M80-5T12642B1

Overview

The M80-5T12642B1 is a Datamate J-Tek male header connector featuring 26 positions arranged in a dual in-line (DIL) vertical configuration. It utilizes a 2.7mm pitch and employs PC-tail termination for through-hole mounting. The assembly includes a shrouded design with keying to ensure correct mating orientation. Constructed with brass contacts finished in gold over nickel, the housing is made of black polyphenylene sulfide (PPS). This component is rated for 3A current and 120V, designed for reliable board-to-board or board-to-cable interconnections.

Feature Summary

• Vertical DIL male pin configuration with shrouded housing
• PC-tail termination for secure through-hole board mounting
• Gold-plated brass contacts for corrosion resistance
• Integrated keying mechanism for polarized mating

Applications

• LED or diode testing equipment interfaces
• Industrial control board interconnects
• Embedded system module connections

Procurement Notes

Verify the specific suffix 'B1' against the official Harwin datasheet to confirm contact finish and material specifications. Ensure the required stacking height matches the application's mechanical constraints. Confirm RoHS compliance status if restricted substances are a project requirement. Cross-reference the part number with the latest Harwin product discontinuation notices to avoid sourcing obsolete inventory.

Selection Notes

Select this connector when a vertical, shrouded male header with PC-tail termination is required. The 2.7mm pitch offers higher density than standard 2.0mm connectors while maintaining robust mechanical stability. The gold-over-nickel finish supports environments requiring moderate corrosion protection. Ensure mating receptacles match the DIL vertical form factor and keying position.

Part Context

This component belongs to the Harwin Datamate J-Tek series, known for high-density interconnect solutions. The M80 prefix indicates the specific connector family within the broader Harwin portfolio. As a male header, it pairs with female sockets to create secure electrical pathways in compact electronic assemblies.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Generic replacements may not match the 2.7mm pitch or PC-tail termination style. Verify mechanical compatibility before considering alternative vendors.
