Product Overview
The Molex 0009623043 is a 4-position single-row receptacle from the KK396 2145 series, designed for board-to-board or cable interconnect applications. It uses a 3.96mm pitch, which provides enough creepage for the 600V rating without forcing an oversized board footprint. Rated at 4.5A per circuit with gold-plated mating contacts (15.0µin), this connector is suited for signal and moderate power duty in automotive, general purpose, medical, and telecommunications equipment. The operating temperature range of -40°C to 80°C covers most indoor and automotive cabin environments, though the 80°C ceiling means it should not be placed near heat sources like power resistors or transformers without thermal analysis.
Given the obsolete status, any remaining stock is finite — the buyer should secure inventory for remaining production runs or identify a board-level replacement.
This receptacle accepts square female sockets with gold-plated mating surfaces. It mates with the matching KK396 male header (same 3.96mm pitch, single-row). Termination is through-hole solder — the 0.120" post length suits standard 1.6mm PCBs.
