M80-4202042

Headers, Receptacles, Female Sockets Overview

The M80-4202042 is a Datamate J-Tek series receptacle connector manufactured by Harwin Inc. It features 20 positions arranged in a dual in-line configuration with a 2mm pitch. Designed for through-hole mounting, the connector utilizes female socket contacts made of beryllium copper, finished with gold plating on the mating interface and tin on the tail. The housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0 for flammability. It supports board-to-board or cable applications with a rated voltage of 120V and operates within a temperature range of -55°C to +125°C.

Headers, Receptacles, Female Sockets Procurement Notes

Verify component authenticity against official Harwin documentation before integration. Confirm that the specific ordering suffix matches the required jack screw type and contact finish specifications. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit sources. Validate mechanical dimensions against PCB layout requirements prior to procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a robust, high-density interconnect solution is required for harsh environments. The dual-row format maximizes pin count within a limited footprint. The jackscrew feature is critical for applications subject to vibration or mechanical stress. Consider the 2mm pitch constraint relative to adjacent components. Evaluate the thermal performance of the PPS material against the operational temperature profile of the target system.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Datamate J-Tek family, known for its modular connectivity solutions. The M80-420 series specifically denotes receptacles with hex slotted jackscrews. The suffix 42 indicates gold plus tin contact finishes. This series is engineered for demanding applications requiring high reliability and repeated mating cycles compared to standard connectors.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Harwin Datamate J-Tek receptacles with identical 20-position, 2mm pitch, and jackscrew configurations. Verify compatibility of mating plugs regarding keying and polarity. Alternative manufacturers may offer similar form factors but require rigorous validation of electrical and mechanical interfaces.
