M20-7820246

Overview

The M20-7820246 is a 2-position single in-line vertical socket assembly from the Harwin M20 series. It features a 2.54 mm pitch and is designed for board-to-board connections. The connector utilizes phosphor bronze contacts with gold and tin plating, housed in black UL94V-0 polyamide (nylon) 6T material. It supports a voltage rating of 1000 V and employs solder tail termination for through-hole mounting.

Feature Summary

• Vertical single in-line configuration for compact PCB integration
• Dual-plated contact finish combining gold and tin for reliability
• High-temperature resistant polyamide housing suitable for industrial environments

Applications

• General purpose electronic interconnections
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific contact plating configuration against project requirements, as datasheets indicate both gold and tin finishes. Confirm that the vertical orientation and 2.54 mm pitch align with the target PCB footprint. Ensure the component meets RoHS compliance standards required for the final assembly.

Selection Notes

Select this component when a low-profile vertical connection is needed for two signal lines. The nylon 6T housing offers thermal stability superior to standard materials. Consider the dual plating scheme if corrosion resistance and conductivity are critical for the application environment.

Part Context

This part belongs to the M20 series, which provides industrial-standard headers and sockets. The series is characterized by its compact design and high density capabilities. It is widely used in applications requiring reliable board-to-board connectivity with strict space constraints.

Replacement Considerations

Check for direct substitutes within the M20 family that match the 2-pin count and vertical orientation. Verify that any alternative maintains the same 2.54 mm pitch and UL94V-0 housing material to ensure mechanical and thermal compatibility.
