    Hi Steven,

    We've only done our testing with this particular inductor and can't guarentee the performance of another. However, there are similar inductors but they have trade-offs. For example, LPC4045ATED470K is larger in size and only rated up to +85C but offers a lower DC resistance. SDR1307A-470K is another one but it is about 2-3 times larger.

    Another option might be to look at the TI Design of the 933, which offers a slightly different network and inductors. All the information is provided on the page below.
