M20-7881246

Overview

The Harwin M20-7881246 is a dual-in-line horizontal socket connector from the M20 series, designed for board-to-board applications. It features 24 positions with a 2.54 mm pitch and utilizes through-hole termination. The contacts are gold-plated on the mating interface with tin plating elsewhere, housed in a nylon body. Rated for 3 A current and 750 V voltage, it operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-in-line horizontal configuration for compact PCB integration
• Gold-plated contact surfaces ensure reliable signal transmission
• Nylon housing provides thermal stability up to 105°C

Applications

• Board-to-board interconnects
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific part number M20-7881246 against official Harwin documentation to confirm availability status and manufacturing lifecycle stage. Ensure compatibility with mating pin headers regarding pitch and row alignment. Check for RoHS compliance requirements relevant to your region before finalizing procurement orders.

Selection Notes

Select this component when a horizontal female connector is required for high-density layouts. The 2.54 mm pitch suits standard industrial interfaces. Consider the gold-tin plating combination for corrosion resistance and solderability. Verify that the 3 A rating meets the circuit's electrical demands.

Part Context

This connector belongs to the Harwin M20 series, which adheres to industry-standard 2.54 mm spacing conventions. The series offers various configurations including vertical and right-angle options. This specific model represents a horizontal socket variant suitable for surface-mounted or through-hole assembly processes depending on the specific design constraints.

Replacement Considerations

Direct substitutes must match the 24-position count, 2.54 mm pitch, and horizontal orientation. Verify that alternative manufacturers offer compatible gold-tin plating specifications. Ensure mechanical dimensions align with existing PCB footprints to avoid rework.
