Micron Capacitors Value

I bought a Micron second hand a few weeks ago and on the capacitors blew up.
I need to replace it but the value of the mounted one and the value on the Bill of Materials differ.

The mounted one reads 4700uf 16V while the BOM says it should be 2200uf 16V.

Since it is a second hand product I don't know which one I should follow.
Can someone help me ?
