• I've got a Farnell EC30/2 bench supply here. It has a lurking cracked and knackered RIFA X class smoke bomb capacitor in it across the negative and ground terminals. This is GOING as I distrust the infernal things after a few small fires.
  
  This is a floating supply with no isolation or floating voltage limits specified.
  
  Now AFAIK this should be a Y rated capacitor in 2017. Am I ok stuffing a Y1 across it instead?

• In general, class X are for line to neutral applications, and class Y are for line or neutral to ground applications. So yes, if anything it should be class Y, and since Y1 is "better" than Y2, you should be OK.
