Overview
The B5743-220-M-T-V is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 2x10 pin configuration with a 2.00mm pitch and vertical through-hole termination. The contacts are gold-plated for reliable signal transmission, while the housing is constructed from glass-filled polybutylene terephthalate (PBT) rated UL94 V-0. This shrouded, double-row connector is designed for board-to-board or cable applications, offering a secure mating interface within the standard Datamate series specifications.
Feature Summary
- Vertical through-hole mounting style for direct PCB integration
- Gold-plated male pins ensuring durable electrical connectivity
- Shrouded design with four-wall protection for alignment
- High-temperature resistant PBT insulation material
Applications
- Industrial control system interconnects
- Automotive electronic module connections
- Telecommunications equipment backplanes
- Medical device internal circuitry
Procurement Notes
Verify the specific suffix 'V' against the official Harwin datasheet to confirm exact contact plating thickness and housing latch variations. Ensure compatibility with mating female connectors in the same Datamate L-Tek series. Check for RoHS compliance status and REACH SVHC declarations prior to final procurement approval.
Selection Notes
Select this component when a vertical, shrouded male header with 20 positions is required. Confirm that the 2.00mm pitch matches the target PCB footprint. Verify that the operating temperature range of -55°C to +125°C meets the environmental requirements of the end application.
Part Context
This part belongs to the Datamate L-Tek family, known for high-density interconnect solutions. The B5743 prefix indicates a male plug connector. The '220' denotes the 2x10 position count. The 'T' signifies through-hole solder termination, and 'M' indicates male contact gender.
Replacement Considerations
Compatible substitutes include other Harwin Datamate L-Tek male headers with identical 2x10 positioning and vertical orientation. Cross-reference part numbers such as B5743-220-M-T-0 or B5743-220-M-T-1 if the specific 'V' variant is unavailable, ensuring mechanical and electrical parameters match.
