This is the beginner section, so one should expect that a lot of the people starting threads here will not realize that counterfeits of even <$0.01 components can be found on fleabay, Ali-whatever, etc.

At least the OP learned this valuable lesson on a jellybean op-amp rather than, say, a $200 IGBT module...
