Will a 2n3906 work in place of a BC328?
Is there a better match for the BC328?

Thanks

 

The BC328 is PNP while the 2N3906 is NPN, so that would not be much good.
Here is a list of some better substitutes:

2n3906 is a PNP type.

2n3904 is the NPN type

 

Not a very good match, but whether it would work acceptably depends a lot on the circuit in which the replacement is to be used and which version of the BC328 you want to replace.

Hi,
2n3906 and bc328 are both pnp as per datasheet of see (alldatasheet.net).

You can experimenting how to substitute transistor,by first getting the data of each transistor spec.
As per given like the alldatassheet.net.
Second see each parameters how it differs. select the appropriate that have a good parameters.

Lastly can you give your circuit design where we can analyze too.

I attached a picture of the circuit. It is for the LOPT/FBT or Blue ring Tester found here: http://www.flippers.com/pdfs/k7205.pdf
Another version by Anatek here: https://www.flippers.com/pdfs/BLUE_rt_assembly_manual.pdf

You could use just about any general purpose PNP transistor.

2N4403 might be closer considering collector current. If you keep the current down around 100 mA a 2N3906 would be okay. The pin out might be different between the BC328 and the 2Nxxxx stuff. Check on that.

 

BC328 was overkill. Collector current is less than 5mA.

Then 2N3906 will work but the pin out is reversed.

 

Thanks for all the help, I appreciate it.

Hi,
Thanks for sending a link for the manual.

Thank you for posting that link. I have bookmarked that page for future use.

No problem. Maybe someone else will want to build it.

A super cross reference, thanks. But at a collector current if only 5 mA he really didn't need a BC328 equivalent.
