For Advance drivers, the trailing digit in the part number indicates the generation of the driver. Generally, a higher generation is a suitable replacement for a previous generation. When replacing a product belonging to the same generation (with the same exact part number) you can use MultiOne Mobile for Android phones and use the cloning function to "copy - paste" the settings from the source driver to the target driver. However, note that a newer generation cannot be cloned from a previous generation. You will need to read the settings from the source driver and then program the replacement driver using the MultiOne Engineering PC based software.
