B5743-214-M-L-3

Overview

The Harwin B5743-214-M-L-3 is a Datamate L-Tek male header connector featuring a 14-position, dual-row configuration with a 2 mm pitch. Designed for through-hole mounting, it utilizes solder pin termination and gold-plated contacts to ensure reliable signal transmission. The shrouded housing provides four-wall protection, while the locking latch mechanism secures mating connections. It operates within a temperature range of -55°C to +125°C and supports voltages up to 800V AC/DC.

Feature Summary

• Four-wall shrouded housing design for enhanced contact alignment and protection
• Integrated locking latch system to secure mating engagement
• Gold-plated male pins for durable electrical connectivity
• Through-hole solder termination for robust PCB attachment

Applications

• Industrial control systems requiring secure interconnects
• Test and measurement equipment interfaces
• Automotive electronics assemblies
• Medical device internal wiring

Procurement Notes

Verify RoHS compliance status and REACH SVHC declarations prior to procurement, as environmental certifications may vary by production batch. Confirm that the specific suffix 'L-3' corresponds to the intended locking latch variant rather than standard or alternative latching mechanisms. Cross-reference the manufacturer's latest datasheet to ensure material specifications align with current regulatory requirements for the target application environment.

Selection Notes

Select this component when a high-density, dual-row male header with positive mechanical retention is required. The 2 mm pitch allows for compact board layouts while maintaining adequate spacing. Ensure the mating socket counterpart matches the Datamate L-Tek series specifications. Consider the through-hole footprint constraints and verify that the locking latch does not interfere with adjacent components or enclosure structures during assembly.

Part Context

This part belongs to the Harwin Datamate L-Tek family, a modular interconnect system known for its versatility in space-constrained applications. The B5743 series specifically denotes male headers designed for vertical board-to-board or cable connections. The L-Tek line emphasizes durability and ease of use, making it suitable for demanding environments where vibration resistance and reliable contact are critical performance factors.

Replacement Considerations

The M80-8671422 is listed as an alias for the B5743-214-M-T-1 variant; however, direct substitution requires verifying that the locking latch specification (L-3) matches the original design intent. Generic 2 mm pitch headers lack the integrated latch and four-wall shroud, potentially compromising mechanical stability. Always confirm dimensional compatibility and electrical ratings before replacing.
