M20-9981845

Headers, Male Pins Overview

The M20-9981845 is a vertical pin header from the Harwin M20 series, designed for through-hole mounting. It features a dual in-line configuration with 36 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes gold-plated contacts for reliable signal transmission and includes tin-plated tails for soldering to printed circuit boards. Constructed with a black nylon insulation body, it supports board-to-board or cable connections. The component operates within a temperature range of -40°C to +105°C and carries an UL94 V-0 flammability rating for safety compliance.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact plating specifications and packaging details. Ensure compatibility with mating socket connectors regarding pin length and alignment tolerances. Confirm that the selected variant meets all required environmental and regulatory standards for the intended application environment before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count vertical header is required for dense circuit layouts. The dual-row arrangement maximizes connection capacity within a limited footprint. Consider the through-hole installation method for applications requiring robust mechanical stability. Evaluate the operating temperature range and current ratings to ensure suitability for the specific electrical load conditions of the target system design.

Headers, Male Pins Part Context

This part belongs to the M20 series, which offers a comprehensive range of rectangular connectors. The series provides various configurations including single and dual rows with different pin counts. The M20-9981845 specifically addresses needs for higher density connections compared to lower pin count variants within the same product family.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M20 series headers with matching 2.54 mm pitch and 36-position dual-row configurations. Verify that alternative parts maintain identical pin dimensions, insulation height, and termination style to ensure mechanical and electrical interchangeability without redesigning the host assembly.
