M20-9981646

Headers, Male Pins Overview

The Harwin M20-9981646 is a vertical pin header from the M20 series, designed for through-hole mounting. It features a 2.54 mm pitch and consists of two rows with a total of 32 positions. The connector utilizes brass contacts with tin plating to ensure reliable signal transmission. Constructed with a nylon housing rated UL94 V-0, it supports a maximum current of 3A per contact. The operating temperature range spans from -40°C to +105°C, making it suitable for various board-to-board and wire-to-board applications requiring robust interconnection.

Headers, Male Pins Feature Summary

• Vertical pin header design with through-hole solder termination
• Dual-row configuration providing high-density connectivity
• Tin-plated brass contacts for corrosion resistance
• Nylon insulation housing with UL94 V-0 flammability rating

Headers, Male Pins Applications

• Board-to-board interconnections in industrial control systems
• Wire-to-board connections in consumer electronics assemblies
• General-purpose circuit board stacking applications
• High-density signal routing in telecommunications equipment

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability and lead times. Ensure that the tin-plated contact finish meets the environmental requirements of the target application. Check for RoHS compliance status if restricted substances are a concern. Confirm mechanical dimensions match the PCB footprint design before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a dual-row vertical header with a standard 2.54 mm pitch is required. The M20 series offers a wide range of position counts to accommodate different circuit densities. Consider the 3A current rating and 105°C temperature limit for thermal management planning. The through-hole installation method provides strong mechanical retention compared to surface-mount alternatives.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, which is a comprehensive family of connectors known for reliability and versatility. The M20 line includes various configurations such as single and double rows, shrouded and unshrouded options, and different contact finishes. This specific model represents a standard vertical header variant commonly used in general electronic manufacturing.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include other M20 headers with identical pitch and row count but different position numbers. Cross-referencing with generic 2.54 mm dual-row headers requires verification of housing height and contact length compatibility.
