RIFA PME271M547 replacement
I would not be replacing a failed RIFA cap with an Ebay example of the same part of unknown age.

These old parts are notorious for failing in a cloud of foul smelling smoke, generally 30+ years after being made, basically the housing cracks, moisture gets in and it all goes sideways. 

The original is a 47nF 250V Class X2 cap.

Farnell have R463F247050N0K for less then your ebay part, that is coming from a proper distributor and will be of recent manufacture. 

Basically the important things for a cap in this role are that it be class X2, and rated for at least 250V, capacitance is not that critical.
