Transistor equivelent database
« on: April 08, 2020, 10:04:04 PM »
Anybody know of a sight that has a equivalent listing for transistors? Would be quite helpful if they do and post it here

You can use the Digikey shop listing. It's not a cross-reference, but you can use the filters to narrow it down. Are you looking for anything specific?

Thanx Shonver. Wasnt looking for anything specific, yet. Was just thinking of doing another amp build to keep me busy. I did find a a download link of a ebook or scanned in book called Towers International Transistor Selector. But I have now way of uploading it to the site. Could prove quite useful for the forum.

Here is the link for the download should anybody want it. You do have to register, but that shouldnt be a problem, once you registered you can download it.

Now that you asked, I was actually looking for drop in replacements for 2SJ162 and 2SK1058. If anybody could help with that, it would be great  :thumbs:

My understanding is  that different transistors can be drop in replacements in a given circuit and operation level but that does not mean they can definitely  be interchanged in another circuit.


As Shonver alludes to you would select by needed parameters for the application.

Old editions of the Towers book were riddled with errors. I can’t speak for later editions though.

My two favorite places......

el-component.com

and

alltransistors.com.

This covers Bipolars, Mosfets, Zeners, Rectifiers, IGBTs, SCRs, SMD codes, and also has an SMD code Android app for mobile use.

Very easy to use, has a search feature and lists specs, pinouts and equivalents.

Also useful is the HONEY transistor tables which among other aspects references the 2SC/2SA series of Japanese transistors to the BC equivalent which I have found very useful.

For datasheets, alldatasheet.com is very useful.

I remember the days when I longed for the Towers International Transistor Selector digest and another set of two short fat books, slightly larger than an A6 size covering discrete components and IC's. This was before the Internet arrived, and such information was like hens teeth, only the electronic component shops had these books and they wouldnt let a customer touch them and never left them on the counter. How we wanted a set of these books!! The city library had them but it was too far out of the way to go there just to look up a part. I found a set of books about a year ago, but they were in bad condition and passed on the opportunity...with the Internet bubbling over slowly with such information over the last 20 years or so, these books (hardcopy) have been superceded to an extent.


All the best!

Sorry, at the top you can select between signal, drivers, vas and output trannies
