M22-2520246

Headers, Male Pins Overview

The M22-2520246 is a vertical pin header assembly from the Harwin M22 series, designed for board-to-board interconnections. It features a 2mm pitch and a 2+2 position configuration (four pins total) arranged in a dual inline layout. The connector utilizes phosphor bronze contacts with tin plating to ensure reliable electrical performance. Rated for 1A current and 650VAC voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from nylon material, providing mechanical stability and UL 94 V-0 flammability rating. This through-hole solder termination component is engineered for high-density PCB applications requiring robust connectivity.

Headers, Male Pins Feature Summary

• Vertical dual inline pin header design optimized for space-constrained board-to-board connections
• Tin-plated phosphor bronze contacts provide durable electrical interfaces with corrosion resistance
• Nylon housing offers structural integrity and meets UL 94 V-0 flammability standards

Headers, Male Pins Applications

• Embedded PC systems
• Motherboard interconnects
• Large electronic system backplanes

Headers, Male Pins Procurement Notes

Verify the specific contact count and orientation against project requirements before ordering. Confirm that the tin plating specification aligns with the intended environmental conditions and soldering processes. Ensure compatibility with mating socket components within the M22 series ecosystem. Check for any recent product change notifications or obsolescence alerts from the manufacturer to guarantee long-term supply availability.

Headers, Male Pins Selection Notes

Select this component when a low-profile, vertical header with a 2mm pitch is required for compact designs. The tin-plated finish is suitable for general-purpose applications where gold plating is not strictly necessary. Consider the 1A current rating and 650VAC voltage limit to ensure they meet the circuit's operational demands. Verify that the through-hole mounting style fits the PCB fabrication capabilities and mechanical constraints of the assembly.

Headers, Male Pins Part Context

This part belongs to the M22 series, a family of industrial standard connectors known for their fine 2mm spacing and high reliability. The series supports various configurations including single and double rows with multiple pin counts. These connectors are widely adopted in embedded computing and communication equipment due to their compact form factor and ability to withstand reflow soldering processes similar to SMT versions.

Headers, Male Pins Replacement Considerations

M22-2520246 is listed as an obsolete product. Potential substitutes include other Harwin M22 series headers with matching 2mm pitch, vertical orientation, and tin-plated contacts. Verify pin count and housing material compatibility when selecting alternative parts.
