M20-7880642

Overview

The M20-7880642 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 2-row configuration with 12 positions and a 2.54 mm (0.100 inch) pitch. The contacts are square-shaped male pins made of brass with tin plating on both mating and tail sections. The housing is constructed from black polyamide (PA6T/Nylon 6T), rated UL94 V-0 for flammability. It supports a current rating of 3A per contact and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Vertical through-hole design for board-to-board or cable connections
• Cuttable construction allows for custom position counts
• Push-pull locking mechanism secures mating connections
• Tin-plated brass contacts ensure reliable conductivity

Applications

• General electronic equipment interconnects
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability status and lead times. Ensure compatibility with mating sockets in the same M20 series family. Check for any recent lifecycle notices regarding obsolescence or last-time buys before finalizing procurement plans.

Selection Notes

Select this component when a vertical, cuttable header with push-pull retention is required. Confirm that the 2.54 mm pitch and 12-position count match the PCB layout. Verify that the through-hole termination method aligns with the assembly process and that the 3A current rating meets circuit requirements.

Part Context

This connector belongs to the Harwin M20 series, which offers a range of rectangular headers and wire housings. The M20 series is known for its modular design, allowing users to mix and match different row counts and termination styles while maintaining consistent mechanical and electrical performance across the product line.

Replacement Considerations

Compatible mating parts include M20-78xxxxx series sockets. For direct replacement, verify identical pitch, row count, and termination type. Cross-reference with other manufacturers' 2.54mm vertical headers only if mechanical dimensions and electrical ratings are fully compatible.
