M20-9971845

Headers, Male Pins Overview

The M20-9971845 is a vertical pin header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features a 36-position single-row configuration with a 2.54mm (0.100 inch) pitch. The connector utilizes square male pins made of brass with gold plating on the mating interface. It is constructed from black polyamide (PA6T) insulation rated UL94 V-0 and supports through-hole solder termination. The component operates within a temperature range of -40°C to +105°C and carries a current rating of 3A per contact.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm pin count, plating type, and packaging details against the official Harwin datasheet. Ensure compatibility with mating socket connectors regarding height and pitch specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a high-density, vertically oriented connection is required for PCB assemblies. The 36-position layout suits applications needing extensive signal or power routing in a single row. Consider the gold plating for environments requiring corrosion resistance and low contact impedance. Verify that the through-hole footprint matches the target PCB design constraints.

Headers, Male Pins Part Context

This part belongs to the M20 series of rectangular connectors manufactured by Harwin Inc. The series is characterized by its robust mechanical design and versatile positioning options. The M20-9971845 specifically represents a high-pin-count variant within the vertical header category, offering a standardized solution for modern electronic interconnect needs.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 36-position, 2.54mm pitch vertical headers from Harwin's M20 line, such as M20-9971846 if tin plating is acceptable. Cross-brand equivalents must match the 2.54mm pitch, 36-pin count, and vertical orientation while ensuring compatible housing dimensions and terminal styles.
