Interchangable?

I just noticed the pinouts of TDA2050 and LM1875 are the same...

I just finished designing a PCB for the TDA2050 with a +-22VDC supply.

Am I correct in stating that I could use the LM1875 IC as well.

I'll put a 1M resistor on the PCB for the LM IC as shown on the Datasheet.

tda2050 was one of the chips suggested at the beginning of cloning.
