But some devices, particularly transistors are available in several pinouts for what is electrically the same device.

BC182/BC182L (NPN) and its complimentary device BC212/BC212L (PNP) are in TO92 packages but with different pinouts.

The non "L" version is TO92-4 EBC
The "L" version is TO92-1 BCE
