Can i use same mosfet number for Upper and Lower side MOSFET in PWM Circuit? Because I always see different mosfet number ( for example Laptop CPU V_Core used MDU1511RH mosfet and MDV1525URH mosfet ) and why?

Both part numbers you mentioned are n-channel MOSFETs, but if you check out the datasheets, they do have different specs.
The MDU1511RH is a beefier, heavy-duty transistor: 2.4mΩ on-resistance, 100A max current.
The MDV1525URH is weaker: 10.1mΩ on-resistance, 13.8A max current.
So why would an engineer ever pick the MDV1525URH? Two good reasons I can see at first glance:
