WTB: FQA12P20 / FQA19N20 pairs

I have 2 F5 clones with IRFP's in them. I just wanted to try and compare them with FQA's.

I believe any matching is not needed because only one pair per channel is used.

I wasn't aware of FQA19N20C. what is the difference to FQA19N20 ? C-version could be used as complementary to P20 in F5? Then sure this is of interest.
