The new Toshiba replacements are 2SC5200 and 2SA1943.

The most reliable source I know of is B & D Enterprises. You can Google
Bdent.com for their phone number.

The newer Toshiba numbers are also being counterfeited. MCM sells
replacements for the 1302 and 3281, same as Pioneers', made by Onsemi using
Motorola jigs, which Motorola had previously got from Toshiba, so the story
goes.
