Useful - Transistor Equivalence Cross-Reference websites list

[Whoops]

Hello,
in many repairs and DIY builds we find the need to know an Equivalent transistor to replace a failed one or for a new build.
Back in the day people had books with charts for transistor equivalents.
I found many sites and sources that you can easilly do that nowadays and are pretty usefull,
use them all the time.

Here is the list

Transistor Equivalence websites:

Thanks! Seems like you can download the pdf on the third link here:

Audiokarma or one of the sites also has an excel spreadsheet you can download with equivalents, but the last time I looked, it was badly out of date. all of their suggestions as replacements were also no longer being made.

Another useful document for fast and easy substitution,
it's made for the guitar pedal DIY crowd, but usefull for us also

Alltransistors.com are a good quick reference - once you enter the transistor number and choose the variant if there are any, at the bottom of the page is the link for equivalents which you click on - this gives you the choice to change specs for your substitution including packaging. Below that link are listed datasheets.

I really dislike that site and I don't recommend it at all.
It already gave me wrong information in the past and constantly keepd give you results for transistors that you will never find around.
It's not that good

Personally I think the links I provided in the first post are much better, and those are the ones I recommend.

Cool - good to know. Thanks

I'm not keen on their suggestion of an OC44 instead of an AC128!
