If those were for decoupling (most likely), then use 100nF of type x7r or cog/npo or in worst case x5r. Even though the voltages are probably under 3.3v, use ceramics rated for 25v or higher ... 50v rated 100nF capacitors are easy to find in lots of sizes. x7r and x5r ceramics capacitance varies with voltage, an 100 nF with - let's say - 5v on it won't be 100nF, it would be much smaller.
The common ceramics used are 10nF , 100nF (0.1uF) , 470nF (0.47uF), 1uF etc
