M20-9993446

Headers, Male Pins Overview

The M20-9993446 is a single-row vertical pin header from the Harwin M20 series, featuring 34 positions with a 2.54 mm pitch. It utilizes tin-plated brass contacts and a black nylon insulator for board-to-board or wire-to-board connections. Designed for through-hole soldering, this component supports a rated current of 3A per contact and operates within a temperature range of -40°C to +105°C. The connector system is unshrouded with square male pins, ensuring reliable mechanical retention and electrical performance in standard electronic assemblies.

Headers, Male Pins Feature Summary

• Single-row vertical configuration with 34 positions
• Tin-plated brass contacts for corrosion resistance
• Nylon insulation housing with UL94 V-0 flammability rating
• Through-hole solder termination for secure PCB mounting

Headers, Male Pins Applications

• General-purpose board-to-board interconnects
• Wire-to-board signal distribution
• Industrial control panel wiring
• Consumer electronics internal connections

Headers, Male Pins Procurement Notes

Verify part authenticity by cross-referencing the manufacturer's official datasheet and ordering suffixes. Confirm that the specific tin-plated variant matches design requirements. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions maintain contact integrity prior to assembly. Validate lead length specifications against PCB hole dimensions.

Headers, Male Pins Selection Notes

Select this component when a high-density single-row header is required for vertical mounting. The 2.54 mm pitch ensures compatibility with standard PCB layouts. Tin plating offers cost-effective conductivity for non-high-frequency applications. Consider the 3A current rating for power distribution needs. Verify that the unshrouded design fits within the enclosure constraints.

Headers, Male Pins Part Context

This part belongs to the M20 series, a widely used line of rectangular connectors known for their robust mechanical design and versatile positioning options. The M20 family includes various row counts and configurations, catering to diverse connectivity demands in industrial and commercial electronics. This specific model represents a high-pin-count option within the single-row vertical category.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 34-position 2.54mm pitch headers from manufacturers like Samtec or Molex, provided they match the vertical orientation and through-hole termination. Ensure equivalent current ratings and temperature ranges are maintained. Verify that the contact material and plating offer similar corrosion resistance profiles.
