Difference of Apple Mac mini models Z12N and Z12P (both M1)

Does anybody know the difference between the Apple Mac mini M1 models Z12N and Z12P?

For example, here you can find two different products with the exact same configuration (512GB SSD / 16GB RAM):

• Z12N: https://www.conrad.de/de/p/apple-mac-mini-2020-mac-mini-mit-apple-m1-chip-512-gb-16-gb-apple-m1-macos-silber-2338419.html

• Z12P: https://www.conrad.de/de/p/apple-mac-mini-2020-mac-mini-mit-apple-m1-chip-512-gb-16-gb-apple-m1-macos-silber-2354165.html

Here you can also find an official reference as "Apple part number":

Is Z12P newer than Z12N? Different manufacturer?

Which would you choose?
