BS170 same as BC170?

[audioguy]

Im building a trem from Topopiccione and dont have any BC170s- but Ive got plenty of BS170s. Can I use the BS's or should I find another sub for the BC's?

Thanks!

the BS is a FET. The BC is not.

www.datasheetarchive could have answered this for you

I googled them both but couldnt find much on the BC... guess I gave up too quickly.

Thanks for the help... Im off to find another replacement for the BC170s.

BC170 NPN, T0-106 case, hFE 35-600 at 1 mA, suggested replacement is BC548 (from my old replacement guide from 1980)

http://www.datasheetcatalog.com is another good one for info.

With such a wide Hfe, it looks like a wide variety of small signal NPNs should do the job. From the 2N family of part numbers, you could try the 2N2222, 2N3904, or 2N4401 for starts.
