Which LT1054 for muzzle

[JetFixxxer]

or does it matter? There's a few listed and not sure if one is better than the other.. I've ordered LT1054CP in the past, but there's a few with LT1054CS8#.. Isn't the letters the material it's made of?

You can usually find info about the suffix in the datasheet.

It could be the footprint, material, temperature rating, classification (commercial, military, healthcare), packaging type, etc.

The LT1054CS8 appears to be an SMD IC.
