Capacitor substitution

I'm building an Aion Elysium board
It calls for a 5pf ceramic capacitor but I only have a 4.7pf
Given parts tolerance, do you guys think it will be Ok anyway? Both my TC7 and my multimeter aren't able to measure it so I don't know the actual value
This is the schematic, if I'm reading it correctly it's connecting pins 11 and 12 of IC 4

You can use a bigger cap in parallel to measure small value caps
Try a 20pf or so
Measure the big cap. Then both.
But yeah, your fine
Disc caps are usually+/-20%
Probably just to tame hf noise/oscillation
Edit:you want to use a big enough cap that your meter reads it but not so big that you lose the tenths readout

Great suggestion! Thanks
