JFet question

[megatrav]

Hey!
I’m building a Tweedman (Catalinbread 5F6). I’ve done some searching on this forums and some
other places but I’m having some trouble finding jfets, through hole or SMD.
I would prefer through hole parts because I’ve never tried to solder SMD, but I’ll take what I can.
Most of the older threads mentioned parts that I can’t seem to find anywhere, including mouser.
Any help is greatly appreciated. I’m definitely open to any alternatives that will work.

thanks!

Try PN4393 might be easier to find, you can also type MPF4393 into the search bar and many threads talk about substitutes

Aionfx.com has mpf4393s

MPF4393 JFET, Set of 5 - Aion FX

(@Harry Klippton beat me to it)

 

[music6000]

Aionfx.com has mpf4393s

MPF4393 JFET, TO-92

The MPF4393 is an N-channel JFET, most notable within the DIY community for being the primary JFET used in Catalinbread® pedals from 2013 onward.

Thanks for the link to the Aion. I had no idea they were so expensive!

I found these on Mouser. I think I might try those.

Would these work?

Transistor FET 2N5484

Guitar pedals, pedal parts and electronics.

Probably, but you may have some noise, I'd go with Aion ones, a buck a piece ain't that bad if you get the others and don't like them

Hey, That's 5 for $5.00, No one else is even close!!!!!

I bought 20 of em from electronic goldmine at that price a couple years ago. Should have bought more

My bad. I thought they were $5/each

I just bought 30 and don’t have a project that uses them currently

Glad to know I'm not the only one like this

Indeed. I buy leaded JFETs whenever I see a good deal.

Your best sub for MPF4393 is PN4393 from Mouser. Exact same specs and quantity discounts.

I saw those, just wasn't sure I'd ever need 100 of them

Then buy 10 or 20. Just how serious are you about this addiction?

Bought 30 from Aion

They go quickly when you're building pedals based on Catalinbread designs.
