M20-9970645

Headers, Male Pins Overview

The Harwin M20-9970645 is a vertical pin header connector from the M20 series, designed for board-to-board and cable-to-board interconnections. It features a 2.54mm pitch spacing with 12 contacts arranged in two rows. The connector utilizes brass contacts with gold plating for reliable signal transmission. It supports through-hole mounting and solder termination. The housing is constructed from black nylon material, rated UL94 V-0 for flammability. Operating temperature range spans from -40°C to 105°C, with a current rating of 3A per contact.

Headers, Male Pins Procurement Notes

Verify the specific part number M20-9970645 against official Harwin documentation to confirm the two-row, twelve-position configuration. Ensure compatibility with mating connectors regarding pitch and row alignment. Check for RoHS compliance status if required by project specifications. Confirm that the vertical mounting style matches the mechanical constraints of the target printed circuit board assembly.

Headers, Male Pins Selection Notes

Select this component when a dual-row header is required for dense signal routing within a 2.54mm grid system. The vertical form factor suits applications where height clearance is available but lateral space is limited. Consider the 3A current rating and operating temperature range to ensure suitability for the intended electrical load and environmental conditions. Verify that the cuttable feature aligns with the manufacturing process for customizing contact counts.

Headers, Male Pins Part Context

This connector belongs to the Harwin M20 series, which offers a range of pin headers with 2.54mm pitch. The series includes various configurations such as single and double rows, different contact counts, and both straight and right-angle orientations. The M20-9970645 specifically represents a double-row variant, distinguishing it from single-row counterparts like the M20-9990645 or M20-9991645 found in related product listings.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54mm pitch, 12-position count, and double-row layout. Generic equivalents may vary in housing material or contact plating thickness. Verify mechanical dimensions and locking mechanisms before substitution. No specific alternative part numbers are confirmed in the provided source data.
