M20-7831646

Overview

The Harwin M20-7831646 is a 32-position, dual-row PCB header from the M20 series. It features a 2.54 mm pitch and vertical through-hole termination for board-to-board connections. The contacts are gold-plated bronze, rated for 12 A current at 105°C. The housing utilizes high-temperature liquid crystal polymer (LCP) with UL94V-0 flammability rating.

Feature Summary

• Dual-beam contact design ensures reliable electrical connection and mechanical stability.
• High-temperature LCP housing withstands surface mount reflow profiles.
• Gold plating provides superior corrosion resistance and conductivity.

Applications

• Board-to-board interconnects in industrial equipment
• High-density PCB assemblies requiring robust connectivity
• Automotive electronics modules

Procurement Notes

Verify the specific pin count and row configuration against the datasheet to ensure compatibility with the target PCB footprint. Confirm that the gold-plated variant meets the environmental requirements of the application, as standard tin-plated versions may differ in performance characteristics.

Selection Notes

Select this component when high reliability and thermal stability are required for vertical mounting. The gold plating is suitable for applications demanding low contact resistance and long-term durability in harsh environments compared to tin-plated alternatives.

Part Context

This part belongs to the Harwin M20 series, designed for compact, high-density PCB layouts. The series offers various configurations including single and double rows with different termination styles to support diverse electronic assembly needs.

Replacement Considerations

M20-7831646 is a specialized gold-plated variant. Direct substitutes may require matching the gold plating specification; otherwise, tin-plated equivalents like M20-7831646 (if available in tin) or similar M20 series headers should be evaluated for physical compatibility.
