BQ51025: what is the alternate for receiver coil

Part Number: BQ51025

we are using BQ51025 in one of out product and we have used the "IWAS4832FEEB150J50" (15uH) receiver coil in design as this very same coil was used in "BQ51025EVM-649" development kit.

this coil has been obsoleted and please suggest the alternate part. 

we have found the "IWAS4532AGEB140KF1" (14 uH) as alternate part is this part work with this chip without degrading the charging time and current?

    The DCR for the IWAS4532AGEB140KF1 is a little high, higher current will show more heating and possible thermal problems.

    Another option is the Wurth Electronics 760308103215, the DCR is low and similar to the original coil.  In stock at Digikey.
