M20-7831146

Overview

The Harwin M20-7831146 is a PCB socket strip from the M20 series, designed for board-to-board applications. It features 22 positions (11+11) in a dual inline configuration with a 2.54 mm pitch. The connector utilizes through-hole solder pin termination and operates at temperatures ranging from -40°C to +105°C. Contacts are made of phosphor bronze with tin plating, housed in nylon insulation. Rated for 12A current, it meets RoHS standards and offers reliable vertical mounting for high-density circuit designs.

Feature Summary

• Dual inline configuration providing compact board-to-board connectivity
• Phosphor bronze contacts with tin plating for durable electrical performance
• Nylon housing compatible with standard surface mount thermal profiles
• Through-hole solder termination ensuring secure PCB attachment

Applications

• High-density PCB interconnects
• Board-to-board signal transmission
• Industrial electronic assemblies
• Consumer hardware modules

Procurement Notes

Verify the specific suffix '46' corresponds to the required tin-plated finish and contact configuration. Confirm that the 11+11 dual inline layout matches the target footprint requirements. Ensure compatibility with standard reflow or wave soldering processes specified for the M20 series. Cross-reference the official datasheet for precise mechanical dimensions to avoid assembly conflicts.

Selection Notes

Select this component when a 2.54 mm pitch dual row socket is required for vertical mounting. Consider the 12A current rating and -40°C to +105°C operating range for environmental suitability. Evaluate the through-hole installation method against available PCB space and manufacturing capabilities. Compare against single-row alternatives if position count allows for simplified routing.

Part Context

Part of the Harwin M20 series, which provides industrial standard sockets for demanding applications. The series supports various row counts and position options within a 2.54 mm grid. Designed for robust performance in electronics requiring reliable board-to-board connections. Compatible with standard manufacturing processes and widely used in diverse electronic equipment.

Replacement Considerations

Direct substitutes include other Harwin M20 series variants with matching 2.54 mm pitch and dual inline configurations. Verify identical pin counts and terminal types before substitution. Generic equivalents may exist but require strict verification of mechanical and electrical parameters.
