20-Circuit Receptacle Housing in the Mini50 Gen II Family
The Molex 2065230203 is a 20-circuit receptacle housing from the Mini50 Gen II series, identified by the description "MINI50 GEN II 20CKT HB RCPT POL". The "POL" suffix confirms the housing is polarized, meaning it has a mechanical keying feature that prevents incorrect mating orientation, a practical safeguard on an assembly line or during field service. The Mini50 Gen II family is Molex's compact 0.50 mm blade-and-receptacle system designed for high-density wire-to-board and wire-to-wire connections in space-constrained automotive and industrial applications. The 20-circuit count here suits harnesses that need a moderate number of signal or low-power circuits in a single connector body, such as an interior control module or a sensor cluster.
For a BOM that requires RoHS compliance, this part checks that box without needing a waiver. The Bulk packaging means the housings ship loose, not on tape and reel, which is standard for hand-loaded harness assembly.
