I'm no xpert fer sure but in my opinion any semiconductor purchased from
a manufacturer should be an ok part since all the manufacturers have
safeguards in place to insure that the parts they purchase meet the
required specs. Way back when Magnavox was Magnavox I worked there and I
know they had an entire department set up to inspect and test incoming
parts by testing a sample of every batch, if the sample failed the
entire batch was rejected and returned to the supplier. Guess where the
cheap generics come from!
