M22-2531205

Headers, Male Pins Overview

The M22-2531205 is a vertical pin header connector from the Harwin M22 series, designed for board-to-board or cable applications. It features a 12-position configuration with a 2.00mm (0.079 inch) mating pitch and dual-row arrangement. The connector utilizes through-hole termination for secure PCB mounting. Contacts are constructed from phosphor bronze with gold plating to ensure reliable signal transmission. The housing is made of black polyamide (PA6T), rated UL94 V-0 for flammability. It operates within a temperature range of -40°C to 105°C and supports a current rating of 1A per contact.

• Gold-plated phosphor bronze contacts provide durable conductivity and corrosion resistance.
• UL94 V-0 rated PA6T insulation ensures thermal stability and fire safety.
• Through-hole termination offers robust mechanical fixation on printed circuit boards.

Headers, Male Pins Applications

• Industrial control systems requiring reliable interconnects
• Consumer electronics with dense board layouts
• Automotive electronic modules
• Telecommunications equipment

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm contact plating and packaging details. Ensure compatibility with mating sockets regarding row spacing and pin count. Confirm RoHS compliance status if required by project specifications. Check for any recent obsolescence notices from the manufacturer before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when a vertical, dual-row header with 2.00mm pitch is required. Consider the 1A current rating and 105°C maximum operating temperature for environmental suitability. Verify that the through-hole mounting style aligns with the PCB assembly process. Compare against single-row alternatives if space constraints allow for reduced height.

Headers, Male Pins Part Context

This part belongs to the M22 series, a family of connectors known for their high-density capabilities and reliability in harsh environments. The series includes various configurations for headers, housings, and sockets, all sharing the standardized 2.00mm pitch. This specific model represents a standard vertical header variant within that ecosystem.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Harwin M22 series headers with identical 12-position, dual-row, vertical specifications. Verify exact dimensional tolerances and mating interface compatibility before substitution. Cross-reference with equivalent products from other manufacturers only if pinout and mechanical dimensions match precisely.
