Default 2SC930 equiv?

Hi
Does anybody know please a good equiv ?
Used in a Sony shortwave radio that's fussy on gain
Needs to have hfe of pref 120
It's in the rf oscillator circuits etc only up to sw freq
Thanks
Pete

It's just an HF transistor, I've seen quite a few of them in Japanese gear. I've never had to change one, but the usual standbys of MPSH10s or 2SC2999s should be OK. In fact any general purpose type will probably work.

Sanyo themselves recommend a 2SC2839: http://www.alldatasheet.com/datashee...O/2SC2839.html

S9018H is another option - note, the H in the part number is important in this context (hfe range).

Pinouts are different, B & C are swapped.

Can't you just experiment with whatever you've got? If the circuit is very fussy about gain (which seems unlikely) then you may need to hand select anyway.

Are they all 2SC930s? If so, it's probable that they're just being used as general purpose types. I've come across that before. If so, then you'll find the standard 2N3904/BC548s will be fine. Watch out for the leadouts though.

Should be the same. A classic Hong-Kong type. The important part of the number is 9018H.

SS9018HBU is On-Semi's lead free version.

As Maarten said, same thing.
