The LM3671 datasheet provides 4 suggested inductors for L1 for use with the DC/DC converter.
2 of these, the coilcraft LPO3310-222MX, and the Panasonic ELL5GM2R2N are either obsolete, or non stocked at any component suppliers.
Having designed the Panasonic into several designs, the available 2 alternatives are a different package and would therefore require multiple PCB redesigns, which is undesirable.
Other inductors that could reasonably be fitted onto the Panasonic footprint do exist, but these are not "suggested".
For example, is the Bourns SRN3015-2R2M a suitable device for this application?
What are the critical considerations when searching for an alternative part to the suggested inductors?
Are there any other suggested inductors that more closely match the Panasonic physical form?
