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects.
The 24 circuits at 3.00 mm pitch give you a compact dual-row footprint that still leaves enough board space for routing between the through-hole vias. The 8 A per-contact rating is the headline current, but the real duty limit comes from the temperature rise across the full 24-circuit load — the -40°C to 105°C operating range and UL94 V-0 LCP housing keep the connector stable inside an enclosure even under sustained current. The locking ramp fastening means the header holds the mating receptacle positively against vibration and cable tug — a detail that matters when this connector lives in an automotive harness or an industrial cabinet where the wire bundle gets moved during service.
