M20-9953946

Headers, Male Pins Overview

The M20-9953946 is a dual in-line horizontal pin header from the Harwin M20 series, designed for through-hole mounting. It features a 2.54 mm (0.1 in) pitch with 46 positions arranged in two rows. The connector utilizes a black nylon housing and tin-plated brass contacts rated for 3 A current and 750 V voltage. Operating within a temperature range of -40°C to +105°C, this component provides reliable board-to-board or wire-to-board interconnections.

• Tin-plated brass contacts ensure corrosion resistance and stable conductivity
• Nylon housing provides mechanical stability and electrical insulation

Headers, Male Pins Applications

• Board-to-board interconnection systems
• Wire-to-board assembly applications
• Industrial control unit interfaces
• Consumer electronics internal connections

Headers, Male Pins Procurement Notes

Verify the specific part number against official manufacturer documentation before procurement. Confirm that the horizontal orientation and 46-position count match the design requirements. Check RoHS compliance status and lead times directly with authorized distributors. Ensure soldering parameters align with the tin-plated contact specifications to maintain joint integrity during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a low-profile horizontal connection is required for high-density layouts. The 2.54 mm pitch ensures compatibility with standard PCB footprints. Consider the 3 A current rating for power distribution needs. Verify that the through-hole mounting style suits the manufacturing capabilities and mechanical stress requirements of the target application environment.

Headers, Male Pins Part Context

This part belongs to the M20 series, a widely used family of connectors known for reliability in harsh environments. The M20 series offers various configurations including single and double rows with different orientations. This specific model represents a high-pin-count solution within the horizontal variant category, suitable for applications requiring robust signal or power transmission across multiple channels.

Headers, Male Pins Replacement Considerations

M20-9953946 is an obsolete product scheduled for discontinuation. Engineers should evaluate alternative parts within the same M20 series or newer generations that offer equivalent pin counts and pitch specifications. Cross-reference mechanical dimensions and electrical ratings to ensure functional compatibility during the transition process.
