M20-7820742

Overview

The M20-7820742 is a rectangular socket connector from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 7 positions with a 2.54mm (0.100 inch) pitch and a single row configuration. The component utilizes gold-plated phosphor bronze contacts for reliable signal transmission and tin-plated brass termination pins for secure PCB mounting. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T) meeting UL94 V-0 flammability standards.

Feature Summary

• Push-pull locking mechanism ensures secure mating and prevents accidental disconnection during vibration.
• Gold-plated contact surfaces provide superior conductivity and corrosion resistance for long-term reliability.
• Polyamide insulation material offers high thermal stability and meets strict UL94 V-0 fire safety ratings.

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment infrastructure
• General-purpose electronic assemblies

Procurement Notes

Verify the obsolete status and end-of-life notification before finalizing design specifications. Confirm that alternative sourcing channels are available as standard distribution may be limited. Ensure compatibility with existing manufacturing processes regarding surface mount technology requirements and soldering profiles.

Selection Notes

Select this component when a low-profile, single-row socket with push-pull retention is required. Verify that the 7-position count matches the circuit design constraints. Consider the 2.54mm pitch compatibility with mating headers in the M20 series family. Evaluate the vertical orientation against available board space limitations.

Part Context

This part belongs to the M20 series, characterized by its compact form factor and high-density capabilities. The series is widely recognized for its versatility in connecting boards and cables across various industries. The specific model represents a socket assembly designed to mate with corresponding male headers, ensuring precise alignment and stable electrical connections.

Replacement Considerations

M20-7820742 is listed as obsolete. Potential substitutes include other Harwin M20 series sockets with identical pin counts and pitch, such as M20-7820746, provided they match the termination style and locking mechanism requirements.
