Heating one end and adding a little solder to the joint will allow you to
lift the cap,  the leads are folded over tabs so they'll bend nicely and
allow the cap to lift,  once you've got one end lifted,  heat the other and
it will come away easily.

Clean up the pads with solder wick then you're good to replace the part.

While I'd like an excuse (and the funds)  to buy a pair of tweezers for
SMD,  I'd find it hard to use that job as an excuse.
