What it is
The Molex 430451413 is the 14-circuit member of the Micro-Fit 3.0 43045 dual-row header series, configured board-to-cable with a through-hole kinked-pin solder tail and a locking ramp that secures the mating half under vibration. All 14 positions are loaded.
Ratings that drive the fit
Current is 8 A per circuit — that headroom covers most in-cabinet power distribution or low-current motor drive taps without derating. The voltage ceiling of 600V handles the common 24V and 48V industrial rails comfortably. Contact plating is split: 15.0 µin (0.38 µm) gold on the mating face, 100.0 µin (2.54 µm) tin on the solder tail. The gold mating finish gives reconnection cycle life — the tin post resists solder-side oxidation in production storage. The 100 µin post thickness is substantial; verify your reflow profile does not reflow the kinked pin geometry. Operating range is -40°C to 105°C, housing material is glass-filled liquid crystal polymer rated UL94 V-0 — that ceiling and V-0 rating together make this viable for under-hood or enclosed-panel environments where thermal cycling and flame retardancy both show up in the spec check.
What the shrouding and board guide mean for the build
Four-wall shrouding surrounds the pin field — it prevents the header from cocking in the PCB hole during wave solder and gives the receptacle housing a positive alignment shoulder on all four sides. The board guide feature on the housing side (post-placement before solder) further reduces misalignment on production runs with long reflow conveyors.
Sourcing
Listed Active with ROHS3 Compliant status — no official successor or cross-reference for this 14-position member. Quoted to order against the BOM quantity; confirm circuit count and mating half before committing the line.
