Your photo is small enough to be almost useless.
Google the package types (e.g. SOD-123) and see if it matches the package your device is in.
Look particularly at the way the contacts are formed on the package and its dimensions.
Also, I can't see that the device is damaged. Why do you think it's damaged? And if it is, do you think you'll be able to repair it?
If your phone was damaged by someone you had paid to perform a commercial service then I'm sure you have consumer laws in Germany that will enable you to get that company to fix the phone themselves. If you got a friend to do it, well, that's the risk you take.
