2sc1419 is relatively slow and low wattage for that size case, which mean almost anthing will work. Kenwood used them a lot as voltage rgulator pass transistor.
Normally used as a pass transistor for voltage regulator or low power amplifier outputs. Bottom line is about anything will work. KSD526 or ksc2073 are excellent replacements.
TIP29A would be about equivalent. TIP31A (or B or C) or TIP41A (again or B or C) can be used but higher power. No longer available but equivalent 2sd330. Higher wattage 2sc798, 2sd313, 2sd613. Many more are possible. My 2 cents.
