What is the difference between BC107, BC108 and BC109?
They share the NPN type and TO-92 package but differ in voltage rating and gain or noise grades. Check the datasheet of the exact variant before replacing one with another.
Can it be driven directly from a 5V microcontroller pin?
Use a base resistor to limit the base current, and keep the collector current within the datasheet limits for your load. For relays, motors or LEDs with higher current, use a separate driver stage.
