M80-7402742

Overview

The Harwin M80-7402742 is a Datamate J-Tek series vertical board-to-board header connector. It features a 27-position configuration with a 2 mm pitch across two rows. The contacts are male pins made of phosphor bronze with gold plating, rated for 3 A current and 120 V voltage. Designed for through-hole solder termination, the housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, ensuring UL94 V-0 flammability rating. The unit operates within a temperature range of -55°C to +125°C.

Feature Summary

• Datamate J-Tek interlocking system provides secure mechanical retention during mating
• Gold-plated phosphor bronze contacts ensure reliable electrical conductivity
• High-temperature PPS insulation supports demanding thermal environments
• Vertical orientation facilitates compact PCB layout integration

Applications

• Board-to-board interconnects in industrial control systems
• Signal routing in automotive electronic modules
• Data transmission links in military communication equipment
• Power distribution connections in general-purpose electronics

Procurement Notes

Verify the specific suffix codes against official Harwin documentation to confirm exact pin count, contact material, and termination style. Ensure compatibility with mating receptacles within the same Datamate J-Tek family. Confirm RoHS compliance status via the manufacturer's latest declaration before finalizing procurement orders.

Selection Notes

Select this component when a high-density 27-position vertical interface is required. The 2 mm pitch allows for significant signal density on limited board space. Verify that the 3 A current rating meets the application's power requirements. Ensure the through-hole mounting style aligns with the target PCB manufacturing capabilities.

Part Context

This part belongs to the Datamate J-Tek line, known for robust mechanical locking and high reliability. It complements female receptacles and cable assemblies within the same ecosystem. The design emphasizes durability and consistent performance in vibration-prone environments typical of aerospace and defense sectors.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing with other Harwin Datamate variants requires careful verification of pitch, row count, and locking mechanism compatibility.
