The Molex 430451625 is the 16-circuit dual-row member of the Micro-Fit 3.0 43045 header series, delivering 8 A per contact at 600 V through a through-hole kinked-pin solder tail. The 3.00 mm pitch and 0.118-inch row spacing keep the footprint compact for board-to-cable power interconnects in automotive, industrial, medical, and telecom harness assemblies.
Plating and mechanical retention
Mating-side contacts carry 15.0 µin (0.38 µm) gold over nickel — the grade that gives the connector its cycle life. The post side is hot-dipped tin at 100.0 µin (2.54 µm), which handles solder-side reflow without gold embrittlement concerns. Four-wall shrouding and the locking ramp prevent mis-mate in panel or harness environments where vibration is a factor.
Board assembly fit
Board guide ribs and the board-lock feature locate the header during wave or manual solder assembly and hold it against mechanical stress after the joint cools. The 0.125-inch (3.18 mm) post length is standard for through-hole assembly; the 0.390-inch (9.91 mm) insulation height clears typical component keep-out zones around the header. Contact shape is square, which seats in standard Molex Micro-Fit 3.0 receptacle housings without adjustment.
Material and flammability
The housing is glass-filled liquid crystal polymer (LCP) rated UL94 V-0 — the standard flame-class requirement for in-cabin automotive and industrial panel zones. Contact material is brass; insulation colour is black.
