Philips – datasheet pdf
Im looking for a equivalent to a BF, I understad i could use a 2N is that right? Please also read the last paragraph of the Embedded tag. The other two datasheets are identical in pinning. My circuit does not workand the transistors are definitely good tested them. You can also add a flair tag for your gf494 with your area of expertise by bf4994 on the “edit” button at the top.
I decided to use kspa to replace the bc, and mpsh10 for the bf If in doubt seek an expert.
How to Choose the Best Battery for Your Next Project There are all sorts of batteries out there- this short overview will help you find the right one! High voltages are potentially dangerous. Extreme Amateur looking for an equivalent transistor Posted by superglass sean in forum: Also for advice on electronic component specs pinout, equivalents, timing, signal levels etc.
Want to add to the discussion? 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.
10pcs BF494 Original NPN Medium Frequency Transistor Genuine
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.
If it’s in an RF circuit, then be 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.
Construction Physically implementing a design e. Solar Ask here if designing or repairing your own electronic control circuits. Meta Related to this subreddit.
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.
It doesn’t hurt to double check with a diode check. On topic questions only – see Rule 1. Hifi hookup and buying advice: It’s entirely possible that several different manufacturers have produced transistors labeled “BF”, with different pin-outs.
