MK 251 18 Z

Headers, Male Pins Overview

The MK 251 18 Z is a male pin header connector from the Fischer Elektronik MK 251 series, designed for through-hole PCB mounting. It features an 18-position configuration with a standard 2.54 mm (0.100 inch) pitch spacing. The contacts are constructed from brass alloy and are tin-plated to ensure reliable electrical connections. This component serves as a board-to-board or wire-to-board interface, providing a secure mechanical and electrical link in electronic assemblies.

Headers, Male Pins Feature Summary

• Precision-engineered solder and plug pins for rectangular PCB connections
• Through-hole mounting design for stable board integration
• Tin-plated brass contacts for corrosion resistance

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board interfaces
• General electronic assembly prototyping

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required contact count and pitch. Confirm that the tin-plated finish meets the environmental requirements of the application. Ensure the through-hole footprint aligns with the target PCB layout specifications before ordering.

Headers, Male Pins Selection Notes

Select this component when a 2.54 mm pitch male header is required for through-hole applications. Consider the 18-contact length relative to available board space. Evaluate the tin-plated surface against potential mating connector materials to ensure compatibility and long-term reliability.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik MK 251 series, which offers various contact counts including 24, 64, 74, 84, and 100 positions. The series provides consistent 2.54 mm spacing across different lengths, allowing for scalable connector solutions within the same product family while maintaining uniform mechanical dimensions.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik MK 251 variants with different contact counts, such as MK 251 24 Z or MK 251 64 Z, provided the circuit design accommodates the change in position count. Generic 2.54 mm pitch headers may serve as alternatives if exact brand matching is not required.
