M20-9971846

Headers, Male Pins Overview

The M20-9971846 is a male pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a dual-row configuration with 36 total positions arranged in a 2x18 layout. The contact pitch is standardized at 2.54 mm (0.100 inches). The contacts are gold-plated to ensure reliable conductivity and corrosion resistance. This vertical pin strip is intended for board-to-board or cable connections.

Headers, Male Pins Feature Summary

• Dual-row vertical pin header design for high-density interconnects
• Gold-plated contacts for enhanced signal integrity and durability
• Through-hole solder termination for secure PCB attachment

Headers, Male Pins Applications

• Board-to-board interconnection systems
• Cable-to-board wiring assemblies
• Industrial control panel interfaces
• General electronic equipment backplanes

Headers, Male Pins Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Harwin documentation. Confirm that the specific ordering suffix matches the required contact plating and row configuration. Ensure compatibility with standard 2.54 mm mating connectors. Check current lifecycle status as availability may vary due to production updates.

Headers, Male Pins Selection Notes

Select this component when a robust, high-current capable header is required for vertical mounting. The gold plating offers superior performance over tin variants in corrosive environments. Consider the 36-position count for space-constrained designs needing multiple signal lines. Verify that the through-hole footprint aligns with the target PCB manufacturing capabilities.

Headers, Male Pins Part Context

This part belongs to the M20 series, a widely used line of rectangular connectors known for reliability. The M20-9971846 specifically represents a high-pin-count variant within the vertical pin header category. It complements other M20 series sockets and housings to form complete connection solutions for complex electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical 36-position, 2.54 mm pitch, and gold-plated specifications. Verify mechanical dimensions and contact material before swapping with generic equivalents to ensure proper mating and electrical performance.
