MK 251 70 Z

Headers, Male Pins Overview

The MK 251 70 Z is a through-hole pin header from the Fischer Elektronik MK 251 series, designed for board-to-board and wire-to-board connections. It features a 2.54 mm pitch spacing and comprises 70 contacts arranged in two rows. The connector utilizes gold-plated CuZn-alloy contacts with a Ni+≥0.2µm Au surface finish to ensure reliable electrical performance. Key technical specifications include a volume resistance of ≤10 mΩ, shock resistance up to 50 g, and vibration resistance up to 15 g.

Headers, Male Pins Feature Summary

• Precision-engineered rectangular PCB connection using solder and plug pins with a 0.5 mm diameter
• Gold-plated contact surfaces ensuring high reliability and corrosion resistance
• Robust mechanical design supporting shock loads up to 50 g and vibration up to 15 g

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• Rectangular PCB assembly systems

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'Z' corresponds to the required contact plating and termination style as defined in the official datasheet. Confirm the 70-position count and 2-row configuration match the target circuit layout requirements before procurement.

Headers, Male Pins Selection Notes

Select this component when a 2.54 mm pitch through-hole header with 70 positions is required. Ensure the application environment does not exceed the specified 50 g shock or 15 g vibration limits. Verify compatibility with mating sockets regarding the gold-plated contact interface.

Headers, Male Pins Part Context

This part belongs to the MK 251 series, which offers precision-engineered solutions for reliable rectangular PCB connections. The series provides various contact counts and configurations within the same 2.54 mm pitch family, allowing for scalable design options across different board densities.

Headers, Male Pins Replacement Considerations

Compatible substitutes within the MK 251 series include variants with different contact counts such as MK 251 44 Z or MK 251 74 Z, provided the row count and pitch remain identical. Verify mechanical fit and electrical ratings before substitution.
