Overview
The B5743-204-M-T-U is a Datamate L-Tek series board connector manufactured by Harwin Inc. It features a vertical male header configuration with four positions arranged in two rows. The component utilizes a 2 mm pitch and is designed for through-hole mounting on printed circuit boards. The housing material is polyester reinforced with glass fill, providing structural integrity and high-temperature resistance. Contact termination is achieved via solder pins, ensuring reliable electrical connections within the specified operating temperature range of -55°C to +125°C.
Feature Summary
- Vertical male pin header design for direct board-to-board or cable mating applications
- Dual-row configuration with secure latching mechanism for stable connection retention
- High-temperature resistant housing constructed from glass-filled polyester material
Applications
- Industrial control system interconnections
- Consumer electronics assembly
- Automotive electronic modules
Procurement Notes
Verify that the specific suffix T-U corresponds to the required vertical orientation and tube packaging format. Confirm compatibility with mating sockets from the same Datamate L-Tek family. Ensure the through-hole footprint matches the target PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this part when a low-profile, vertical male header is required for compact designs. The dual-row arrangement maximizes contact density within a limited board area. Consider the thermal stability of the glass-filled insulation if the application involves elevated ambient temperatures or reflow soldering processes.
Part Context
This component belongs to the Datamate L-Tek product line, which is characterized by its robust mechanical locking systems and high reliability standards. The series offers various row counts and termination styles to accommodate diverse connectivity needs in demanding environments.
Replacement Considerations
Substitutes such as B5743-204-M-T-W or B5743-204-M-T-A may be considered if they match the required pin count and mounting style. Verify that any alternative maintains the same 2 mm pitch and dual-row geometry to ensure physical compatibility.
