M20-9772642

Headers, Male Pins Overview

The M20-9772642 is a male pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a single row with 12 positions and a 2.54mm (0.100 inch) pitch. The housing is constructed from black polyamide material, rated UL94 V-0 for flammability. Contacts are made of brass with gold plating to ensure reliable conductivity. The connector supports a maximum voltage of 250V and a current rating of 3A per contact. It operates within a temperature range of -40°C to +105°C. The termination method is soldering, suitable for board-to-board or cable applications.

• UL94 V-0 rated black polyamide insulation for thermal stability
• Through-hole solder termination for secure PCB attachment

Headers, Male Pins Applications

• Board-to-board interconnections in industrial control systems
• Cable-to-board connections in consumer electronics assemblies
• Signal routing in automotive electronic modules
• General-purpose connectivity in telecommunications equipment

Headers, Male Pins Procurement Notes

Verify that the specific part number M20-9772642 matches the required 12-position single-row specification. Confirm that the through-hole mounting style aligns with the target PCB design constraints. Ensure compatibility with mating socket connectors from the same M20 series family to maintain proper engagement height and electrical performance standards.

Headers, Male Pins Selection Notes

Select this component when a single-row, through-hole male header is required for low-to-medium current signal transmission. The 2.54mm pitch offers standard spacing for general-purpose PCB layouts. Consider the gold contact plating for environments requiring long-term reliability against oxidation. Verify that the 3A current rating meets the application's electrical load requirements without derating.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their robust mechanical design and versatile mounting options. The M20 series includes various configurations such as surface mount and through-hole headers in multiple row counts and pitches. This specific model represents the through-hole variant optimized for durable mechanical fixation on printed circuit boards.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 12-position, 2.54mm pitch single-row male headers from manufacturers like Samtec or Molex, provided they match the through-hole termination and 3A current rating. Ensure the mating socket dimensions correspond exactly to the 0.100-inch pitch to guarantee proper fit and electrical continuity.
