M50-3123645

Headers, Receptacles, Female Sockets Overview

The Harwin M50-3123645 is a 72-position (36+36) dual in-line socket assembly from the Archer M50 series. It features a 1.27 mm pitch and two rows of contacts designed for surface mount technology (SMT). The connector utilizes vertical orientation with gold-plated brass contacts to ensure reliable signal transmission. Rated for 1A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black thermoplastic material compliant with UL 94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Vertical surface mount design for automated PCB assembly
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Thermoplastic housing with UL 94 V-0 flammability rating

Headers, Receptacles, Female Sockets Applications

• Wire-to-board interconnections
• Board-to-board connections
• High-density electronic assemblies requiring SMT compatibility

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact finish thickness, identified as flash plating in available documentation, against strict application requirements. Confirm moisture sensitivity level (MSL) classification prior to reflow soldering processes. Ensure ordering suffixes match the required tube packaging format. Cross-reference the 1.27 mm pitch and 72-position count to prevent mating errors with incompatible header counterparts.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when high-density vertical interconnects are required for board-to-board or wire-to-board applications. The 1.27 mm pitch allows for compact layouts while maintaining 1A current capacity per contact. Consider the SMT mounting style for automated production lines. Verify that the operating temperature range of -40°C to +105°C meets environmental constraints.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin Archer M50 series, which specializes in high-density interconnect solutions. The series offers various configurations including headers, sockets, and IDC connectors. The M50-3123645 specifically addresses the need for robust, surface-mountable socket assemblies with precise alignment features for reliable mating.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must maintain the 1.27 mm pitch, 72-position count, and vertical SMT form factor. Compatible alternatives include other Harwin M50 series socket variants with matching pin counts. Generic replacements require verification of contact geometry and housing dimensions to ensure proper fit.
