M20-7823046

Overview

The Harwin M20-7823046 is a 30-position double-row socket header from the M20 series, designed for board-to-board connections. It features a 2.54 mm pitch and through-hole vertical termination. The connector utilizes a UL94 V-0 rated high-temperature housing and copper alloy contacts with tin plating. It supports stacking heights of 11.04 mm and 12.63 mm, offering reliable electrical performance in compact PCB layouts.

Feature Summary

• Double-row configuration with jackscrew fixing options for secure mechanical retention
• High-temperature UL94 V-0 housing material suitable for demanding thermal environments
• Copper alloy contacts with tin plating to ensure stable signal transmission

Applications

• Board-to-board interconnects in industrial electronics
• Compact PCB stacking applications requiring precise alignment
• High-density electronic assemblies needing robust mechanical locking

Procurement Notes

Verify the specific variant required, as the M20-7823046 designation may correspond to single-row latching or double-row jackscrew versions depending on the manufacturer's current coding standards. Confirm stacking height requirements (11.04 mm or 12.63 mm) against your design specifications before ordering. Ensure compatibility with mating pin headers regarding contact geometry and insulation thickness.

Selection Notes

Select this component when a 30-position double-row socket is needed for vertical through-hole mounting. The 2.54 mm pitch is standard for general-purpose interconnects. Consider the jackscrew fixing mechanism if vibration resistance is critical. Verify that the tin-plated contacts meet the environmental corrosion requirements of the target application.

Part Context

This part belongs to the Harwin M20 series, which provides industrial-standard connectors for board-to-board applications. The series is known for its compact design and ability to meet strict PCB density and height constraints. These connectors are engineered to withstand reflow soldering processes similar to SMT components while maintaining durability.

Replacement Considerations

Direct substitutes within the same series include other M20 series sockets with matching position counts and pitch. Check for equivalent parts from Harwin with identical stacking heights and termination styles. Generic replacements must match the 2.54 mm pitch and double-row layout to ensure physical fit.
