M20-7860546P

Overview

The M20-7860546P is a vertical pin header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features a 2.54mm (0.100 inch) pitch and is configured as a single row with five positions. The connector utilizes through-hole termination for secure PCB mounting. Contact surfaces are finished with tin plating over nickel to ensure reliable electrical performance. The housing is constructed from black polyamide material rated UL94 V-0 for flame resistance. It operates within a temperature range of -40°C to +105°C and supports a current rating of 3A per contact.

Feature Summary

• Vertical orientation design facilitates standard board-to-board stacking configurations.
• Through-hole soldering provides robust mechanical fixation on printed circuit boards.
• Tin-plated contacts offer corrosion resistance and stable signal transmission.
• UL94 V-0 rated polyamide insulation ensures thermal stability and fire safety.

Applications

• Industrial control system interconnections
• Consumer electronics internal wiring
• Telecommunications equipment modules

Procurement Notes

Verify the specific suffix 'P' against the official Harwin datasheet to confirm if it denotes a particular packaging variant or tape-and-reel configuration distinct from the base model. Ensure compatibility with mating sockets regarding stack height and contact length specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, single-row vertical header is required for dense PCB layouts. The 2.54mm pitch is standard for general-purpose interconnects. Consider the 3A current rating and operating temperature limits to ensure suitability for the target application's electrical and environmental conditions.

Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their compact size and high reliability. The series offers various configurations including single and double rows, with options for surface mount or through-hole termination, catering to diverse electronic assembly needs.

Replacement Considerations

Direct substitutes may include other 5-position, 2.54mm pitch vertical headers from manufacturers such as Samtec or Molex, provided mechanical dimensions and electrical ratings match. Verify that alternative parts maintain the same through-hole footprint and UL94 V-0 insulation rating.
