M20-7850342

Overview

The Harwin M20-7850342 is a double-row DIL socket assembly featuring 6 positions (3+3) with a 2.54 mm pitch. Designed for through-hole mounting, it utilizes a bottom-entry configuration with gold and tin contact finishes. The component supports a current rating of 3 A and a voltage rating of 1000 V. It incorporates a high-temperature UL 94V-0 housing constructed from polyamide insulation material.

Feature Summary

• Features a bottom-entry double-row design for secure board-to-board connections
• Utilizes gold and tin contact finishes to ensure reliable signal transmission
• Constructed with high-temperature UL 94V-0 polyamide housing for thermal stability

Applications

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

Procurement Notes

Verify the specific end-of-life status and obsolescence notifications directly with Harwin or authorized distributors before finalizing designs. Confirm that the through-hole bottom-entry configuration aligns with PCB layout requirements. Ensure compliance with RoHS directives and check for any regional distribution restrictions that may impact supply chain continuity for this discontinued series component.

Selection Notes

Select this component when a low-profile, double-row connector with bottom entry is required for through-hole applications. The 3+3 pin arrangement suits compact interfaces needing 6 contacts. Verify that the 1000 V rating and 3 A current capacity meet circuit demands. Consider the polyamide housing properties for environments requiring high thermal resistance and UL 94V-0 flammability ratings.
