M20-7850446

Overview

The M20-7850446 is a 8-position socket assembly from the Harwin M20 series, designed for surface mount technology. It features a 2.54 mm (0.1 in) pitch and utilizes a dual-row configuration with bottom entry orientation. The connector employs tin-plated contacts for reliable signal transmission and is housed in a nylon body. This component is specifically engineered for board-to-board and wire-to-board interconnections, offering a compact solution for high-density electronic applications requiring robust SMT integration.

Feature Summary

• Dual-row surface mount architecture optimized for space-constrained PCB layouts
• Bottom entry contact design facilitates efficient automated assembly processes
• Tin-plated brass contacts ensure stable electrical connectivity and corrosion resistance

Applications

• Industrial and factory equipment control systems
• Data collection hardware interfaces
• Mobile maintenance display units
• Portable test and measurement instrumentation

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions or limited distribution channels. Confirm that the specific tin-plated variant matches the required environmental specifications for the target application. Ensure compatibility with standard surface mount reflow profiles during the procurement planning phase to maintain connection integrity.

Selection Notes

Select this model when a low-profile, dual-row SMT header is required for 2.54 mm pitch applications. The bottom entry feature distinguishes it from top-entry variants, influencing PCB silkscreen and component placement strategies. Consider the tin plating finish for general-purpose environments rather than high-corrosion scenarios where gold plating might be preferred.

Part Context

This part belongs to the M20 series, a family of connectors known for their versatility in industrial and commercial electronics. The series offers various configurations including through-hole and surface mount options with different row counts and pin pitches. The M20-7850446 represents the specific 8-position, dual-row, SMT implementation within this broader product line.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific discontinued variant. Engineers should evaluate other M20 series components with identical 2.54 mm pitch and dual-row SMT characteristics, ensuring mechanical footprint and electrical ratings remain compatible with the existing design.
