2SK118Y Replacement?

[Bucksears]

I've got an 'as-is' Boss CE-5 incoming, and the issue it's having is most likely due to the switching JFETs. The analog CE-5 uses two 2SK118Y JFETs, and I'm having some difficulty finding those.
Is there an as-close-as-possible replacement for those? I'm afraid I'm not familiar with which characteristic (Vgs?) needs to be the same to match functionality.

The 2sk208 is the smd equivalent of the 2sk118 and it's still in production. Both mouser and digikey carry the 2sk208-Y (as does aliexpress, not sure if it's worth it, though). You could buy it and use an adapter board

Had some time tonight to research it, and (oddly enough) it appears that the (older) SK30ATM-Y has the exact same specs as the 2SK118Y.
I can pick up the former at Tayda - I'm going that route.

That's true! I had forgotten about the 2sk30! It's just a different package, if I'm not mistaken

Nope - same pinout and everything. I'll report back with the results.

You're right, pinout is the same, but I think they have a different footprint, like those two:


The sk118 looks like the one on the right, and I think (never had one in my hands, though) that the sk30 looks like the one on the left

I can work with that.

I can work with that.

How'd it go?

 

[Bucksears]

Sorry I never replied back.
Yep, the SK30ATM-Y worked. Still think I got this CE-5 at a steal, considering it's basically a 'time capsule', mint specimen that's dated from July 1994. The chorus works just fine, but the EQ is very subtle and I can see where the 'deep' mod can be desired.
Unfortunately, I've got bills to pay, so it's up on my local CL at the moment.

Here also offers 2sk208 with part details. mouser and digikey is ok.
