Scroll down and click the 5V output, its still way better than mouser/newark/etc. Maybe you can suggest to them to support quotes in the filter. [...]
I choose Output Type: Fixed, Number of regulators: 1
Here's the Digikey picklist of {censored}:
Voltage - Output (Min/Fixed)
...
4.9V
4.9V (5V)
4.95V
5V
5V, 3.3V
5V, 5V
5.05V
5.1V
5.14V
5.15V
...
Most of the values are silly. What do the mystery brackets mean and why multi-value? I've always wanted a 5.14V regulator not a 5.15V one
They don't understand there is a nominal value with a tolerance window. This is just for a linear voltage regulator. They've been around over 50 years and a very rudimentary search returns silly results that take time to manually filter out in my fuzzy head.
Mouser's picklist:
...
4.6V
5V
5.05V
6V
7V

[...] I have had CR2032's pop and burn up, its very very rare but happens. A few out of 20,000+ cells, not sure of the exact cause.
Anyway, they don't want to ship lithium batteries to Canada due to the additional hassle it requires, which is completely fair. Google TDG regulations.
If you actually want to purchase CR2032s, either get them from Ebay from a canadian seller or from Amazon, then they can ship local mail.
I remember hazloc testing CR2032 and they hard short them and nothing happened that could start a fire, so the agency said. I think for Zone 2.
Shipping I hear the barrier is due to the complex paperwork to get them into Canada. Unfortunately grocery stores ask $7 for a CR2032 (Energizer) now and price-gouging for brand-name coin cells is rampant.
