Overview
The B5743-226-M-L-3 is a Datamate L-Tek series connector header manufactured by Harwin Inc. It features a 26-position configuration with a 2 mm (0.079 in) pitch across two rows. Designed for through-hole right-angle mounting, this male pin connector utilizes gold-plated phosphor bronze contacts and a black polyester insulation material rated UL94 V-0. The component operates within a temperature range of -55°C to +125°C and supports a rated voltage of 800V AC/DC with a current rating of 2.2A.
Feature Summary
- Right-angle through-hole mounting design for board-to-board or cable connections
- Gold-plated phosphor bronze contacts ensuring reliable signal transmission
- High-temperature resistant housing constructed from glass-reinforced polyester
Applications
- Board-to-board interconnections in electronic assemblies
- Wire-to-board connections requiring right-angle orientation
- Industrial control systems operating within specified thermal limits
Procurement Notes
Verify the specific suffix 'L-3' against official Harwin documentation to confirm right-angle orientation and termination style. Ensure compatibility with mating female sockets from the same Datamate L-Tek family. Check for RoHS compliance status as indicated in current datasheets, noting that older variants may differ. Confirm lead-free solder requirements if applicable to your assembly process.
Selection Notes
Select this component when a right-angle connection is required for space-constrained designs. The 26-position count suits applications needing moderate I/O density. Ensure PCB layout accommodates the right-angle profile and through-hole pad dimensions. Verify that the 2.2A current rating meets circuit demands without excessive heating.
Part Context
This part belongs to the Datamate L-Tek family, known for high-density interconnects. The B5743 prefix indicates a male header variant. The 'L' suffix typically denotes right-angle orientation, while '3' specifies the termination and packaging details. This series is widely used in compact electronic devices requiring robust mechanical locking.
Replacement Considerations
M80-8672622 is an equivalent part number for this component. Cross-reference with other Harwin Datamate headers only if pin count and pitch match exactly. Do not substitute with non-latching variants unless mechanical retention is not required.
