Thank you for your reply.

How did you visually idenyify that left one is fake?

And what about left one? Can you tell me anything about it?

[Peter BENSCH]

The right one with the scrambled leads is marked with an extremely ugly font never used by STMicroelectronics.

You can also compare the logo with the one on our website.

The one on the left looks like genuine, but to be 100% sure you need the information on the label on the box / roll.
