B5741-204-F-N-2

Overview

The B5741-204-F-N-2 is a 20-position female receptacle connector from the Harwin Datamate L-Tek series. It features a dual-row layout with a 2.00mm (0.079 inch) pin spacing. The unit utilizes solder pin termination for PCB mounting and employs gold-plated contacts to ensure reliable signal transmission. Designed for discrete wire applications, it supports wire gauges ranging from 28 AWG to 24 AWG. The housing is constructed from black PBT material rated UL94V-0 for flammability, providing durability in electronic assemblies requiring secure board-level interconnections.

Feature Summary

• Dual-row female socket configuration for high-density circuit board integration
• Solder pin termination style ensures stable mechanical attachment to printed circuit boards
• Gold-plated brass contacts provide corrosion resistance and low contact impedance
• UL94V-0 rated PBT housing offers thermal stability and fire safety compliance

Applications

• Industrial control system interface modules
• Automotive electronics sensor connections
• Telecommunications equipment backplanes
• Medical device internal wiring harnesses

Procurement Notes

Verify that the specific suffix 'N' corresponds to the intended solder pin variant rather than IDC or crimp styles when sourcing replacements. Confirm that the 20-position count matches the target design footprint. Ensure compatibility with mating plugs from the same Datamate L-Tek family to maintain proper alignment and latch engagement during assembly processes.

Selection Notes

Select this component when a rigid PCB-mounted solution is required instead of free-hanging cable connectors. The solder pin termination necessitates surface mount or through-hole manufacturing capabilities. Consider the 2.00mm pitch constraints against available board space. Validate that the operating temperature range aligns with the environmental conditions of the final product deployment scenario.

Part Context

This part belongs to the Datamate L-Tek family, which specializes in high-reliability interconnect solutions. Unlike the Mix-Tek series, L-Tek focuses on robust board-to-board or board-to-wire connections using standardized form factors. The B5741 prefix typically denotes specific housing variations within this ecosystem, ensuring interchangeability with other components sharing the same pitch and row configuration standards.

Replacement Considerations

M80-8882005 serves as a parameter-equivalent alternative within the Harwin portfolio. Verify that the replacement maintains identical solder pin termination and dual-row geometry. Cross-reference the mating plug requirements to ensure mechanical compatibility before substituting the original component in existing designs.
