B5743-210-M-T-0

Overview

The B5743-210-M-T-0 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a vertical through-hole mounting style with 10 positions arranged in a dual row configuration. The connector utilizes a 2 mm (0.079 inch) pitch and includes male pin contacts with gold plating for reliable signal transmission. Designed for board-to-board or cable applications, it operates within a temperature range of -55°C to +125°C. The housing is constructed from black polyester reinforced with glass fiber, meeting UL94 V-0 flammability standards.

Feature Summary

• Dual-row shrouded design provides four-wall shielding for secure mating
• Gold-plated male pins ensure durable electrical connectivity
• Vertical through-hole termination facilitates standard PCB assembly

Applications

• Board-to-board interconnections
• Cable-to-board connections
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific suffix designation against current manufacturer catalogs, as suffix variations may indicate differences in contact plating, packaging, or compliance status. Confirm RoHS and REACH compliance requirements prior to procurement. Check for any product change notifications that might affect material specifications or manufacturing origin. Ensure compatibility with mating sockets from the same Datamate L-Tek series.

Selection Notes

Select this component when a 10-position dual-row male header is required for vertical PCB mounting. The 2mm pitch suits applications needing moderate density without excessive board space consumption. Consider the operating temperature range and voltage ratings to ensure suitability for the target environment. Verify that the mating socket counterpart matches the small bore or standard bore specification defined by the series.

Part Context

This part belongs to the Datamate L-Tek series, designed to meet British Standard 9525-F0033. The series offers high-density interconnect solutions with robust mechanical locking mechanisms. The B5743 prefix typically denotes male headers in this family, providing versatile options for various electronic assemblies requiring reliable signal and power distribution.

Replacement Considerations

M80-8671022 is an equivalent part number for this component. Verify dimensional tolerances and mating interface compatibility before substitution. Ensure that any replacement maintains the same pitch, row count, and contact gender to preserve system integrity.
