B5743-102-M-L-1

Overview

The B5743-102-M-L-1 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a single row with two positions and a 2 mm pitch. The component utilizes male pin contacts with gold plating for mating surfaces. Designed for through-hole mounting, it employs a solder pin termination style. The connector operates within a temperature range of -55°C to +125°C. Insulation is constructed from PBT material, while brass serves as the contact substrate.

Feature Summary

• Datamate L-Tek series design with shrouded housing
• Male pin configuration with selective gold plating
• Through-board mechanical mounting capability
• Latched connection mechanism

Applications

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

Procurement Notes

Verify RoHS compliance status and REACH SVHC details before procurement, as regulatory data may vary by production batch. Confirm that the specific ordering suffix matches the required latching and plating specifications. Ensure compatibility with corresponding female receptacles within the same Datamate L-Tek family to guarantee proper mechanical engagement and electrical continuity.

Selection Notes

Select this part for applications requiring a low-profile, two-position male header with secure latching. The 2 mm pitch suits dense board layouts. Verify that the through-hole termination method aligns with the PCB fabrication capabilities. Consider the operating temperature range and voltage ratings to ensure suitability for the target environment and circuit requirements.

Part Context

This component belongs to the Harwin Datamate L-Tek family, known for compact rectangular connectors. The B5743 prefix indicates a male header variant. It complements female receptacles like the B5740 series. The L-Tek line emphasizes high-density interconnect solutions for space-constrained industrial and consumer electronics designs.

Replacement Considerations

Cross-reference with M80-8670204 for equivalent specifications. Verify pin count, pitch, and mounting style match exactly. Ensure latching mechanisms are compatible with mating housings to maintain secure connection integrity during operation.
