replaceable
Can be swapped
Replaceable describes something that can be substituted or exchanged for another of its kind: The battery is replaceable.
When applied to people, it often carries a dismissive edge—suggesting someone lacks unique value: No one wants to feel replaceable at work.
The word implies interchangeability, whether of parts, products, or personnel.
