MK 251 74 G

Headers, Male Pins Overview

The Fischer Elektronik MK 251 74 G is a precision-engineered male pin header connector designed for reliable rectangular PCB connections. It features a 0.5 mm diameter solder and plug pin with a 2.54 mm (0.100 inch) pitch spacing. The component offers 74 positions arranged in two rows, utilizing through-hole termination for secure board mounting. Contact surfaces are gold-plated to ensure durability and low contact resistance. Rated for 1.5 A current and 60 VDC voltage, it operates within a temperature range of -40°C to 163°C. The housing meets UL94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Precision 0.5 mm diameter pins engineered for high-reliability rectangular PCB interconnections
• Gold-plated contacts provide durable electrical performance and corrosion resistance
• Two-row configuration supports 74 positions with standard 2.54 mm spacing

Headers, Male Pins Applications

• Board-to-board interconnection systems
• Wire-to-board connection assemblies
• High-density electronic circuit modules requiring robust mechanical stability

Headers, Male Pins Procurement Notes

Verify the specific part number suffix against official Fischer Elektronik documentation to confirm exact contact plating thickness and material specifications. Ensure compatibility with mating connectors regarding row count and pin alignment. Cross-reference thermal ratings with system operating conditions to validate performance under load. Confirm RoHS compliance status if required by project regulations.

Headers, Male Pins Selection Notes

Select this model when a 74-position, two-row header is required for through-hole PCB assembly. Consider the 0.5 mm pin diameter for applications needing precise alignment and reduced insertion force. Evaluate the 1.5 A current rating against circuit requirements. Choose based on the need for gold-plated contacts in environments where oxidation resistance is critical for long-term signal integrity.

Headers, Male Pins Part Context

The MK 251 series represents Fischer Elektronik's line of precision male headers. These components are characterized by their small 0.5 mm pin diameter, which allows for high-density packaging on printed circuit boards. The series is designed for applications demanding reliable mechanical and electrical connections in compact electronic devices.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik MK 251 variants with matching position counts, such as MK 251 72 G or MK 251 74 Z, provided the termination style and orientation align with the design constraints.
