M50-4301045

Headers, Receptacles, Female Sockets Overview

The Harwin M50-4301045 is a 20-position, double-row board-to-board receptacle from the Archer M50 series. It features a 1.27 mm pitch and is designed for surface mount technology (SMT) installation. The connector utilizes gold-plated phosphor bronze contacts housed in black liquid crystal polymer (LCP). Rated for 1 kV voltage and 12 A current, it operates within a temperature range of -40°C to +105°C. This vertical socket provides reliable interconnection for high-density PCB applications.

Headers, Receptacles, Female Sockets Feature Summary

• High-voltage insulation capability up to 1kV for robust electrical isolation
• Gold-plated phosphor bronze contacts ensure low contact resistance and durability
• Liquid crystal polymer housing offers thermal stability and UL 94 V-0 flammability rating

Headers, Receptacles, Female Sockets Applications

• High-density board-to-board interconnections
• Industrial control systems requiring high voltage isolation
• Medical equipment internal circuitry
• Automotive electronics modules

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific manufacturer part number M50-4301045 against official Harwin documentation to confirm compatibility with your design requirements. Ensure that the surface mount footprint matches your PCB layout guidelines. Check for RoHS compliance status if required by your regulatory standards. Confirm that the 1.27 mm pitch aligns with mating header specifications.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a compact, high-current, and high-voltage board-to-board solution is needed. The 20-contact, double-row configuration suits space-constrained designs. Consider the SMT mounting style for automated assembly processes. Verify that the operating temperature range meets the environmental conditions of the target application.

Headers, Receptacles, Female Sockets Part Context

This receptacle belongs to the Archer M50 series, known for its fine-pitch connectivity solutions. The series supports various configurations including single and double rows with different contact counts. The M50-4301045 specifically addresses needs for vertical, surface-mounted connections with enhanced electrical ratings compared to standard low-voltage connectors.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same series include other M50 series receptacles with matching pitch and row count. Cross-referencing with Harwin's official replacement guide is recommended to ensure mechanical and electrical compatibility. Generic equivalents may not match the 1kV rating or LCP material properties.
