No, the ceramic SMD capaciators is not an alternative of SMD Electrolytes for several reasons. First, capacitance. Ceramic SMDs is usualy in the ranges of pF-nF capacitance, where electrolytes are in the µF range. If there's a electrolytic capaciator in the design, replace it with a electrolytic one! And is there a ceramic one, replace it with a ceramic one! (But I must say I've never come across a broken ceramic cap .

And as people wrote before, you can fit a radial electrolytic cap most time to replace a surface mounted, but the pads on the PCB are designed for surface mounted caps.

Another hint is that all C= computers are using non-RoHS solder (Tin-Lead solder), so some precautions can be in place when using RoHS compliant solder (Tin-Silver-Copper). After desoldering, try to clean up as much of the (when desoldering) remaining mix of Tin-Lead / Tin-Silver-Copper from the pads with (recommended) Chemtronics "No Clean" 60BGA5 copper braid. This braid is designed for cleaning SMD pads after desoldering. And when refitting, use RoHS compliant solder.
