M22-7140942

Headers, Receptacles, Female Sockets Overview

The M22-7140942 is a dual-in-line vertical socket assembly from the Harwin M22 series, designed for board-to-board interconnections. It features 18 positions (9+9) with a 2.00mm pitch and through-hole termination. The connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the tail, rated for 1A current and 500V voltage. Constructed with black nylon insulation, it operates within a temperature range of -25°C to +105°C and meets UL94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Dual-in-line configuration providing 18 positions in a compact vertical format
• Mixed contact plating combining gold for reliable signal transmission and tin for cost-effective termination
• Through-hole mounting style ensuring secure PCB attachment
• High-temperature resistant nylon housing suitable for standard reflow processes

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnects in industrial control systems
• Signal routing in telecommunications equipment
• Internal connections within consumer electronics assemblies

Headers, Receptacles, Female Sockets Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm that the mixed gold-tin plating specification matches design requirements for both signal integrity and soldering compatibility. Ensure storage conditions prevent oxidation of exposed tin surfaces prior to assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this part when a vertical dual-row receptacle is required for space-constrained designs. The 2.00mm pitch allows for higher density compared to traditional 2.54mm headers. Consider the mixed plating option if budget constraints exist while maintaining critical signal path reliability through gold-plated mating interfaces.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the M22 series, a family of industrial-grade connectors known for their robust construction and fine 2mm spacing. The series supports various configurations including single and double rows, catering to diverse board-to-board and cable-to-board applications across automotive and industrial sectors.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include M22-7130942 and M22-7131442 for single-row variations. For direct dual-row replacements, verify pin count and pitch compatibility with models like M22-6361042 or M22-6341042, ensuring identical mechanical dimensions and electrical ratings.
