B5743-107-M-T-1

Overview

The Harwin B5743-107-M-T-1 is a Datamate L-Tek series header connector featuring 7 male positions in a vertical right-angle configuration. It utilizes a 2.00mm pitch with a pin lock securing mechanism and shrouded four-wall design. The contacts are gold-plated phosphor bronze, rated for 2.2A current and 800VAC/DC voltage. Designed for through-hole solder termination, the unit operates within a -55°C to +125°C temperature range using UL94 V-0 rated polyester insulation.

Feature Summary

• Vertical right-angle board-to-board or cable connection style
• Pin lock securing mechanism prevents accidental disengagement
• Shrouded four-wall housing ensures precise alignment during mating

Applications

• Board-to-board interconnections in compact electronic assemblies
• Wire-to-board connections requiring right-angle routing
• Industrial control modules operating in high-temperature environments

Procurement Notes

Verify that the specific part number matches the required seven-position count and right-angle orientation. Confirm that the manufacturer is Harwin Inc. and that the component belongs to the Datamate L-Tek series. Ensure compatibility with mating female connectors from the same family. Check for any recent product change notifications regarding material specifications or manufacturing origin updates.

Selection Notes

Select this component when a low-profile vertical interconnect is required for signal transmission. The right-angle design facilitates space-constrained layouts where straight headers would exceed board boundaries. The pin lock feature provides mechanical stability against vibration. Verify that the circuit requirements do not exceed the 2.2A current rating or 800V voltage limit specified for this connector type.

Part Context

This connector belongs to the Datamate L-Tek family, known for high-density interconnect solutions. The series offers various pin counts and configurations to support diverse electronic applications. The B5743 designation indicates a male header variant within this standardized ecosystem, ensuring interoperability with other components in the same product line.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek headers with matching seven-pin counts and right-angle orientations. Ensure replacement parts maintain the same 2.00mm pitch and pin lock mechanism for direct interchangeability without PCB redesign.
