B5743-104-M-T-R

Overview

The B5743-104-M-T-R is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 4-position configuration with a 2.00mm (0.079 inch) pin-to-pin spacing across two rows. Designed for vertical through-hole mounting, the contacts utilize gold plating on the mating surfaces and tin-lead plating on the posts. The housing is constructed from black polyester reinforced with glass fiber, rated UL94 V-0 for flammability. This component supports board-to-board or cable applications within an operating temperature range of -55°C to +125°C.

Feature Summary

• Vertical through-hole mounting style for secure PCB integration
• Four-wall shrouded design providing mechanical protection and alignment
• Gold-plated contact surfaces ensuring reliable signal transmission
• High-temperature resistant polyester-glass composite insulation

Applications

• Board-to-board interconnect systems
• Cable-to-board wiring assemblies
• Industrial control panel connections
• Embedded electronic module interfaces

Procurement Notes

Verify that the specific suffix 'R' corresponds to the required reel packaging format rather than standard tube quantities. Confirm the tin-lead post plating meets project material specifications. Ensure the four-row shroud geometry matches the mating socket requirements. Validate the UL94 V-0 rating against environmental safety standards.

Selection Notes

Select this model when a compact 4-position male header is required for vertical assembly. The 2.00mm pitch accommodates standard trace widths while maintaining robust mechanical stability. Consider the through-hole termination method for superior durability compared to surface mount alternatives in high-vibration environments.

Part Context

This component belongs to the Datamate L-Tek series, characterized by its small bore female sockets and versatile mounting options. The B5743 prefix indicates a male header variant within the broader Harwin interconnect portfolio. It complements female counterparts like the B5740 series for complete system connectivity solutions.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek male headers with identical 4-position counts and 2.00mm pitch. Verify mechanical compatibility with existing mating sockets before substitution.
