Hello all!
I'm trying to assemble a custom PCB for a wireless charger circuit I've been working on (http://www.idt.com/products/power-management/wireless-power/wireless-power-receivers/p9025ac-r-evk-wireless-power-receiver-reference-solution (http://www.idt.com/products/power-management/wireless-power/wireless-power-receivers/p9025ac-r-evk-wireless-power-receiver-reference-solution))
The coil that they have in the BOM is not available at any of the US manufactures:

I looked on Digikey, and found this coil:

Could I use this to replace the other coil, or will it not work properly? The inductance value is the same, but not the resonant frequency or Q Miniumum. I'm not sure if I should change the oscillator circuit or the coil, any suggestions? Thanks!
