M20-7893046

Overview

The Harwin M20-7893046 is a vertical pin header connector from the M20 series, designed for through-hole mounting. It features a single row with three positions and a 2.54mm pitch. The contacts are made of brass with tin plating to ensure reliable conductivity. Rated at 3A per contact, it supports board-to-board or cable connections within an operating temperature range of -40°C to 105°C. The housing utilizes black polyamide (PA6T) insulation rated UL94 V-0.

Feature Summary

• Vertical pin header configuration for standard PCB assembly
• Through-hole termination method for secure mechanical attachment
• Tin-plated brass contacts for corrosion resistance
• UL94 V-0 rated polyamide insulation for flame retardancy

Applications

• General electronic interconnects
• Industrial control systems
• Data center infrastructure
• Power applications

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current availability status and manufacturing revisions. Ensure that the tin-plated contact finish aligns with your soldering process requirements. Cross-reference the physical dimensions and pin count with your PCB footprint design prior to procurement to prevent assembly errors.

Selection Notes

Select this component when a low-profile, single-row header is required for signal or power routing. The 2.54mm pitch ensures compatibility with standard ribbon cables and mating sockets. Consider the 3A current rating and thermal limits to ensure the connector meets the electrical load requirements of the target circuit application without overheating.

Part Context

This component belongs to the Harwin M20 series, which provides 2.54mm pitch connectors conforming to industry conventions for pin header and socket systems. The series offers various configurations including single and double rows, surface mount and through-hole options, catering to diverse industrial and aerospace interconnect needs.

Replacement Considerations

Compatible mating sockets include models such as M20-7893046 variants or other M20 series female headers. Verify that any substitute maintains the same 2.54mm pitch and single-row layout to ensure proper mechanical fit and electrical continuity in the final assembly.
