The pinout is the same but the characteristics are quite different. The J113 is much more suited to this job, but the J201 will still work to some extent. Bumping the supply voltage to 18V could make it usable with a J201.

what is the best JFET fo replace it?

If you can't find a J113 a J201 is the next best choice, in my opinion. I'm not terribly familiar with many other JFETs... maybe somebody can suggest another with a low VGS(OFF).

Replace it with MPF102.

I found this schematic... does it match the above docs?

Yes, but this schematic include led indicator on for the gate (on/off).

someone could work with replacement J113?

TL022 may be replaced by TL072?

In my last batch of 2n5457's from Tayda, i had about 40% with a VGS(OFF) in the 0,70V-0,79V range, and about 10% with a VGS(OFF) less than 0,20V. Only 3 or so from a batch of 100 had VGS(OFF) above 1V
I don't know if that's low enough?

Nobody answered...
What's the difference between DOD FX30 and DOD 230... Both of them are Noise Gates, we know, but... What's the difference between???

According to this website, the FX30 is based on the 230. The FX30 was then succeeded by the FX30B Gate/Loop. Here is the official schematic for the 30B. I don't know anything else about the differences between them.
