What is the difference between a stack decoupler and a stack separator?
-
So what is the functional difference between a stack decoupler and a stack separator? Why might I use one over the other? In what cases would I want to choose the TR-18D Stack Separator over the lighter TR-18A Stack Decoupler?

The Stack Separator decouples from both the child and the parent node whilst the Stack Decoupler remains attached to the child.
Why might I use one over the other?
Situations where you are separating satellites, rovers, probes or other payloads and don't want the Decoupler still attached.
