Overview
The B5743-220-M-T-1 is a Datamate L-Tek series board connector manufactured by Harwin Inc. It features a male header configuration with 20 positions arranged in two rows. The component utilizes a 2.00 mm pitch and is designed for vertical through-hole mounting on printed circuit boards. Contact plating consists of gold on the mating interface and tin-lead on the tail, ensuring reliable electrical performance within specified operating temperatures.
Feature Summary
- Datamate L-Tek interconnect system providing secure pin-lock retention
- Shrouded four-wall housing design for precise alignment and protection
- Vertical orientation optimized for standard PCB assembly workflows
Applications
- Industrial control panel signal routing
- Test and measurement equipment internal connections
- General purpose electronic module interfacing
Procurement Notes
Verify compliance requirements as this specific part number contains lead. Confirm that the tin-lead contact finish aligns with target assembly processes and environmental regulations. Ensure the vertical form factor fits within the designated mechanical envelope without interference from adjacent components or enclosure structures during installation.
Selection Notes
Select this component when a high-density 20-position connection is required in a vertical orientation. The Datamate L-Tek system offers robust mechanical locking compared to standard headers. Consider the specific contact plating combination if harsh environments or specific soldering profiles are involved, noting the distinction between mating surface and termination finishes.
Part Context
This part belongs to the Datamate L-Tek family, known for its reliability in demanding applications. The B5743 prefix indicates a shrouded header variant. The 'M' denotes male contacts, while 'T' specifies the through-hole termination style. This series is widely used in sectors requiring durable, repeatable connections with minimal insertion force.
Replacement Considerations
Direct substitutes include other Harwin Datamate L-Tek headers with identical 20-pin counts and vertical mounting styles. Verify that any alternative maintains the same 2mm pitch and shrouded housing dimensions to ensure mechanical compatibility with existing mating sockets and PCB layouts.
