B5743-226-M-L-0

Overview

The B5743-226-M-L-0 is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 26-position configuration with a 2 mm (0.079 in) pitch across two rows. The component utilizes a right-angle through-hole mounting style with solder pin termination. Contact surfaces are gold-plated, and the housing is constructed from black glass-filled polyester rated UL94 V-0. It operates within a temperature range of -55°C to +125°C and supports a maximum voltage of 120V AC/DC.

Feature Summary

• Right-angle shrouded design for compact board-to-board or cable interconnections
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Integrated latch mechanism provides secure mating retention
• High-temperature resistant insulation material suitable for demanding environments

Applications

• Industrial control systems requiring robust vertical interconnects
• Communication equipment utilizing high-density signal routing
• Automotive electronics modules needing secure latching headers
• Test and measurement instrumentation interfaces

Procurement Notes

Verify RoHS compliance status and REACH SVHC declarations prior to procurement, as environmental certifications may vary by production batch. Confirm that the specific suffix indicates the correct right-angle orientation and latch type. Ensure compatibility with mating sockets from the same Datamate L-Tek series. Check for any recent product change notifications regarding material substitutions or manufacturing origin updates.

Selection Notes

Select this part when a right-angle male header with a latching feature is required for 26-position connections. The 2 mm pitch allows for dense circuit board layouts. Verify that the PCB footprint accommodates the right-angle solder pins and the physical height of the shrouded housing. Ensure the mating connector belongs to the compatible female counterpart series to guarantee proper mechanical engagement and electrical continuity.

Part Context

This component belongs to the Datamate L-Tek family, designed for high-reliability applications. The B5743 prefix denotes a male header variant. The 'L' suffix typically indicates a latched version, while '0' specifies the right-angle configuration. This series is widely used in industrial and automotive sectors where vibration resistance and secure connection integrity are critical operational requirements.

Replacement Considerations

Direct substitutes include other Harwin Datamate L-Tek male headers with identical 26-position count, 2 mm pitch, right-angle orientation, and latching mechanisms. Cross-reference part numbers such as M80-8672622 for equivalent specifications. Ensure replacement units maintain the same contact plating thickness and insulation material ratings to preserve performance standards.
