BF Transistor – conflict in pinout – Electrical Engineering Stack Exchange
Project Idea Scoping out an idea based on electronic components. OR if you don’t have that, use the diode checker, there be junctions in there! Quote of the day. Want to add to the discussion? Solar Ask here if designing or repairing your own electronic control circuits.
I don’t trust your 2nd link, it isn’t an original datasheet and it looks like someone manually selected a b494 figure that often but not always goes with this package. 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.
Not for general ‘modding my PC’ etc. It was the RF amplifier in an FM car radio.
Extreme Amateur looking for an equivalent transistor Posted by superglass sean in forum: I decided to use kspa to replace the bc, and mpsh10 for the bf Theory General electronics theory eg: Welcome to Reddit, the front page of the internet. Home audio bf4994 especially for vintage gear: 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.

Parts First, check out our list of national and global suppliers. My circuit does not workand the transistors are definitely good tested them.
Home Questions Tags Users Unanswered. Datasheets are perfectly fine.
Transistor equivalent for bf494 & bc548
It should be correct hopefully. Let me know if you also think this is OK. Not sure if your question is on topic? No, create an account now. If in doubt seek an expert. Construction Physically implementing a design e. Mar 12, 1. High voltages are potentially dangerous. Become a Redditor and subscribe to one of thousands of communities.

The BFxxx range is ‘small signal rf’ stuff, but quite ‘old school’ so, depending on circuit, as you suggest, modern alternatives are not hard to find. Buying and general tech. First, check out our list of national and global suppliers. I’m no expert at transistor selection, but I don’t see anything in the datasheet that screams out “I’m special!
It might sound stupid but I’m in a real doubt since many datasheets disagree regarding the BF transistor pinout. You want the ‘Repair’ tag. If you cause interference with FM radios or with airplane communications then you will be in for BIG trouble.
