Can you use J211's in place of PF5102 transistors?

[Barnshart]

I am building the Parentheses and while shopping for parts I could not find any PF5102 in stock. I did a Google search for some alternatives and I believe I found J201's as a possible substitute.

However.... Looking at my most recent order history from Tayda I believe I accidentally ordered J211's and not J201's. So... Will those work in place of what I meant to buy? I'm super new to building and simply don't understand how to determine this stuff on my own.

Thanks in advance to anybody who chimes in!

The general idea is to compare the data sheets and how the JFET is functioning in the circuit in order to determine if you can swap one JFET for another. However, I don't know enough about JFETs to do that, so I am chiming in just follow this post and see what someone else has to say, as inevitably someone that knows will drop in and educate us.

They're just being used as source followers/ buffers in the Parentheses, so your J211s should work just dandy.

Thank you very much for that!
