The Molex 430450228 is a 2-circuit, dual-row vertical through-hole header from the Micro-Fit 3.0 43045 series. It's a board-to-wire interconnect — the male pins mate with a corresponding receptacle housing and crimp terminals, locking in place with a ramp-style latch. The 3.00 mm row spacing and 8 A per circuit rating put it in the mid-power range: enough for a DC power feed or a pair of sensor lines, not just signal-level duty. Applications span automotive, general-purpose industrial, medical equipment, and telecom — the UL94 V-0 LCP housing and 600 V rating clear the regulatory bar for equipment inside an enclosure.
The gold mating finish (15.0 µinch) over brass contacts suits repeated mating cycles. The through-hole mounting with 0.125" post length and tin finish on the solder tail suits standard wave-solder processes. The dual-row layout means the 2 positions occupy a single row of the footprint — one pin in each row, spaced 3.00 mm apart.
