The Spare Parts crate does indeed have spares...or at least it started out with them a month ago. However, unless you're using two digital sidecars in your robot, you should have a spare already. The FRC-cRIO comes with two of them.
If you can't find yours, it's extremely likely that at least one team at the regional will have both installed but is only using one of them. You'd be helping them save weight by borrowing the one that isn't connected to anything.
