M20-7821346

Overview

The Harwin M20-7821346 is a single-row female socket header from the M20 series, designed for board-to-board connections. It features a 2.54 mm (0.1 inch) pitch and contains 13 positions. The connector utilizes through-hole termination with tin-plated contacts made of bronze. The housing is constructed from black nylon, offering UL94 V-0 flammability rating. It operates within a temperature range of -40°C to +105°C and supports a current rating of 12A.

Feature Summary

• Double-beam contact design for improved electrical connection and reliability
• Compact vertical profile suitable for high-density PCB applications
• Compatible with standard SMT reflow processes despite THT construction

Applications

• Embedded PC systems
• Motherboard interconnects
• Industrial monitoring equipment
• Consumer electronics assemblies

Procurement Notes

Verify the specific pin count and row configuration against the datasheet before ordering, as the M20 series includes various multi-row variants. Confirm that the through-hole termination method aligns with the target PCB assembly process. Ensure environmental compliance requirements match the RoHS certification status provided in the official documentation.

Selection Notes

Select this component when a single-row, vertical female interface is required for direct board stacking. The 2.54 mm pitch is standard for general-purpose industrial connectors. Consider the 12A current rating and thermal limits for power distribution needs. The straight orientation simplifies layout compared to right-angle alternatives.

Part Context

This part belongs to the Harwin M20 series, a widely adopted line of rectangular connectors known for their robust mechanical design and compact footprint. The series offers both single and double-row configurations in through-hole and surface-mount formats, serving as a standard solution for embedded computing and control systems.

Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical 13-position single-row specifications. Verify compatibility with mating male pins regarding contact plating and beam design to ensure reliable engagement.
