MK 226 SMD 28 G SM

Headers, Male Pins Overview

The MK 226 SMD 28 G SM is a surface-mount male pin header manufactured by Fischer Elektronik. It features 28 positions with a 0.100-inch (2.54 mm) pitch spacing. The connector utilizes turned precision contacts made from CuZn alloy with gold plating on the contact surfaces, specifically Ni+≥0.2µm Au. The insulation material is polyamide (PA46), glass-filled nylon 4/6, rated UL94 V-0 for flammability. The operating temperature range spans from -40°C to 163°C.

Headers, Male Pins Feature Summary

• Surface-mount design with turned precision contacts for reliable board attachment
• Gold-plated contact surfaces ensuring corrosion resistance and stable conductivity
• High-temperature resistant polyamide insulation material with UL94 V-0 rating

Headers, Male Pins Applications

• Surface-mount PCB interconnections requiring high reliability
• Industrial electronics assemblies operating in elevated temperatures
• Precision instrumentation connectors

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'G' corresponds to the gold-plated contact configuration as documented in official Fischer Elektronik datasheets. Confirm that the 28-position count matches the required circuit density. Ensure the surface-mount footprint aligns with the PCB layout specifications provided in the component drawing. Cross-reference the insulation material properties against thermal requirements of the target application environment.

Headers, Male Pins Selection Notes

Select this component when surface-mount technology is mandatory for the assembly process. Choose this variant over through-hole options to save vertical space on the PCB. Consider the gold plating requirement if the application demands superior contact stability or resistance to oxidation compared to tin-plated alternatives. Verify that the 2.54 mm pitch fits the existing connector mating hardware constraints.

Headers, Male Pins Part Context

This part belongs to the MK 226 SMD series of male headers from Fischer Elektronik. The series offers various contact counts ranging from 6 to 44 positions. Variants within the series differ primarily by contact plating (gold vs. tin) and position count. The 'SM' suffix indicates surface-mount compatibility, distinguishing it from other mounting styles in the product line.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik MK 226 SMD variants with identical 28-position counts and gold-plated contacts, such as MK 226 SMD 28 Z SM if tin plating is acceptable. Ensure any replacement maintains the 2.54 mm pitch and surface-mount footprint to guarantee mechanical fit.
