MK 251 4 Z

Headers, Male Pins Overview

The Fischer Elektronik MK 251 4 Z is a male pin header designed for rectangular PCB connections. It features a 2-row configuration with 4 contacts and utilizes a 2.54 mm pitch. The component is intended for through-hole mounting in right-angle orientations. Contact materials consist of copper-zinc alloy, while the insulation is constructed from glass-filled polyamide (PA46).

Headers, Male Pins Feature Summary

• Rectangular PCB connection design
• Through-hole right-angle mounting
• Tin-plated contact finish

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic circuit assembly

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm the exact contact count and row configuration. Ensure that the required current rating and voltage specifications align with the application requirements. Confirm material certifications such as UL94 V-0 compliance if necessary for safety standards.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connector is required for dense PCB layouts. Consider the 2.54 mm pitch compatibility with existing board footprints. Evaluate the thermal and mechanical stability provided by the glass-filled PA46 insulation material for the operating environment.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik MK 251 series of precision-engineered solder and plug pins. The series is characterized by its 0.5 mm diameter pins optimized for reliable rectangular PCB connections. Variants within the series differ primarily in the number of contacts and rows available.

Headers, Male Pins Replacement Considerations

Check datasheets for alternative headers with identical 2.54 mm pitch and right-angle orientation. Verify that substitute components match the 2-row, 4-contact configuration and utilize compatible insulating materials.
