Overview
The B5743-226-M-T-U is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a 2 mm pitch with 26 positions arranged in two rows. The component utilizes male pin contacts with tin plating and is designed for through-hole vertical mounting. The housing is constructed from black thermoplastic material rated UL 94V-0 for high-temperature resistance. This board connector supports a current rating of 2.2A and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Secure latching mechanism ensures reliable connection integrity
- High-temperature resistant UL 94V-0 housing material
- Vertical through-hole mounting configuration
- Dual-row layout for compact circuit board integration
Applications
- Industrial control systems requiring robust interconnects
- Automotive electronics assemblies
- Telecommunications equipment hardware
- General purpose board-to-board connections
Procurement Notes
Verify the specific suffix T-U against official Harwin documentation to confirm contact finish and housing material specifications. Ensure compatibility with mating wire housings within the Datamate L-Tek series. Confirm RoHS compliance status as required by project regulations before final procurement authorization.
Selection Notes
Select this component for applications demanding secure latching and high thermal stability. The 2 mm pitch allows for dense pin arrangements while maintaining electrical isolation. Verify that the through-hole footprint matches the target PCB design constraints and that the 2.2A current rating meets system power requirements.
Part Context
This part belongs to the Datamate L-Tek family, known for its modular design and secure locking mechanisms. The series offers various configurations including single and double-row options with different mounting styles. The B5743 variant specifically denotes headers with latching features suitable for vibration-prone environments.
Replacement Considerations
Cross-reference with other Harwin B5743 series variants such as B5743-226-M-L-1 or B5743-226-M-L-3 for alternative contact finishes or mounting angles. Ensure mechanical dimensions and electrical ratings remain compatible when substituting components.
