B5743-103-M-T-A

Overview

The B5743-103-M-T-A is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 2.00mm pitch and three positions in a single row configuration. The component utilizes gold-plated phosphor bronze contacts with a polyester, glass-filled insulation housing rated UL94 V-0 for high-temperature stability. Designed for through-hole vertical mounting, it employs a pin-lock securing mechanism to ensure reliable board-to-board or cable connections.

Feature Summary

• Single-row male pin configuration with secure latching mechanism
• High-temperature resistant UL 94V-0 housing material
• Gold-plated phosphor bronze contacts for reliable conductivity

Applications

• Board-to-board interconnects requiring secure latching
• Cable-to-board connections using single-row headers
• High-temperature electronic assemblies

Procurement Notes

Verify the specific suffix 'A' against official Harwin documentation to confirm exact mechanical dimensions and locking style, as variations exist within the B5743 series. Ensure compatibility with mating female sockets from the same Datamate L-Tek family. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a single-row, vertically mounted male header with a pitch of 2.00mm is required. The choice is driven by the need for a pin-lock securing method rather than jackscrew fixation. Consider the UL 94V-0 rating if the application involves elevated operating temperatures. Verify that the three-position count matches the circuit design requirements.

Part Context

This part belongs to the Datamate L-Tek series, which offers compact interconnect solutions. The B5743 prefix indicates a male header variant. While similar models like B5743-103-M-T-1 exist, the '-A' suffix denotes specific mechanical or packaging attributes defined by Harwin. This series supports both single and double-row configurations with varying position counts.

Replacement Considerations

Direct substitutes include other Harwin Datamate L-Tek male headers with identical 2.00mm pitch and single-row layout. Models such as B5743-103-M-T-1 may serve as alternatives if mechanical locking differences are acceptable. Always verify mating compatibility with corresponding female receptacles before substitution.
