K2: C222 Capacitor Substitution OK?

[jperelst]

I can't find the last of the 100pf capacitors for C222 (NPO, 101)

 

I happen to have a spare 100pf that I used for another project, but it's the bigger, kind of orange colored, and roundish type instead of the little blue pillow-shaped type.  Is it ok to substitute the bigger one for the blue pillow-shaped type?

 

I don't have any leftover capacitors (other than those that should be left over), so I'm guessing that I lost the C222 capacitor somewhere on my work table.

Jon,

You can use the larger capacitor under 3 conditions.  1) The capacitance
is the same, 2) The voltage rating is as high or higher (I believe the
small blue ones are rated at 50 volts), and 3) You can make it fit
physically without resorting the long leads - C222 is used at 21 MHz.
