Overview
The B5743-220-M-L-3 is a Datamate L-Tek rectangular connector header manufactured by Harwin Inc. It features a 20-position configuration with male pins arranged in a dual-row layout. The component utilizes a 2.00mm (0.079 inch) pitch and is designed for right-angle through-hole mounting on printed circuit boards. This specific variant includes an L-shaped latch mechanism for secure mating. The housing is constructed from glass-reinforced polyester, rated UL94 V-0 for flammability.
Feature Summary
- Incorporates an L-shaped latch system to ensure positive retention during board-to-board or cable connections.
- Features a shrouded design that provides four-wall protection for the contact area.
- Utilizes a right-angle termination style suitable for vertical PCB integration.
Applications
- Industrial electronic equipment interconnects
- Board-to-board signal transmission
- Cable assembly termination
Procurement Notes
Verify the specific suffix 'L-3' against official datasheets to confirm the presence of the L-shaped latch and right-angle orientation. Ensure compatibility with corresponding female receptacles within the same Datamate series. Confirm RoHS compliance status as manufacturing specifications may vary by production batch.
Selection Notes
Select this component when a right-angle male header with a latching mechanism is required for a 20-position interface. The 2.00mm pitch dictates the footprint requirements on the target PCB. Verify that the mating counterpart supports the specific latch type to ensure mechanical stability.
Part Context
This part belongs to the Harwin Datamate L-Tek family, which is widely used in compact electronic designs. The B5743 prefix indicates a male pin header variant. The series is known for its robust mechanical locking features and high-density connectivity options in small form factors.
Replacement Considerations
M80-8672023 is a documented equivalent part number for this configuration. Cross-reference physical dimensions and latch mechanics before substitution.
