MK 251 64 G

Headers, Male Pins Overview

The MK 251 64 G is a rectangular PCB connector header from the Fischer Elektronik MK 251 series. It features 64 positions arranged in a dual-row configuration with a 0.100 inch (2.54 mm) pitch. Designed for through-hole termination, the component utilizes gold-plated contacts to ensure reliable signal transmission. The connector supports a rated current of 1.5 A and a voltage of 60 VDC. Operating within a temperature range of -40°C to 163°C, it meets UL94 V-0 flammability standards for the insulation material.

Headers, Male Pins Feature Summary

• Dual-row pin header design for board-to-board or wire-to-board connections
• Gold-plated contacts on CuZn alloy pins for corrosion resistance
• Through-hole solder termination for secure PCB mounting
• High-precision rectangular contact geometry

Headers, Male Pins Applications

• Industrial control system interconnections
• Consumer electronics assembly
• General-purpose circuit board signal routing

Headers, Male Pins Procurement Notes

Verify the specific part number against official Fischer Elektronik documentation to confirm the 64-position count and dual-row layout. Ensure compatibility with mating connectors regarding pitch and row alignment. Check that the operating environment remains within the specified -40°C to 163°C range. Confirm that the required current does not exceed the 1.5 A rating per contact. Validate that the PCB hole dimensions match the 0.5 mm pin diameter specification.

Headers, Male Pins Selection Notes

Select this component when a 64-pin through-hole header is required for low-voltage applications. The 2.54 mm pitch ensures compatibility with standard PCB layouts. Consider the gold plating thickness if long-term corrosion resistance is critical. Verify that the dual-row format fits the available board space compared to single-row alternatives. Ensure the housing material meets the necessary flammability requirements for the end product.

Headers, Male Pins Part Context

This connector belongs to the MK 251 series, which offers various position counts including 2, 36, 52, 58, 62, 88, and 96 positions. The series provides consistent 2.54 mm spacing across different lengths. Fischer Elektronik manufactures these headers for general electronic industries, focusing on precision and durability. The 'G' suffix typically denotes gold plating in this product line.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik MK 251 series headers with equivalent pin counts, such as MK 251 62 G or MK 251 58 G, provided the position difference is acceptable. Cross-brand replacements must match the 2.54 mm pitch, dual-row structure, and through-hole termination method. Verify that alternative parts meet the same electrical ratings and temperature specifications.
