200 nanofarads at 400 VDC is an exact equivalent.
But seriously, a value of .2 uF is a bit uncommon. A more ordinary size is 0.22 uF. Or, you can parallel-wire two 0.1 uF caps to obtain 0.2 uF.
The job a cap is doing in a given circuit determines the latitude one has in replacing it, value-wise. Caps used in RF resonant circuits or for timing circuits must be replaced with the exact value of the original. For RF bypass or for power line filter caps, the value can usually be doubled or halved from the original spec without significant impact. For audio coupling caps, it is a little more important to try to match the original cap's value, although it is not as critical as an RF resonant circuit application (the audio circuit will still work, but the tone quality may be altered).
