It looks like it is a capacitor, but I can’t say for sure.
You would have to trace the leads from the unit and see where they go to and check what you find with the schematic.
I have had capacitors in the same cardboard containers before,but that does not mean that yours is a cap or multi caps in one container.
Here are some photos of one that I re stuffed from a Rogers 6R932.
