Hey

The inductor with part no. XFL4015-471MEC used in this reference design

is not available with my distributor and is also very costly. Could you please

help me select an alternative part from one of the inductors listed here:

Also, what are the most critical parameters that I need to look for in the inductor. Is
an extremely low DCR very important?

Hi Karan,

The critical parameters of a inductor is the saturation current, temperature current and DCR. the current rating should be higher than 4A and DCR should be lower than 50mOHM.

DFE201612E-R47M=P2 and SRN2512-R47M should be OK.
