M20-7850842

Overview

The Harwin M20-7850842 is a 16-position female socket connector from the M20 series, designed for through-hole mounting. It features a 2.54 mm (0.1 inch) pitch and utilizes gold-plated contacts to ensure reliable signal transmission. This receptacle supports both bottom and top entry configurations, providing flexibility in assembly orientation. The component is rated for a maximum current of 3A and operates within a temperature range of -40°C to +105°C. Constructed with durable materials, it serves as a robust interconnection solution for general electronic applications requiring secure board-to-board or cable connections.

Feature Summary

• Supports dual entry orientations for flexible PCB layout integration
• Gold-plated contacts provide corrosion resistance and stable conductivity
• Through-hole termination ensures mechanical stability during operation

Applications

• General-purpose electronic circuit interconnections

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Harwin documentation. Confirm that the specific suffix matches the required contact plating and entry style. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Check for obsolescence notices as availability may vary across distributors.

Selection Notes

Select this model when a 16-position female socket is required for through-hole PCB assembly. Consider the 2.54 mm pitch compatibility with mating headers. Evaluate the need for gold plating versus tin options based on environmental exposure. Verify that the operating temperature range meets the system's thermal requirements.

Part Context

This component belongs to the Harwin M20 series, which offers a comprehensive range of high-density connectors. The series is known for its reliability in demanding environments. The M20-7850842 specifically addresses the need for versatile entry points in a standard pitch format, fitting into broader industrial and consumer electronics design ecosystems.

Replacement Considerations

Direct substitutes within the same series include other positions such as M20-7850442 or M20-7851242. Ensure any replacement maintains the 2.54 mm pitch and through-hole mounting style. Verify that the contact material and plating specifications remain identical to preserve electrical performance.
