hi,
You could increase the values of the two resistors, say by times 5, until the 0.047uF is available.
Use the formula inthe datasheet to work out the exact frequency

from the formula in the datasheet(astable operation): using the values as they are with 0.05uF i get f = 3.3111...khz
for 1.2K x 5 = 6K and 3.9K x 5 = 19.5K i also get something similer which is 3.3111...khz
would i find 19.5K or i have to make serial connection of 3.9K's?

i was mistaken about the 0.01uF cap. they don't have one. they only have the pico and nano ranges.
i can try hero999 idea, but i only have Vdc supply only. can i use it?

For resistors, it's normally fine to just use the nearest E24 value, in fact most of the time even the nearest E12 value will do.
Most types of capacitors are only made in E6 values so just choose the nearest one, most of the time the nearest E3 value (not in the Wikipeda article but the E3 series is 10, 22 and 47) will do.
In this application frequency isn't important so just pick the nearest E6 resistor and capacitor values.
Another option is to use a virtual earth circuit which might be even better if you have a spare op-amp on the IC or you could use a quad op-amp.
