Viceroy SMD JFETs

[uranium_jones]

So I am looking at my Viceroy board and I am seeing that the spots for the PF5102 JFETs are tied to identical pads to place SMD components. But so far my internet searching suggests there's no SMD version of the PF5102. Is this true? And if so, what should be going there?

I really want to try SMD and this would be a good excuse.

2n5457 is a great and common substitute so mmbf5457 is what you would want

One vendor I can find that has them in stock, and more expensive than I was expecting. Sounds like that's the part I need.

Yeah, that's it. I was hoping it would be closer to this price:

Wow... $0.99, quite expensive. My last purchase of the MMBF5457 from Tayda was $0.32 for a piece (in March).
Looks like MMBF5457 is out of stock or "discontinued" from most of the big sellers. I was going to buy 200 or 300 pieces from the Mouser but they vaporized from my shopping basket.

its off the smallbear site as well. My guess is the shortage has made all the big companies snatch them up and now us peasants are left waiting for productionto get up and running

I certainly hope it's that rather than a discontinuation. I don't mind waiting a finite amount of time. At least Mouser says "Factory Special Order" instead of "Obsolete"

Heads up, I just ordered some 5457s from DigiKey yesterday

Man those little suckers are a little hard to get ahold of right now. If you can find them in any format or equivalent I would grab ‘em.
