B5743-104-M-T-1

Overview

The B5743-104-M-T-1 is a male pin header from the Harwin Datamate L-Tek series, designed for vertical through-hole mounting. It features a 2-row configuration with 4 positions and a 2.00mm (0.079 inch) contact pitch. The connector utilizes gold-plated phosphor bronze contacts with a 29.5µin mating finish and tin-lead post plating. Rated for 800VAC/DC and 2.2A, it operates within a temperature range of -55°C to 125°C. The housing is black, UL94 V-0 rated polyester reinforced with glass fiber, providing a shrouded design with pin-locking retention.

Feature Summary

• Vertical through-hole mounting style with pin-locking retention mechanism
• Shrouded housing constructed from black UL94 V-0 rated glass-reinforced polyester
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission

Applications

• Board-to-board interconnections requiring secure mechanical locking
• Cable-to-board connections in industrial control systems
• Compact electronic assemblies needing high-density vertical headers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with mating sockets and assembly requirements. Confirm that the tin-lead post plating meets project specifications, as lead-free alternatives may exist in other variants. Cross-reference the part number with official distributor databases to validate current availability status and manufacturing lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when a low-profile, vertically oriented male header with positive locking is required. The 2.00mm pitch allows for dense circuit board layouts while maintaining adequate spacing. Ensure mating connectors belong to the same Datamate L-Tek family to guarantee proper alignment and electrical continuity. Consider the operating temperature range and voltage rating to match the environmental conditions of the target application.

Part Context

This part belongs to the Datamate L-Tek series, known for its robust pin-locking feature that prevents accidental disconnection. The series offers various row counts and positions to suit different connectivity needs. As a male header, it serves as the counterpart to female sockets, forming complete interconnect solutions for Harwin's modular connector ecosystem.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek male headers with matching 2-row, 4-position configurations and 2.00mm pitch. Verify that any replacement maintains the same vertical orientation, through-hole termination, and pin-locking functionality to ensure mechanical and electrical interchangeability.
