B5743-103-M-T-1

Overview

The Harwin B5743-103-M-T-1 is a Datamate L-Tek male header connector featuring three positions in a single-row configuration. It utilizes a 2mm pitch and employs vertical through-hole solder pin termination for secure board attachment. The component incorporates gold-plated contacts to ensure reliable signal transmission within electronic assemblies.

Feature Summary

• Single-row male pin configuration with shrouded design
• Vertical through-hole solder termination style
• Gold-plated contact finish for conductivity

Applications

• General purpose board-to-board interconnects
• Cable-to-board connections
• Low voltage signal routing in compact electronics

Procurement Notes

Verify the specific suffix against official Harwin documentation to confirm exact row count and termination type, as variations exist within the B5743 series. Ensure compatibility with mating receptacles from the same Datamate L-Tek family. Confirm RoHS compliance status via the manufacturer datasheet prior to integration into regulated products.

Selection Notes

Select this part when a low-profile, single-row male header is required for space-constrained designs. The 2mm pitch offers a balance between density and ease of assembly. Verify that the operating temperature range of -55°C to 125°C meets environmental requirements for the target application.

Part Context

This component belongs to the Harwin Datamate L-Tek series, known for high-density rectangular connectors. The B5743 prefix typically denotes male headers with specific latching or fixing mechanisms. This specific model represents a standard vertical through-hole variant within that extensive product line.

Replacement Considerations

Cross-reference with M80-8670302 if available. Verify mechanical dimensions and electrical ratings match exactly before substitution.
