MMBF5457’s and where they at?

So, I recently went to stock up on a few items and seemed to be having trouble finding mmbf5457’s. Then I came across a note that they’ve been discontinued? Anyone know what’s going on with these? Is there a spot I can pick up 100+ for a decent cost (-$0.50)? Feel like I’ve been to all the usual spots with no luck.

Thanks!

Edit: digikey says these are a direct substitute -anyone try these in place of the 5457’s?

I know this isn’t exactly what your are after but Fuzz dog has 2n5457 in TO-92 which I placed an order for a load last week. I’m trusting that they are legit but I haven’t received them yet.

2N5457 N-Channel JFET

2N5457 N-Channel JFET These are getting pretty scarce, so here at FD Towers we jumped on an opportunity to get major stock levels while we could. Manufacturer: Central Semicondutor Corp. Package: TO-92 Download DATA SHEET

Until very recently, GuitarPCB had some NOS 2n5457s, but have gone dry.

I thought about buying some, but didn't because I figured the the smd versions would still be around for a while.

Update: looks like pedalhacker still has some in stock.

Oh Jesus, I can only imagine. I knocked one off the bench last night, didn’t even bother looking for it. If I have trouble finding a dropped ge diode, I’m never gonna find an smd fet.

Awesome, that’s exactly what I needed! Thank you very much. I went through four pages on the google and nothing…. Out of curiosity I noticed these have an “LT1” at the end, I’m guessing they’ll work for our needs? Thanks again!!

Edit: I quickly scanned through the data sheets and they seem to jive. Maybe the LT1 is ON Semi’s code and the regular 5457’s are FSC. Also, now that I google MMBF5457LT1 I’m finding a lot more in stock in other sites. Maybe it’s just FSC that’s discontinuing them. Hopefully ON Semi’s are just as good, mojo and all. Although doesn’t ON own FSC?
