EOL Taiyo Yuden CKP20162R2M-T 2.2uH inductor in 1.8V buck supply, alternates?

I am trying to release a DW1000-based design to production.

In this design, the 1.8V TI LM3671MF-1.8 based switched-mode-power-supply (SMPS) includes the Taiyo Yuden CKP20162R2M-T 2.2uH inductor, which my client recalls was specified in the reference design from DecaWave. However, I cannot confirm that, because I cannot find a DW1000-based reference design schematic.

As it turns out, the Taiyo Yuden CKP20162R2M-T is going EOL. It has a very small footprint for 2.2uH, 1.2A and 140mOhm, and I cannot find another similarly-spec’ed inductor, with such a small footprint.

A) Is this part suggested by DecaWave for use in the 1.8V SMPS?
B) If so, can anyone suggest an alternate for this inductor?

Best regards,

Hi Kevin,

For the DW1000 based product called DWM1001C we use indeed LM3671MF / CKP20162R2M.
For our DWM1004C design XC9258B18CER-G (Torex) and DFE201612E-4R7M (Murata) .
So If you want to stick to TI LM3671MF, I suggest you contact TI .
Hopefully of some help

Thank you very much, Leo. I’ll chase that down.
