M50-3102045R

Headers, Receptacles, Female Sockets Overview

The M50-3102045R is a surface-mount header from the Harwin ARCHER series, featuring a 1.27 mm (0.05 in) pitch and 2x20 positions. It utilizes gold-plated phosphor bronze contacts with a 3 mm mating pin length. The connector operates between -40°C and +105°C, rated for 1 A current and 300 V voltage. Constructed with LCP housing and UL 94 V-0 flammability rating, it offers 1 GOhm insulation resistance. Packaged in reels or cut tape, this straight-mount receptacle ensures reliable high-density interconnections.

Headers, Receptacles, Female Sockets Feature Summary

• Gold-plated phosphor bronze contacts ensure low contact resistance and corrosion resistance for reliable signal transmission.
• LCP housing material provides high thermal stability and meets UL 94 V-0 flammability standards.
• Surface-mount design with mounting pegs facilitates precise PCB alignment and secure mechanical fixation during assembly.

Headers, Receptacles, Female Sockets Applications

• High-density board-to-board interconnects
• Industrial control systems requiring robust SMT headers
• Automotive electronics modules

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'R' confirms reel packaging configuration against official Harwin documentation. Ensure compatibility with standard reflow soldering profiles for lead-free processes. Confirm that the 1.27 mm pitch aligns with the target PCB footprint design rules. Cross-reference the gold plating thickness requirements if extreme wear resistance is necessary for repeated mating cycles.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 2-row, 40-position SMT header with 1.27 mm spacing is required. The gold plating on phosphor bronze contacts suits applications demanding superior conductivity and durability. The LCP housing supports high-temperature environments up to 105°C. Consider the straight orientation and mounting pegs for stable surface-mount placement without additional mechanical fasteners.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin ARCHER M50 series, designed for high-reliability electronic assemblies. The series emphasizes compact form factors with robust mechanical retention features like mounting pegs. The M50-3102045R specifically addresses needs for dense, surface-mounted connections in space-constrained industrial and automotive applications.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same ARCHER family include M50-3102042 (tube packaging) or M50-3102045 (reel packaging). Verify that alternative part numbers maintain identical pitch, row count, and contact plating specifications to ensure functional interchangeability.
