TI recommended IHLP5050FDER5R6M5A Inductor (It is too big to my board), It is possible to use 744316560 (Wurth Electronics) Inductor?

Vin= 4.5 to 12V

Vout=30V

I= 0.6A

According to the calculate, you need to use a >6A current rating inductor. Please attached the datasheet of the Wurth inductor, I can't found it.

The Wurth inductor's currrnt rating is too small, suggest they use coilcraft one, XaL7030, please check the5140.xal7030-102ME.pdf attached DS.
