Hello everyone,
I have been looking for cheap yet nice amplifier boards on Aliexpress and other chinese websites and I have seen many obviously fake chips.
One example is the TPA3116 32 pins often replaced by a replaced by a CS8673E 16 pins, but easy to hide as the boards come with a heatsink.
Another example is the TPA3118 that has 32 pins but is often replaced by another chip that has only 28 pins.
The forum is full of people complaining about fake NE5532
So I am wondering are there components that we are safe to buy because they have not been counterfeited yet?

I wonder. In the years of CRT PC monitors, Toshiba 2SD5148 was a replace for most of the horizontal output transistors. There was a version in which the characters in the package was gray that runs only few minutes previous to shortcircuit. Those with white label stay operative during years. Differences were very sutile.
Some sellers resell someone else's product, the properties of which they do not understand. Others know that they are selling fakes, but they are cunning (they indicate well-known TI TPA3110, 3116, 3118 chips in the name). The specification may contain chips of own production CSxxxx or PAMxxxx.
Some sellers write that the image may differ. Don't like it don't buy 🙁
