The part numbering system of Samsung MLCC capacitors on p-6 defines 2 packaging codes in the part number of the products:
“size code” and
“size control code”
The “size code” defines Industry standard EIA size in inches (Metric size in mm)
The “size control code” defines the deviation from “Normal” size
“Normal” size - letter “N” (#9) in the p/n, defines Industry standard size tolerance while other letters in this field define other (larger) possible deviations
These tolerances/deviations should be taken into consideration while ordering the part or using it as an alternative to another vendor
Let’s look at the example:
