Overview
The B5743-226-M-L-1 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a 26-position, dual-row configuration with a 2mm pitch. The component utilizes male pin contacts with gold plating for mating surfaces and tin-lead plating on posts. Designed for through-hole solder termination, it operates within a temperature range of -55°C to +125°C. The housing is constructed from glass-filled polyester rated UL94 V-0. Rated voltage is 800VAC/DC with a current capacity of 2.2A.
Feature Summary
- Datamate L-Tek series interconnect system
- Dual-row shrouded header design
- Pin lock securing mechanism
- Gold-plated contact interface
Applications
- Board-to-board connections
- Cable-to-board assemblies
- Industrial control systems
- Test and measurement equipment
Procurement Notes
Verify the specific suffix 'L' against official Harwin documentation to confirm small bore compatibility. Ensure the tin-lead post plating meets project environmental compliance requirements. Confirm that the 2.2A rating aligns with thermal management capabilities in the final assembly. Cross-reference the datasheet for precise stacking height dimensions required by the mechanical enclosure.
Selection Notes
Select this component when a high-density, secure board-to-board connection is required. The pin lock feature provides robust retention compared to friction-fit alternatives. The dual-row layout maximizes I/O density within a limited footprint. Verify that the through-hole mounting style suits the PCB fabrication process and available real estate.
Part Context
This part belongs to the Datamate L-Tek family, which offers modular rectangular connectors. The B5743 prefix indicates a male header variant. The model number encodes position count, row configuration, and plating specifications. It serves as a critical interface element in complex electronic assemblies requiring reliable signal transmission.
Replacement Considerations
M80-8882622 is a confirmed alternate part number for this component. Verify mechanical fit and electrical parameters before substitution. Ensure the replacement maintains the same locking mechanism and plating specifications.
