What This 20-Circuit CPA Assembly Is
The Molex 2058264202 is a 20-circuit CONNTAK50 large Connector Position Assurance (CPA) assembly. It's the full housing with the CPA feature integrated — the secondary lock that slides over the terminal position assurance (TPA) to keep the terminals seated under vibration. This is the receptacle side of the CONNTAK50 system, designed for wire-to-wire interconnects in harnesses that see engine-bay or chassis-level shake.
This CPA assembly mates with the corresponding CONNTAK50 male header or plug housing — the exact mating part number depends on whether the harness side uses a straight or right-angle header. The 20-circuit count matches a 20-position wire bundle; the CPA latch audibly clicks when fully seated, giving the harness builder a positive lock confirmation before the assembly leaves the bench. The CONNTAK50 series is common in underhood and body-electronics harnesses where a secondary lock is specified for terminal retention.
RoHS and Compliance
The 2058264202 is RoHS compliant, meeting the directive for restricted hazardous substances in electronic equipment. No additional compliance documentation is required for standard EU-market builds.
