What devices commonly use it
Slim key fobs, compact fitness gadgets, and small remote controls may be designed around CR2016 thickness.
What it's interchangeable with

What it's NOT interchangeable with
It is not interchangeable with LR44/SR44 button cells due to voltage, shape, and chemistry differences.
Common mistakes
- Using CR2016 as a drop-in for CR2025 without checking contact reliability.
