It looks like a pretty generic NPN transistor, so unless the circuit is picky, I’d expect pretty much any generic NPN would be br494, so long as you pay attention to what the circuit demands are. Theory General electronics theory eg: Home audio repairs especially for vintage gear: A subreddit for practical electronic engineering questions: Facial Recognition Increases Autonomous Vehicles Safety Facial recognition, which has many applications in security and biometrics, bc494 recently been drawn to a new realm of application: The famous TO package, where the same transistor did indeed nave several different pinouts.

General electronics theory eg: Please check all tag descriptions before choosing one. Back to my question, I looked at the spec sheets and it looks like the transistors I used should work. You must categorize your question by clicking bc494 ” add tag ” flair button after posting it. Extra rules apply to questions on vehicle electronics – please read before posting.

For general setup questions, ‘how tos’, specifications and what-connects-to-what etc. If in doubt seek an expert. Hifi hookup and buying advice: Buying and general tech. Second and third links shows the same pinout: Commercial buying, selling, consulting jobs: No worries with that stuff where I live. Fixing a commercial product.

Not sure if your question is on topic? Gustavo Litovsky 6, 2 15 I did some hunting for info, and yes, I was correct, you can use the mpsh10 rotated deg in place of a bf like I did.

The Philips datasheet shows the transistor from the bottom the side where the pins come out of the package. Meta Related to this subreddit. B4f94 if you don’t have that, use the diode checker, there be junctions in there! Extreme Amateur looking for an equivalent transistor Posted by superglass sean in forum: I think you may just have to test each lot of transistors.

No generic ‘which is best’ and ‘where to buy’-type questions please. Want to add to the discussion? Please tell us roughly where you live – especially if you are bf94 for a local supplier!

Do you agree or disagree. 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 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.

Alternatively, figure out who specifically manufactured the devices you have, and get their datasheet. I decided to use kspa to replace the bc, and mpsh10 for the bf First, check out our list of national and global suppliers. The BFxxx range is ‘small signal rf’ stuff, but quite ‘old school’ so, depending on circuit, as you bv494, modern alternatives are not hard to find.

What is this Identifying an electronic component in an electronic assembly. Ask the mods before posting. It might sound stupid but I’m in a real doubt since many datasheets disagree regarding the BF transistor pinout.

Note the dedicated subreddits below eg: First link has no datasheet at all, its just a list of some possible substitutes with strange information from strange sources. Yes, my password is: Modification Modifying an electronic circuit or product at component level. Lighting, audio, wiring, fixing etc.

If you cause interference with FM radios or with airplane communications then you will be in for BIG trouble. The other two datasheets are identical in pinning. I’m no expert at transistor selection, but I don’t see anything in the datasheet that screams out “I’m special!

It is a small transmitter. We cover designing or repairing solar-related electronic circuits control and management systems.
