B5743-220-M-L-1

Overview

The B5743-220-M-L-1 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a 20-position, dual-row configuration with a 2mm (0.079 inch) pin-to-pin spacing. Designed for vertical through-hole mounting, this component utilizes male pins housed in a shrouded plastic body. The connector supports wire-to-board or board-to-board interconnections within the specified electrical and thermal operating ranges.

Feature Summary

• Vertical through-hole mounting style for secure PCB integration
• Shrouded housing design to ensure proper mating alignment
• Dual-row layout accommodating 20 positions in a compact footprint

Applications

• Wire-to-board interconnection systems
• Board-to-board signal transmission
• General purpose electronic device assembly

Procurement Notes

Verify the specific suffix 'L' against official Harwin documentation to confirm female contact specifications, as some sources may list conflicting gender data. Ensure the selected variant matches the required small bore terminal compatibility. Cross-reference the RoHS status and REACH compliance requirements with the current manufacturer datasheet before finalizing procurement orders.

Selection Notes

Select this connector when a 20-position, 2mm pitch vertical header is required. Confirm that the mating counterpart is compatible with the Datamate L-Tek series standards. Evaluate the mechanical constraints of the application to ensure the vertical profile fits within the enclosure limits. Verify that the circuit current requirements fall within the connector's rated capacity.

Part Context

This component belongs to the Datamate L-Tek family, which is characterized by its robust locking mechanism and high-density interconnect capabilities. The series is widely used in industrial and consumer electronics where reliable connections are critical. The B5743 prefix indicates a specific header configuration within this extensive product line.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek headers with matching 20-position counts and 2mm pitch. Ensure any replacement maintains the same vertical orientation and shrouded design to preserve mating integrity.
