M20-7892442

Overview

The M20-7892442 is a surface-mount socket header manufactured by Harwin Inc. within the M20 series. It features a 24-position, single-row configuration with a 2.54 mm pitch. The connector utilizes gold-plated phosphor bronze contacts and a black polyamide (PA6T) insulator rated UL94 V-0. Designed for board-to-board or wire-to-board applications, it supports a maximum current of 3A per contact at 250V. The component operates within a temperature range of -40°C to 105°C and employs a push-pull locking mechanism.

Feature Summary

• Push-pull locking mechanism ensures secure mating retention
• Gold-plated phosphor bronze contacts provide reliable conductivity
• UL94 V-0 rated black PA6T insulation offers flame resistance

Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic equipment assembly

Procurement Notes

Verify the specific suffix '442' against official datasheets to confirm the exact tail length and housing variant. Ensure compatibility with mating headers regarding stacking height and locking style. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component for high-density SMT layouts requiring robust mechanical retention. The 2.54 mm pitch suits standard PCB footprints. Evaluate thermal requirements against the 105°C limit. Consider the push-pull feature for applications needing frequent disconnection without soldering damage.
