M20-9991846

Headers, Male Pins Overview

The Harwin M20-9991846 is an 18-position, single-row pin header from the M20 series. It features a 2.54 mm pitch and is designed for vertical through-hole mounting. The connector utilizes brass contacts with tin plating to ensure reliable signal transmission. Rated for 3A current and operating within a temperature range of -40°C to +105°C, it supports board-to-board and wire-to-board applications. The housing is constructed from nylon without a cover.

Headers, Male Pins Feature Summary

• Vertical through-hole design for secure PCB integration
• Tin-plated brass contacts for corrosion resistance
• Single-row configuration for compact layout

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic equipment assembly

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish upon ordering, as the M20 series offers both gold and tin options across different suffixes. Confirm that the tin-plated variant aligns with your soldering process requirements and environmental specifications. Ensure compatibility with mating sockets regarding row count and pitch dimensions before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when an 18-contact solution is required in a single-row format. The tin plating provides a cost-effective alternative to gold for general-purpose applications where high conductivity over extended periods is not the primary constraint. Verify that the 2.54 mm pitch matches existing board layouts and mating hardware constraints.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of connectors known for their versatility in various industrial and consumer electronics. The series offers multiple configurations including single and double rows with varying contact counts. The M20-9991846 specifically addresses the need for mid-range density connections in space-constrained designs.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical 18-position, single-row, vertical, through-hole specifications. Ensure any replacement maintains the 2.54 mm pitch and compatible housing material. Cross-brand replacements must match the mechanical footprint and electrical ratings precisely.
