sachu is on target... If you look closely at this (click through 2X), my 2nd cth, think you see the 2nd coil you listed:
It's working fine for me BUT it was a heck of jam, leads didn't line well, 1N5820 was tricky to fit next to it, toroid is better/preferred, etc, etc. I only used it because it was on hand, I had the LM2595 & I could sufficiently test (scope) that it works. If one took the chance on using such a coil, they'd want to sub 1N5818 for 1N5820 to ease the fit.
You need to source the LM2595 anyway & that source might have the proper toroid 220uH 0.8A or higher (I linked to an Aussie source back in this thread).
Note: Clearly any complications from deviations from the published BoM (or parts incl w/kits) fall on the builders hands
Be very sure of what you are doing.
