In Italian stores i don't find this transistor.
There's a equivalent transistor that i can use?

wijx · 31st March 2005, 02:15 PM

BC550B

Watch the voltage requirements.

Also watch base emitter collector settings, i might not be the same.

Danyele, what is your intended purpose for that transistor? It would be a help answering your question, knowing that.

The MPSA18 in aleph it is used to polarize the output transistor.
The BC550B it's ok?

It workes fine in my Aleph 5

Ok, thanks.
To use this transistor have you changed anythink?

You can order MPSA18 directly from Fairchild. Just go to the Fairchild website and search for MPSA18. The rest is obvious. For sure no fakes, and very good price. Higly recommended.

I do not know if I should say this, but

You can order them as samples from Onsemi as well

Topclass components, no fakes whatsoever. You have 10 (yes ten) orderlines to fill out with your wishes. Just like Christmas, I guess

Be sure to order a few Mur's as well, they come in every flavour

And ofcourse the not so new anymore MJL4281A and MJL4302A with their drivers too ofcourse

I better stop now, Guess I am shooting myself in the foot

It will all in all cost you the royal amount of 14,99$ They also have some nice JFet's and voltage regulators and........ Now I really have to stop
