Can you not substitute for something else ? maybe BC850 etc.
I see the original is described as a "muting transistor". Is that what your appliation is ?
NXP|BC850C|TRANSISTOR, NPN SOT-23 | CPC

It might help to see it in its intended application...
Must admit it is a device with a different structure to normal n-p-n junctions which give it different properties but things like the reverse voltage rating is something that normally isn't of much concern in audio. 6 volt or 60 volt, its an area we never normally go too.
It is a high gain device, it does have excellent HF properties and it does have an exceptionally low "on" resistance.
If there's room could "leaded" devices be fitted ?
Perhaps approach Sanyo asking for their appointed semiconductor outlets in your country.
This is a bit of slow download (only a pdf) but tells you about the FBET (foldback electrode technology). Sanyo document,
