B5743-220-M-T-W

Overview

The B5743-220-M-T-W is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a 20-position, two-row male pin configuration with a 2.00mm (0.079 inch) pitch. Designed for through-hole vertical mounting, this shrouded connector utilizes gold-plated phosphor bronze contacts to ensure reliable signal transmission. The housing is constructed from black polyester reinforced with glass fiber, meeting UL94 V-0 flammability standards. It supports a rated current of 2.2A and withstands voltages up to 800V AC/DC across an operating temperature range of -55°C to +125°C.

Feature Summary

• Datamate L-Tek series interconnect system providing robust board-to-board or cable connections
• Shrouded four-wall design ensures precise alignment and protection during mating
• Gold-plated phosphor bronze contacts offer high conductivity and corrosion resistance
• Vertical through-hole termination facilitates standard PCB assembly processes

Applications

• Industrial control systems requiring durable interconnect solutions
• Test and measurement equipment needing stable signal paths
• Automotive electronics applications within specified temperature ranges
• Medical device instrumentation requiring reliable board connections

Procurement Notes

Verify the specific suffix 'W' against official Harwin documentation to confirm orientation and locking mechanism details. Ensure compatibility with corresponding female housings in the same Datamate L-Tek series. Check for RoHS compliance status as regulatory requirements may vary by region and production batch. Confirm that the vertical form factor aligns with available board space constraints.

Selection Notes

Select this component when a 20-position vertical header is required for high-reliability applications. The 2.00mm pitch allows for dense circuit layouts while maintaining adequate spacing. Consider the shrouded design for environments where misalignment risks exist. Evaluate the thermal and electrical ratings against system demands to ensure long-term operational stability under load conditions.

Part Context

This part belongs to the Datamate L-Tek family, known for its modular design and interchangeability. The B5743 prefix indicates a specific header variant within Harwin's rectangular connector portfolio. Similar parts like B5743-220-M-T-1 differ primarily in contact plating or orientation, offering flexibility for diverse manufacturing needs while maintaining consistent mechanical interfaces.

Replacement Considerations

Direct substitutes include other Harwin Datamate L-Tek headers with matching 20-position counts and 2.00mm pitch. Verify that alternative parts maintain identical shrouding and mounting styles to preserve mechanical integrity. Cross-reference datasheets to ensure equivalent electrical ratings and material compositions before implementation.
