Re: 2sc930 equiv
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 |

Re: 2SC930 equiv?
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. |

Re: 2SC930 equiv?
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.

Re: 2SC930 equiv?
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.

Re: 2SC930 equiv?
SS9018HBU is On-Semi's lead free version.
As Maarten said, same thing. |
