When looking at the [CSM1 series](https://www.digikey.com/en/products/filter/crystals/171?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogDMAbHGBALqEAOALlCCAC%20woA) of crystals from [Cardinal](https://www.digikey.com/en/supplier-centers/c/cardinal-components), you may find some part numbers with suffix “A5” . The datasheet does not call out a meaning for this suffix.

Suffix “A5” calls out the operating temperature at -20 ~ 70°C.

Here is a part breakdown for CSM1 series of crystals from Cardinal’s datasheet.
