can pic18f66k22 and pic18f66k90 be used interchangeably?

can pic18f66k22 and pic18f66k90 be used interchangably without changing PCB design ?
almost pin diagram is same
both have same features exept k90 has aditional LCD driver feature.

any suggestion would be helpful

thank you.

I think they can be used alternatively because pin diagram is same almost.

Correct. Apart from the Segment LCD features of the PIC18f66k90 they are virutally the same, PIN compatible. So as long as you're not using the Segment LCD features, you shouldn't have any problems.

thank you bigdogguru!

I queried it because part pic18f66k22 is in production at microchip and not available at digikey
so if I can use pic18f66k90 insted of that
