B5743-103-M-L-1

Overview

The B5743-103-M-L-1 is a Datamate L-Tek male pin header manufactured by Harwin Inc. It features a 2 mm pitch and a single row configuration with three positions. The connector utilizes through-hole solder termination for board mounting. Contact surfaces are gold-plated, while posts feature tin-lead plating with a nickel barrier. The unit operates within a temperature range of -55°C to +125°C.

Feature Summary

Datamate L-Tek series design with shrouded housing
Male pin contact type for secure mating
Through-hole solder termination method
Gold-plated contact surfaces for conductivity

Applications

General purpose board-to-board interconnects
Cable assemblies requiring male pin headers
Electronic modules needing reliable signal paths

Procurement Notes

Verify the specific suffix 'L' in the part number against official Harwin documentation to confirm single-row configuration and pin count. Ensure compatibility with mating female sockets from the same Datamate L-Tek family. Confirm RoHS compliance status and lead-free requirements if applicable to your assembly process before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, single-row male header is required for tight space constraints. The 2 mm pitch offers a balance between density and ease of handling. Consider the through-hole installation method for robust mechanical stability compared to surface mount alternatives. Verify that the mating interface supports the specific latch mechanism associated with the L-Tek series.

Part Context

This part belongs to the Datamate L-Tek family, known for compact rectangular connectors. It serves as a male counterpart to female wire housings or board sockets. The model specifies a three-position variant, distinguishing it from higher-count versions like the B5743-214-M-T-1. It is designed for applications prioritizing small form factors and reliable electrical connections.
