B5743-102-M-T-A

Overview

The B5743-102-M-T-A is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a vertical through-hole mounting style with two positions arranged in a single row. The connector utilizes a 2.00mm (0.079 inch) contact pitch and includes pin locking for secure mating. Contacts are gold-plated, and the housing is constructed from black PBT material rated UL94 V-0. It operates within a temperature range of -55°C to +125°C and supports a rated voltage of 800VAC/DC.

Feature Summary

• Datamate L-Tek series design with pin locking mechanism
• Vertical through-hole termination for PCB integration
• Gold-plated contacts on phosphor bronze base material
• UL94 V-0 rated black PBT insulation housing

Applications

• Board-to-board interconnections
• Cable-to-board connections
• General purpose electronic assemblies requiring secure latching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required contact plating thickness and housing color options. Confirm that the pin locking feature aligns with the mechanical constraints of the target assembly. Check for any recent product change notifications regarding material composition or manufacturing location updates before finalizing procurement specifications.

Selection Notes

Select this component when a low-profile, vertically mounted male header with positive retention is required. The 2mm pitch suits dense circuit layouts. Ensure the mating female connector belongs to the same Datamate L-Tek family to guarantee correct alignment and electrical continuity. Consider the thermal rating if operating near the upper limit of the specified temperature range.

Part Context

This part belongs to the Datamate L-Tek family, characterized by its robust pin-locking system and compact form factor. It serves as a male counterpart to female receptacles within the same series. The model number indicates a 2-position variant with standard through-hole termination and specific housing characteristics defined by the suffix codes.

Replacement Considerations

Direct substitutes include other Harwin B5743 series headers with identical position counts and locking mechanisms. Verify that alternative parts maintain the same 2mm pitch and vertical orientation. Cross-compatibility with non-Harwin connectors is not guaranteed due to unique locking geometry.
