Overview
The B5741-204-F-T-0 is a Datamate L-Tek series female receptacle connector manufactured by Harwin. It features a 4-position layout arranged in a dual-row configuration with a 2 mm (0.079 inch) pitch. The contacts are gold-plated sockets designed for crimp termination, supporting wire gauges from 28 AWG to 24 AWG. This through-hole component utilizes a vertical mounting style suitable for cable or board-to-board connections. It operates within a temperature range of -55°C to +125°C and weighs approximately 3.417 grams.
Feature Summary
- Double-row vertical receptacle design for compact space utilization
- Gold-plated contact surfaces ensure reliable signal transmission
- Crimp termination method supports standard wire gauge ranges
Applications
- Board-to-board interconnections
- Cable assembly terminations
- Electronic device internal wiring
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal type and plating specifications. Ensure compatibility with mating pins and housing components within the Datamate L-Tek ecosystem. Cross-reference part numbers such as M80-8883405 if alternative sourcing is required. Confirm RoHS and REACH compliance status directly with the supplier documentation prior to procurement.
Selection Notes
Select this component when a low-profile, double-row female connector is required for tight spatial constraints. The 2 mm pitch allows for high density while maintaining robust mechanical stability. Verify that the application environment falls within the specified -55°C to +125°C operating range. Ensure the wire gauge matches the 24-28 AWG requirement for proper crimping performance.
Part Context
This part belongs to the Harwin Datamate L-Tek family, known for its small form factor and high reliability. The B5741 series specifically denotes vertical through-hole receptacles. Similar variants exist with different pin counts and termination styles, but this model is distinct due to its 4-position dual-row configuration and specific gold plating finish.
Replacement Considerations
Direct substitutes may include other Harwin Datamate L-Tek receptacles with identical pin counts and row configurations. Verify mechanical dimensions and electrical ratings before substitution. Generic connectors with similar pitch may not offer equivalent locking mechanisms or durability standards.
