SMD to Through-Hole Conversion
There are a lot of circuits (a lot) that use J201/2N5457 JFETs. Sadly, these components in the TO-92 package are out of production, and many of those that can be found online are either barely within spec or completely out of spec. So I thought it would be good to have a conversion board to use SMD transistors (that are current production and much more consistent) in through-hole layouts. Just solder some header pins to the holes of this board and you're good to go. I've also done a conversion board for BJTs, as some common through hole transistors are already being pulled from production.

ReplyDeleteThat was fast!
DeleteCool... I was just about to order more of these from eBay but these are way better because with the other boards the pinout ends up being wrong unless you spin the smd SOT-23 part and then it's tricky to solder. Just ordered them..... Thanks again bro!!!!
ReplyDeleteThis is fantastic, thanks!
ReplyDeleteThanks! Exactly what I needed.

ReplyDeleteVery useful. How come you don't have a flanger layout?
ReplyDeleteThere are 2... Click the flanger tag on the left
DeleteBought a heap of these pcbs from http://www.diyguitarpedals.com.au/shop/
ReplyDeleteWas so much easier to match jfets.
Hi! Is there a PDF layout of this for easy scaling? Thanks!
ReplyDeleteIt's in the utility folder in the Transfer Image Library
