Digi-key definitely could sanitize/normalize their field values better. But I feel they are intentionally being conservative about touching datasheet values given by the vendors.

In practice (based on experience of selecting electronic components), I don't find this a big issue; after filtering on some other obvious, more binary fields, what left is often a small enough pool of values (like 16V, 16.0V, 12-20V, etc.) to be manually selected/checked.

https://tme.eu does a better job of this. If you enter "16V", it knows to also select the 12-20V ranges. It also works the other way around, you can enter "10-22u" in the parameteric search and it will find both 10uF and 22uF parts.

So annoying that digikey doesn't do this, you have to click each value/range separately.
