Mar 12, 2. Alternatively, figure out who specifically manufactured the devices you have, and get their datasheet. Use this tag if you need help sourcing electronic components or parts related to a circuit build or repair.
If it’s in an RF circuit, then br494 sure the f T is at least MHz, and that it has a low C re ; if it’s switching current, then make sure the replacement can handle at least 30mA. Yes, my password is: It might sound stupid but I’m in a real doubt since many datasheets disagree regarding the BF transistor pinout.
Back to my question, I looked at the spec sheets and it looks like the transistors I used should work. Electrical wiring home, industrial: Home audio repairs especially for vintage gear: Modifying an electronic circuit or product at component level.
The BFxxx range is ‘small signal b494 stuff, but quite ‘old school’ so, depending on circuit, as you suggest, modern alternatives are not hard to find. Off topic questions, and those fully answered in the Wikimay be removed. Mar 12, 3.
Datasheets are perfectly fine. Commercial buying, selling, consulting b4f94 Commercial stuff selling, paid work etc. OK, go right ahead; you ARE ‘troubleshooting’! Identifying an electronic component in bf49 electronic assembly. Modification Modifying an electronic circuit or product at component level. It looks like a pretty generic NPN transistor, so unless the circuit is picky, I’d expect pretty much any generic NPN would be fine, so long as you pay attention to what the circuit demands are.
I decided to use kspa to replace the bc, and mpsh10 for the bf Electrical installation work and parts, home lighting inc.
Not for general ‘modding my PC’ etc. High voltages are potentially dangerous. Second and third links shows the same pinout: Mar 12, 4. Do you already have an account?

Solar Ask here if designing or repairing your own electronic control circuits. We do request that anyone asking about parts tells us their general location so we can help with local supplier, so perhaps subby will come back and tell us about the intended circuit and where they are. For general setup questions, ‘how tos’, specifications and what-connects-to-what etc. It is a small transmitter. I don’t trust your 2nd link, it isn’t an original datasheet and it looks like someone manually selected a standard figure that often but not always goes nf494 this package.
No worries with that stuff where I live. Lighting, audio, wiring, fixing etc.
My circuit does not workand the transistors are definitely good tested them.
