MK 251 90 Z

Headers, Male Pins Overview

The Fischer Elektronik MK 251 90 Z is a male pin header from the MK 251 series, designed for board-to-board and wire-to-board connections. It features a 2.54 mm pitch spacing and a 2-row configuration with 90 contacts. The component utilizes through-hole mounting for secure attachment to printed circuit boards. The contact material is specified as CuZn-alloy, ensuring reliable electrical performance in standard electronic assemblies.

Headers, Male Pins Feature Summary

• Rectangular PCB connection design
• Through-hole mounting technology
• Gold-plated contact surface

Headers, Male Pins Applications

• Board-to-board interconnects
• Wire-to-board connections
• General electronic assembly

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix 'Z' aligns with the required mechanical orientation or termination style as defined by Fischer Elektronik documentation. Confirm that the 90-position count matches the target PCB footprint requirements. Ensure compatibility with mating connectors within the same MK 251 series family to guarantee proper engagement and electrical continuity.

Headers, Male Pins Selection Notes

Select this component when a high-density 2-row header with 90 positions is required. The 2.54 mm pitch is standard for many legacy and industrial interfaces. Consider the operating temperature range of -40°C to 163°C for environmental suitability. Verify that the gold plating on the contacts meets the necessary corrosion resistance and conductivity standards for the application.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik MK 251 series, which offers various pin counts and configurations. The series is characterized by precision-engineered solder and plug pins with a 0.5 mm diameter. Other variants in the series include different contact counts such as 18, 44, 74, and 78 positions, all sharing the same 2.54 mm pitch and rectangular form factor.

Headers, Male Pins Replacement Considerations

Direct substitutes must be from the Fischer Elektronik MK 251 series with identical 2.54 mm pitch, 2 rows, and 90 positions. Generic headers may differ in contact material, plating thickness, or mechanical retention strength. Verify that any alternative maintains the same through-hole mounting profile and flammability rating.
