B5743-208-M-T-2

Overview

The B5743-208-M-T-2 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features an 8-position, dual-row configuration with a 2 mm (0.079 in) pitch. Designed for through-hole mounting, the male pin contacts are constructed from phosphor bronze and finished with gold plating to ensure reliable signal transmission. The unit supports a current rating of 3 A and operates within a temperature range of -55°C to +125°C.

Feature Summary

Dual-row shrouded design provides secure alignment and prevents misinsertion during mating.
Gold-plated male pins offer corrosion resistance and stable electrical performance over repeated cycles.
Through-hole solder termination ensures robust mechanical attachment to printed circuit boards.

Applications

Industrial control system interconnections
Medical device internal wiring
Automotive electronics modules

Procurement Notes

Verify the specific suffix 'T-2' against official Harwin documentation to confirm exact contact length and insulation height specifications. Ensure compatibility with corresponding female sockets within the same Datamate series. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when a low-profile, high-density connection is required for board-to-wire applications. The 2 mm pitch allows for compact circuit layouts while maintaining adequate spacing. Consider the 3 A current rating for power distribution needs and verify that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the Datamate L-Tek family, known for its small bore design and versatile connectivity options. The B5743 series specifically addresses applications requiring reliable through-hole headers with durable metal contacts. It complements the broader Datamate ecosystem of plugs, sockets, and accessories.

Replacement Considerations

M80-8670822 is a documented equivalent part number for this component. Verify mechanical dimensions and contact plating thickness before substitution to ensure functional interchangeability.
