M20-9961646

Headers, Male Pins Overview

The Harwin M20-9961646 is a right-angle pin header connector from the M20 series, designed for through-hole mounting. It features a single row with 16 positions and a 2.54 mm (0.100 inch) mating pitch. The connector utilizes square male pins made of brass with gold plating on the mating section. Insulation is provided by black polyamide (PA6T), rated UL94 V-0, supporting an operating temperature range of -40°C to 105°C. Each contact is rated for 3A current.

Headers, Male Pins Feature Summary

• Right-angle board-to-board or cable connection capability
• Gold-plated square male contacts for reliable signal transmission
• Cuttable design allowing for custom pin count configuration

Headers, Male Pins Applications

• General electronic equipment interconnections
• Industrial control systems
• Consumer electronics assemblies

Headers, Male Pins Procurement Notes

Verify the specific suffix '46' indicates tin plating on the termination pins, distinct from the gold mating contacts. Confirm the 16-position count matches the application requirements. Ensure the right-angle orientation fits the mechanical constraints of the PCB layout. Check for RoHS compliance documentation if required by project standards.

Headers, Male Pins Selection Notes

Select this component when a rigid, right-angle connection is needed in a limited vertical space. The cuttable feature allows flexibility in circuit design without needing unique part numbers for different channel counts. The PA6T insulation offers high thermal stability compared to standard nylon variants.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 family, known for robust rectangular connectors. The M20-996xx4x numbering convention typically denotes right-angle headers with specific termination and contact plating options. It serves as a standard interconnect solution within Harwin's broader portfolio of board-level hardware.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 2.54mm pitch right-angle headers from manufacturers like Samtec or Molex, provided they match the 16-position count, 3A rating, and through-hole termination style. Verify that the mating pin dimensions align with the specified 6.10mm engagement length.
