M20-9970546

Headers, Male Pins Overview

The M20-9970546 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 2.54mm (0.100 inch) pitch with 10 positions arranged in a dual inline configuration. The connector utilizes square-shaped brass contacts with tin plating on both mating and tail sections. Insulation is provided by black polyamide (PA6T), rated UL94 V-0, supporting a working temperature range of -40°C to 105°C. It has a 3A current rating per contact and an unshrouded design suitable for board-to-board or cable applications.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current availability status. Check for any recent product change notices or end-of-life announcements that may affect supply continuity. Ensure compliance with RoHS and REACH regulations as specified in the manufacturer's environmental statements before procurement.

Headers, Male Pins Selection Notes

Select this component when a vertical, unshrouded header with a 2.54mm pitch is required. The dual inline format accommodates 10 contacts with a 3A rating. Consider the 8.51mm mating pin height requirement for compatible counterpart connectors. Verify that the through-hole soldering process aligns with the manufacturing capabilities.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a family of 2.54mm pitch PCB connectors known for their robust mechanical design. The M20 series offers various configurations including shrouded and unshrouded options. This specific model represents a standard vertical pin header variant within that extensive lineup.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 2.54mm pitch dual inline headers from manufacturers such as Samtec or Molex, provided they match the 10-position count, vertical orientation, and through-hole termination method. Verify dimensional compatibility for mating pins.
