M20-7851546

Overview

The M20-7851546 is a dual in-line socket assembly from the Harwin M20 series, designed for board-to-board interconnections. It features 30 positions arranged in two rows with a 2.54 mm (0.1 inch) pitch. The connector utilizes through-hole termination and bottom entry design. Contact materials are specified as bronze with gold and tin plating to ensure reliable signal transmission. Constructed with nylon insulation, it supports standard PCB mounting configurations.

Feature Summary

• Dual row configuration providing high-density connectivity options
• Bottom entry design facilitates specific cable or wire harness routing
• Gold and tin contact plating ensures corrosion resistance and stable electrical performance

Applications

• Industrial control systems requiring robust board-to-board connections
• Communication equipment utilizing dual-row socket assemblies
• Test and measurement instrumentation interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Harwin documentation. Confirm that the specific ordering suffix matches the required contact plating and row configuration. Ensure procurement channels provide valid RoHS compliance statements. Check current lifecycle status as this item may be subject to discontinuation notices. Validate packaging specifications against project requirements before finalizing orders.

Selection Notes

Select this component when a dual-row, 30-position socket with bottom entry is required. The 2.54 mm pitch aligns with standard industrial spacing requirements. Consider the gold and tin plating for environments demanding enhanced contact reliability. Verify that the through-hole installation method suits the target PCB manufacturing capabilities. Evaluate the nylon insulation properties against thermal constraints of the application environment.

Part Context

This component belongs to the M20 series, a line of rectangular connectors known for their compact design and suitability for high-density applications. The series offers various configurations including headers and sockets with different row counts and entry styles. The M20-7851546 specifically addresses needs for dual-row socket assemblies with distinct entry geometries.

Replacement Considerations

Direct substitutes within the same series include M20-9981546, which shares similar dimensional characteristics but differs in pin type and orientation. Alternative options should maintain the 2.54 mm pitch and 30-position count. Verify compatibility regarding contact plating and entry direction when considering cross-series replacements.
