M20-9980545

Headers, Male Pins Overview

The Harwin M20-9980545 is a vertical, double-row pin header from the M20 series. It features a 2.54 mm pitch and contains 10 contacts arranged in a 2x5 configuration. The connector utilizes brass contacts with gold plating for reliable signal transmission. Designed for board-to-board or wire-to-board applications, it supports a rated current of 3A per contact. The housing is constructed from black nylon (PA6T) with UL94 V-0 flammability rating. Operating temperature ranges from -40°C to 105°C. The tail pins are designed for through-hole soldering with a length of 3mm, while the mating height is specified at 6.1mm.

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish upon order confirmation, as datasheet variations exist between gold and tin options for similar part numbers within the M20-998 series. Confirm that the required mating height aligns with system constraints, as this model specifies a 6.1mm engagement length. Ensure compatibility with existing PCB footprint designs before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a vertical, non-shrouded double-row header is required for high-density applications. The 2.54mm pitch ensures broad compatibility with standard connectors. Consider the gold plating variant for environments demanding superior corrosion resistance compared to tin-plated alternatives. Verify that the 3A current rating meets the specific circuit requirements for each individual contact path.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of rectangular connectors known for their versatility in mixed signal and power applications. The M20-998 suffix specifically denotes the vertical, double-row pin header configuration. This series offers various contact counts and plating options to suit diverse electronic assembly needs across multiple industries.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20-998 series headers with identical 10-position, double-row, vertical specifications. Cross-manufacturer replacements must match the 2.54mm pitch, 2x5 configuration, and through-hole mounting style to ensure mechanical and electrical compatibility.
