M20-7823846

Overview

The Harwin M20-7823846 is a 38-position, dual-row board-to-board socket assembly from the M20 series. It features a 2.54 mm pitch and utilizes through-hole termination for secure mounting. The connector employs nickel-plated tin contacts housed in a black nylon shell, rated for 12A current at 105°C maximum operating temperature. Designed for high-density PCB applications, it ensures reliable signal transmission with robust mechanical stability.

Feature Summary

• Dual-row configuration optimized for space-constrained board-to-board interconnects
• Through-hole solder tail design provides enhanced mechanical retention on printed circuit boards
• Nickel-plated tin contact finish ensures corrosion resistance and reliable conductivity

Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Communication equipment internal bus connections

Procurement Notes

Verify the specific pin count and row configuration against the schematic requirements before ordering. Confirm that the through-hole footprint matches the target PCB layout dimensions. Ensure compatibility with standard reflow soldering profiles to maintain contact integrity during assembly processes.

Selection Notes

Select this component when a rigid, dual-row connection is required for board stacking or modular expansion. The 2.54 mm pitch aligns with industry-standard spacing, facilitating integration with existing header components. Consider the through-hole mounting style if vibration resistance is a critical design factor compared to surface-mount alternatives.

Part Context

This part belongs to the Harwin M20 series, a widely adopted line of industrial-grade connectors known for durability and precision. The series supports various configurations including single and double rows with different termination styles. The M20-7823846 specifically addresses needs for medium-density interconnects requiring robust physical locking mechanisms.

Replacement Considerations

Cross-reference with other M20 series sockets sharing identical pitch and row counts. Verify that alternative suppliers offer compatible housing materials and contact plating specifications to ensure functional equivalence without redesigning the PCB footprint.
