Depends on the application. But in stompboxes, where we use so many parts in their non-linear region, I consider nothing sacred.

As an example the 744878101 is quoted 2.16 eur/pc at Mouser.

They look like they're intended for use in low power flyback converters. In that case high frequency response shouldn't be a problem, but you'll quickly run into core saturation issues at low frequencies.

Any idea where to buy the LTHZ?
