M20-7823546

Overview

The Harwin M20-7823546 is a single-row socket header from the M20 series, featuring a 2.54 mm pitch and 23 positions. Designed for board-to-board applications, it utilizes through-hole termination with solder tails. The connector employs nickel-plated tin contacts made of phosphor bronze, housed in a nylon insulator. It supports a rated current of 12A and operates within a temperature range of -40°C to +105°C. This component is part of the industrial standard M20 line, engineered for high-density PCB layouts.

Feature Summary

• Single-row socket configuration with 2.54 mm spacing for compact board-to-board integration
• Through-hole solder tail termination ensuring robust mechanical fixation on printed circuit boards
• Phosphor bronze contacts with nickel plating and tin finish for reliable electrical conductivity

Applications

• Embedded PC systems requiring high-density interconnects
• Industrial monitoring and control equipment
• Communication devices utilizing standard board-to-board interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number M20-7823546 with official Harwin documentation. Confirm that the received items match the specified 23-position single-row socket configuration. Ensure compliance with RoHS standards as indicated in the product specifications. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when a 23-position through-hole socket is required for vertical mounting. The 2.54 mm pitch aligns with standard industry spacing for board-to-board connections. Consider the 12A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the nylon housing material meets the thermal and mechanical requirements of the specific application design.

Part Context

The M20 series represents a family of industrial standard PCB connectors designed for high reliability. These connectors are characterized by their compact form factor and durable construction, suitable for demanding electronic environments. The M20-7823546 specifically serves as a socket counterpart to male headers within this ecosystem, facilitating standardized interconnections across various hardware platforms.

Replacement Considerations

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Engineers should identify alternative parts from the same M20 series or compatible families that maintain the 2.54 mm pitch and 23-position configuration. Verify pinout compatibility and mechanical dimensions before substituting.
