MK 251 20 G

Headers, Male Pins Overview

The MK 251 20 G is a rectangular connector header manufactured by Fischer Elektronik, designed for through-hole mounting. It features a 20-position configuration with a 0.100-inch (2.54 mm) pin spacing. The connector utilizes gold-plated contacts to ensure reliable signal transmission and includes a 0.098-inch (2.50 mm) insulation height. Rated for a maximum current of 1.5 A and a voltage of 60 VDC, it operates within a temperature range of -40°C to 163°C. The unit is supplied in bulk packaging and maintains UL 94 V-0 flammability ratings.

Headers, Male Pins Feature Summary

• High-precision male pin construction optimized for 0.5 mm diameter mating components
• Gold-plated contact surfaces provide durable corrosion resistance and stable electrical performance
• Through-hole termination method ensures secure mechanical attachment to printed circuit boards

Headers, Male Pins Applications

• Board-to-board interconnection systems requiring precise alignment
• Wire-to-board connections utilizing 0.5 mm diameter pins
• Electronic assemblies operating within standard industrial temperature ranges

Headers, Male Pins Procurement Notes

Verify the specific part number against official Fischer Elektronik documentation to confirm the 20-position count and gold plating specifications. Ensure that the through-hole footprint matches the target PCB design. Confirm that the rated current and voltage parameters align with the system requirements before procurement.

Headers, Male Pins Selection Notes

Select this component when a 20-position header with 2.54 mm spacing is required for 0.5 mm mating pins. Consider the 1.5 A current rating and 60 VDC limit for circuit compatibility. The through-hole format dictates PCB manufacturing constraints, while the gold finish supports applications demanding long-term reliability without soldering issues.

Headers, Male Pins Part Context

This component belongs to the MK 251 series of rectangular headers from Fischer Elektronik. The series provides standardized solutions for connecting board-level electronics using high-precision contacts. The MK 251 designation indicates a male pin header variant, distinct from female socket counterparts in the same product family.

Headers, Male Pins Replacement Considerations

Cross-reference compatible headers with identical 20-position counts, 2.54 mm pitch, and through-hole termination. Verify that substitute parts support 0.5 mm mating pins and offer equivalent gold plating thickness and current ratings.
