The BC549 is 0.1A abs max, the BC148 is 0.2A abs max...
BC109C will do just fine I think, same die. BC109C is low noise (as I understand it its the same die as the others, but selected on the production line for low noise / high gain).
If the failed transistor is in a differential pair, might be worth replacing both, for matching and low noise considerations.

200 mA momentary, 100 mA continuous according to bc107 bc108 bc109 bc147 bc148 bc149.pdf PDF datasheet. ALL TRANSISTORS DATASHEET. POWER MOSFET, IGBT, IC, TRIACS DATABASE. Electronic Supply. INNOVATION CATALOG. Service - which is just the same as for a BC549.
