B5743-106-M-T-R

Overview

The B5743-106-M-T-R is a male header connector from the Harwin Datamate L-Tek series, designed for board-to-board or cable applications. It features a 2-row configuration with 12 positions and a 2.00mm pitch. The connector utilizes vertical through-hole termination with solder pins. Contact surfaces are gold-plated on the mating interface and tin-lead plated on the column. Constructed with phosphor bronze contacts and black glass-reinforced polyester insulation rated UL94 V-0, it supports a maximum current of 2.2A and voltage of 800VAC/DC within an operating temperature range of -55°C to +125°C.

Feature Summary

• Datamate L-Tek series provides secure pin-locking retention for reliable connections in high-vibration environments.
• Four-wall shrouded design ensures proper alignment and prevents misinsertion during mating.
• Gold-plated contact interfaces offer corrosion resistance and stable signal transmission.
• Vertical through-hole mounting facilitates direct PCB integration with standard soldering processes.

Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing reliable signal pathways
• Automotive electronics subject to vibration
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging specifications and orientation. Ensure compatibility with corresponding female receptacles from the same Datamate L-Tek family. Confirm RoHS compliance status and material declarations match project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 12-position, 2-row male header is required for vertical mounting. The 2.00mm pitch suits dense circuit layouts. Consider the 2.2A current rating and 800V voltage limit for electrical safety. The pin-lock feature is essential for applications demanding mechanical stability under shock or vibration conditions.

Part Context

This part belongs to the Datamate L-Tek line, known for rugged performance in harsh environments. It complements female sockets and cable assemblies within the same ecosystem. The model number indicates a male header with specific row count, position, and termination style, aligning with Harwin's standardized coding system for easy identification.

Replacement Considerations

Direct substitutes include other Harwin Datamate L-Tek male headers with identical 12-position, 2-row, 2.00mm pitch configurations. Verify that any alternative maintains the same pin-lock mechanism and shrouding style to ensure mechanical interchangeability without redesigning the host board footprint.
