Pentosin CHF202 Alternatives or Substitutes?

I don't know the technical aspects about the different fluids, sorry. I've 'read somewhere' that Volvo recommends 202 for my P2 even though the initial fluid was 11S because some owners complained 11S caused a whine from the PS pump in extremely cold climate. But that's conjecture, as far as I know.
 
Thanks! From looking around it appears the CHF 202 and 11s fluids are cross compatible. This is so confusing, the other aftermarket compatible brands (Like the Febi 06161) will reference compatibility with either 202 or 11s specifically only. But I'm guessing these brands can all be interchanged with no noticeable difference.
