LM3478: Doubts on the selection of Mosfet based on Webench reference design

Part Number: LM3478
Other Parts Discussed in Thread: CSD19538Q3A

Hi There,

I have a reference circuit for LM3478 from Webench based on inputs. It needs to operate in range of Vin = 15 - 32 VDC and Vout=24VDC at 0.6A. The design is okay for me but the mosfet (CSD19538Q3A) in that design is rated at 100V/15A, this ratings seems way more than the required operating specs. So can I just select a mosfet (SI2392BDS-T1-GE3) around 100VDC/2A ?

I need to select a fet which is small, easily available and have pin to pin alternates available, the suggested mosfet has a package that won't be that easily available.

Please let me know.
