TIDA-01228: tidud25a problem regarding LC sensor

Can we replace the inductor value from 235uH to any other value like 220uH.  Or, we need to use only 235uH. Because the 235uH from gemphill technologies is not available from regular vendors like mouser, digi-key.

Please suggest.

    Hello Sai, the author of this design will be best able to answer your question. He is unavailable this week, though. He can reply to your question next week.

    Yes, you can use 220uH or similar value. Keep in mind that the oscillation frequency will lightly change due to the different inductor, so you will need to adjust the number of oscillations and the timeout period.
