Pinout of 2SC503-R

Here is an image showing the pin diagram of this transistor.

Classification of hFE

The 2SC503-R transistor can have a current gain of 30 to 90. The gain of the 2SC503 will be in the range from 30 to 300, for the 2SC503-GR it will be in the range from 100 to 300, for the 2SC503-O it will be in the range from 50 to 150.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SC503-R might only be marked "C503-R".

Complementary PNP transistor

The complementary PNP transistor to the 2SC503-R is the 2SA503-R.
