TO-92 JFETs - many being discontinued?

time for someone to post a photo tutorial on a diy smd transistor to socket adaptor?

I can imagine a smaller concern stepping in to carry on the manufacture of TO-92 FETs in smaller quantities for the market sectors that still require them. Maybe the product range will have to be rationalised somewhat. There are precedents, such as when Ampex stopped manufacturing audio tape, and everyone thought they'd have to scrap their Studers. It's worth remembering that valves and Ge transistors are still manufactured decades after the big names ceased production.

arghhhhhhhhhhhhhhh don't stop making j201's.......wtf?.........arghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh............... :icon_evil:

They could always be put on a little board like this and used as normal through hole components  ;)

Or mount a header on the board sideways like this: http://www.tayloredge.com/storefront/SmartNixie/IN17b/1357a.jpg 

Annoying and extraneous for prototyping, yes.  Functional and straightforward, yes.

Well, they haven't stopped making them yet, so at least there's still time to stock up.

^yep i have.. ;)


anyone made an smd breadboard?....mine might be obsolete soon...arggggggggghhhhh again.. ;D

The chaepest i  have found the t092 fets are

Rapid have a stock of 2n5457's at £0.05 (5 pence)
http://www.rapidonline.com/SearchResults.aspx?kw=2n5457

Farnell have the J201's at £0.056 (6p ish)

http://uk.farnell.com/fairchild-semiconductor/j201/transistor-jfet-n-to-92/dp/1017715

iv'e bought enough to keep me going as the pedals i build to sell use these.

Edit for price info, forgot to mention you have to but quite a few for these prices

I had ordered like 70 J201's before from Element14 at SGD$0.096 per piece below 10 and 0.087 above 10 and 0.082 above 100 ... naturally i ordered 170 again .

Don't forget BS250 P channel mosfets for Obsidians, BS170 N channel mosfets for Boosters, BOR, etc, and 2N7000 N channel mosfets for having the coolest part number ever.  Once they stop making them, the Mojo will increase significantly.  ;)

BS250's are already long gone  :icon_neutral:
Only 2N7000 and BS170 will continue production for quite some time .

BS250's 20 @ $8.24
That's bloody expensive  :icon_neutral:
I couldn't find it on element14 that's why i said BS250 is no longer in production .
BSS84P is a cheap one for SMD people .
FQP7P06 is the one i bought for non-SMD since it only costs me $USD0.40 .

What about soldering legs onto the SMD Fets?

I know about that , but what if the joints desolder when you solder the legs to the board ? ( Well , leadfree to solder the legs and 63/37 to the board ? )
And i have my stuff really small .
