M20-9980946

Headers, Male Pins Overview

The M20-9980946 is a vertical pin header connector from the Harwin M20 series, designed for board-to-board and wire-to-board applications. It features a 2.54 mm (0.100 inch) pitch with 18 contacts arranged in a dual-row configuration. The connector utilizes through-hole termination for secure PCB mounting. Contacts are made of brass with tin plating to ensure reliable conductivity. The insulating housing is constructed from black polyamide (PA6T), rated UL94 V-0 for flammability. It operates within a temperature range of -40°C to +105°C and supports a current rating of 3A per contact.

Headers, Male Pins Feature Summary

• Tin-plated brass contacts for corrosion resistance and conductivity
• UL94 V-0 rated black PA6T insulation for thermal stability
• Through-hole solder termination for robust mechanical fixation

Headers, Male Pins Applications

• Board-to-board connections in industrial control systems
• Wire-to-board interfaces in consumer electronics
• Signal routing in telecommunications equipment
• General-purpose interconnects in automotive modules

Headers, Male Pins Procurement Notes

Verify the specific part number M20-9980946 against official Harwin documentation to confirm the 18-position dual-row specification. Ensure compatibility with mating sockets or cables regarding pitch and row alignment. Check for RoHS compliance status if required by project regulations. Confirm that the through-hole footprint matches the target PCB design guidelines before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a 2.54 mm pitch vertical header with 18 positions is required. The dual-row layout suits applications needing increased I/O density in limited space. The tin-plated finish offers standard environmental protection suitable for general use. Consider the 3A current rating and 105°C operating limit to ensure electrical safety under expected load conditions.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of rectangular connectors known for their reliability and versatility. The M20 series includes various configurations such as single and double rows, different contact counts, and optional shrouds. The M20-9980946 specifically represents the unshrouded dual-row variant, providing flexibility for custom cable assemblies or direct board stacking without height restrictions imposed by covers.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M20 series headers with identical 2.54 mm pitch, 18 positions, and dual-row layout, such as M20-9980846 or M20-9981046, provided they match the pin count and orientation. Cross-brand replacements must strictly adhere to the 2.54 mm spacing and mechanical dimensions to ensure fit.
