M20-7820846

Overview

The M20-7820846 is a single-row female socket header from the Harwin M20 series, designed for board-to-board interconnections. It features 20 positions with a 2.54 mm pitch and utilizes through-hole solder termination. The connector employs a right-angle mounting style to facilitate compact PCB layouts. Constructed with a nylon housing and phosphor bronze contacts, it supports a rated current of 12A. The component operates within a temperature range of -40°C to 105°C and complies with RoHS standards.

Feature Summary

• Right-angle configuration enables space-efficient vertical stacking on printed circuit boards.
• Single-row receptacle design provides reliable board-to-board electrical connectivity.
• Through-hole solder termination ensures robust mechanical fixation during assembly.

Applications

• Board-to-board interconnects in industrial control systems
• Vertical stacking connections in compact electronic assemblies
• General-purpose signal routing in consumer electronics

Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in production. Sourcing requires verification of remaining stock or authorized distributors. Buyers must confirm availability prior to order placement due to discontinuation status. Alternative solutions should be evaluated if long-term supply stability is required for manufacturing.

Selection Notes

Engineers selecting this part must account for its discontinued status when planning product lifecycles. The right-angle form factor suits applications requiring vertical clearance management. Verify that the 2.54 mm pitch and 20-position count align with existing footprint constraints. Consider thermal and current ratings relative to the specific application load requirements.

Part Context

Part of the M20 series rectangular connectors, known for high-density board-to-board applications. The series offers various row counts and termination styles. This specific model represents a legacy single-row right-angle socket option within the broader Harwin connector portfolio.

Replacement Considerations
