If I have a circuit that is designed for a ceramic, SMD, 0402, 1uF, 10%, 10V rated capacitor, and I swap in a ceramic, SMD, 0402, 1uF, 10%, 25V capacitor would anything change in the circuit?
Would the performance of the capacitor change in any significant or measurable way?
With high value ceramics like that, a higher specified voltage will mean a higher capacitance at your operating voltage. That is, the capacitor won't lose as much of its zero volts rated capacitance to voltage coefficient.
In decoupling applications, a little extra capacitance is a good thing. Given the tolerance of these capacitors, it's unlikely the circuit has been designed to rely on a particular reduced value.
