B5743-106-M-L-1

Overview

The Harwin B5743-106-M-L-1 is a Datamate L-Tek male header connector featuring a 2.00mm pitch and six positions in a single row configuration. It utilizes vertical through-hole solder termination with pin lock retention mechanisms. The mating contacts are gold-plated, while the tail contacts feature tin/lead plating over a nickel barrier. Constructed from phosphor bronze contacts and black glass-reinforced polyester insulation rated UL94 V-0, it supports a current rating of 2.2A at 120VAC/DC across an operating temperature range of -55°C to +125°C.

Feature Summary

• Datamate L-Tek series design for high-density interconnect applications
• Pin lock retention system ensures secure mating engagement
• Selective contact plating with gold on mating surfaces and tin/lead on tails
• Vertical board-to-board or cable mounting style

Applications

• Industrial control systems requiring robust mechanical retention
• Test and measurement equipment interfaces
• Embedded electronics modules needing reliable signal transmission
• Automotive electronic sub-systems within specified thermal limits

Procurement Notes

Verify the specific suffix 'L' indicates the right-angle orientation variant distinct from standard vertical headers. Confirm RoHS compliance status as some variants may differ. Ensure the tin/lead tail plating meets project material restrictions. Cross-reference the exact pin count and row configuration against schematic requirements before finalizing procurement orders.

Selection Notes

Select this component when a right-angle male header with pin lock retention is required for 2.00mm pitch applications. The 2.2A current rating suits moderate signal and power loads. Consider the UL94 V-0 insulation rating for fire safety compliance. Evaluate the operating temperature range against environmental conditions to ensure reliability throughout the product lifecycle.

Part Context

This part belongs to the Harwin Datamate L-Tek family, known for compact, high-reliability connectors. The B5743 series specifically denotes male headers with pin locks. The '106' identifier specifies the six-position count. This model complements female receptacles and cable assemblies within the same ecosystem for complete interconnect solutions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 2.00mm pitch, 6-position count, right-angle orientation, and pin lock mechanism. Verify compatibility with existing mating female components before substitution.
