M20-9953945

Headers, Male Pins Overview

The M20-9953945 is a dual in-line horizontal pin header from the Harwin M20 series, designed for board-to-board or wire-to-board connections. It features 78 positions arranged in two rows with a 2.54 mm (0.1 inch) pitch. The connector utilizes through-hole solder termination and straight mounting orientation. Contacts are gold-plated brass pins, ensuring reliable conductivity. The housing is constructed from black nylon rated UL94 V-0 for flame resistance. 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

• Dual row configuration provides high-density connectivity in a compact footprint
• Gold-plated contacts ensure durable signal transmission and corrosion resistance
• UL94 V-0 rated nylon insulation offers thermal stability and flame retardancy
• Horizontal orientation facilitates space-constrained PCB layout designs

Headers, Male Pins Applications

• High-density electronic assemblies requiring robust interconnects
• Industrial control systems operating in varied thermal environments
• Consumer electronics utilizing standard 2.54 mm spacing interfaces
• Automotive circuit boards needing reliable signal routing

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and insulation material grade against the official Harwin datasheet before integration. Confirm that the horizontal mounting style aligns with your PCB mechanical constraints and assembly process capabilities. Ensure compatibility with mating connectors regarding stack height and engagement force specifications.

Headers, Male Pins Selection Notes

Choose this component when a dual-row, horizontal header is required for dense signal routing. The 2.54 mm pitch ensures compatibility with standard breadboards and ribbon cables. Gold plating is suitable for low-signal applications where oxidation resistance is critical. Verify that the 3A current rating meets the electrical load requirements of your specific circuit design.

Headers, Male Pins Part Context

This part belongs to the M20 series, a widely used line of rectangular connectors known for their reliability and versatility. The series offers various configurations including single and double rows with different orientations. The M20-9953945 specifically addresses needs for high-pin-count horizontal headers in professional electronic manufacturing.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series dual-row horizontal headers with matching 78-position counts and 2.54 mm pitch. Cross-brand replacements must match the physical dimensions, pin configuration, and electrical ratings precisely to ensure functional equivalence.
