Default Is H945P the same as 2SC945?

I have a bunch of H945P transistors in my active PC speakers. The system died on me some time ago and I want to see if I can repair it.
I can't seem to find anything on this particular transistor so I'm not sure if the 2SC945 is the equivalent.
If some of you more experienced people can help me out here?

Regards

I don't have the answer, but I would suggest that the case style of the part tells you a lot...a 2SC945 is a simple, small TO-92 transistor that is rated at 60V, 100mA, and 250mW. Now, if this H945P looks like a TO-220 power transistor (for instance), you KNOW that they aren't equivalent.

Walter,

the H945 is a Chinese version of the 2SC945, H stands for Huashan.
P is the Hfe class, so get a 2SC945-P by NEC or whichever other manufacturer.

Post Drek: you can download the H945 datasheet and compare it with the Japanese version yourself : ECCO, RAGAZZO

Thanks guys.
It is indeed a TO-92 device EchoWars.

Thanks for pointing me towards the datasheet Jacco.

Problem now is to find a supplier who has these little buggers available. Farnell, RS, Conrad, Mouser and Digi-Key don't have them.

Regards

Duuh,

C945 , 25cts each and a beer in Maastrich.

Give me a call for the diaper.

That's an N type they sell and not the P type that I was looking for, but thanks anyway.
Don't quite understand the diaper thing, is that a sarcastic comment of some kind?

Regards

N stands for NPN.

An N Hfe class does not exist, Zunne.

The shop in Aalst has the P, here
Just fun, sarcasm posting is for chicken sheets.
