Why replace the working 4000 series devices, if they still work no need. Only change the dead ones, and if there are 2 or more with the same batch code that died then do all of those date code. Your replacement devices have much higher probability of either being dead from ESD damage or of being recycled and remarked fakes.
Only dipped tantalum capacitors on power rails had issues, and only there where they were used close to rated voltage. A 35V capacitor on a 5V rail almost never fails, but a 16V device on a 15V rail has a fair chance of popping, Replace with a regular 105C electrolytic, 20% tolerance is fine, and for a power rail you can go to the next higher capacitance and a higher voltage with very little issue, provided it will fit there. In any case a 100uF 63V 105C capacitor will replace any 10,22,47uF tantalum capacitor on a power rail with no problems, it will fit, and will have similar low ESR and a long life.
