Is there a lot of difference in the BC560 to 560C or B transistor?
In Brazil I only found BC550, BC550b, BC560, BC557 and BC557B.
Can I use BC550 and 560 (B) to replace BC550C / 560C?

B and C are the Gain/HFE ranges:

  • "A" indicates low gain (110 to 220, typically 180) at 2 mA collector current,
  • "B" indicates medium gain (200 to 450)
  • "C" indicates high gain (420 to 800)
