Cisco Catalyst 9300 with different model can be Stacking?

[inamsiddiqui]

Kindly guide me Cisco Catalyst 9300 Series with different model switches can be stacking? e.g., C9300-24P-A can stack with C9300-24T-A?

Can be done: 

• All stack members must be running the same, exact IOS-XE version. 
• All stack members must be running the same "mode":  Install Mode OR Bundle Mode (and not a mix of both)

To stack them, follow the proceedure: 

1. Leave the stack master powered on. 
2. Power OFF the stack member. 
3. Attach the stacking cable. 
4. Power up the stack member. 
5. Wait for the two left-most LED lights to go SOLID ON (and not blinking)
6. Connect the next stack member's stacking cable. 
7. Power up the next stack member. 
8. Repeat #5

IMPORTANT:  
After all stack members are powered up and have joined the stack, do not forget to configure the "priority" (in Enable Mode).

These model can be stack together ( only not possible Cat 9300 and Cat 9300L)
