The capacitor you should be looking for will read on it 1000uf 16V.

The voltage is not so important, it could be 16V, 20V etc, It will definately NOT be under 16v.

replacement should read same capacitance value - 1000uf but voltage rating can be 16v or higher

Last noob question (for tonight) is 1000mdf the same as 1000uf?
