M20-7820446

Overview

The Harwin M20-7820446 is a 4-position, single-row PCB socket from the M20 series. It features a 2.54mm pitch and vertical through-hole termination. The connector utilizes phosphor bronze contacts with nickel over tin plating. Rated for 12A current, it operates within a temperature range of -55°C to 105°C. The housing is constructed from black nylon with UL94 V-0 flammability rating.

Feature Summary

• Vertical board-to-board interconnection design
• Through-hole solder termination for secure PCB mounting
• Nickel over tin plated phosphor bronze contacts
• UL94 V-0 rated black nylon insulation

Applications

• Board-to-board connections
• General electronic equipment interconnects
• Industrial control systems

Procurement Notes

Verify the specific contact plating configuration against official datasheets, as some listings may indicate gold options while standard specifications cite tin. Confirm that the 12A rating aligns with your thermal management requirements. Ensure the vertical orientation matches your assembly constraints.

Selection Notes

Select this component for applications requiring standard 2.54mm spacing with robust current handling capabilities. The vertical form factor suits dense panel mounting. Consider the tin plating for cost-effective solutions where high corrosion resistance is not critical compared to gold-plated alternatives.

Part Context

This part belongs to the Harwin M20 series, which provides industry-standard connectors for various electronic applications. The series offers multiple configurations including surface mount and right-angle options, ensuring compatibility with diverse PCB layouts and assembly processes.
