The Molex 430450629 is a 6-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed as a board-to-wire interconnect. Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, field-mateable connector is required.
The 8 A per circuit rating at 600 V is the headline power spec, but the contact finish is what governs the real duty cycle here.
The 430450629 is an active, standard-series part from Molex. There is no official second-source cross-reference on record, but the Micro-Fit 3.0 family is widely inventoried across the channel.
