The absolute value doesn't really matter. Just as long as they are X2 caps which they are.

You're good to go.  :-+ 

Twoflower:
Isn't that thing on the left side of the picture a line-filter that's also notorious to fail?

There's no reason why you can't substitute X1 capacitors of course - they just have a higher voltage withstand rating.

PixieDust:
Thanks everyone for your help :-+.

Electro Detective:

Whoa   :o  hold up guys, there is a slight difference between X1 and X2 suppression capacitors 

X2 bridge across Live and Neutral

X1 are placed in line 

Also if an X2 has an associated resistor and cap with it (and or other parts) I am assuming the manufacturer has chosen the values to tune in a certain bandwidth to suppress
or whatever the result required for that particular power input circuit. 

i.e. till certain that 'any value will work' I reckon it's a better punt to wack in the original X2 value


FWIW: a worthy Youtube to watch   :clap:   if someone buys up on different value X2 caps and tests them in the same circuit to see what actual effect/difference they make.

In the meantime, I'll keep replacing old RIFAS with the same values the manufacturer installed...less thinking  :phew:
