General purpose electronic interconnects

Procurement Notes

Verify the specific suffix 'W' against official Harwin documentation to confirm material or coating variations. Ensure compatibility with mating female sockets in the same Datamate L-Tek family. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into regulated products.

Selection Notes

Select this component for applications requiring a compact, low-profile connection with high reliability. The 2 mm pitch allows for dense board layouts. Verify that the mating counterpart matches the pin count and row configuration. Consider thermal requirements when operating near the maximum temperature limit.

Part Context

This part belongs to the Datamate L-Tek family, known for its robust mechanical locking and small form factor. The B5743 prefix typically denotes male headers in this series. It serves as a critical interface element in modern electronics where space constraints and signal integrity are paramount.
