[Banishment][1] requires a specific component

> An item distasteful to the target

So does [Summon Greater Demon][2]

> Vial of blood from humanoid killed in past 24hrs

I thought I had seen this question here before, but I couldn't find it to double-check, so I'm asking again. 

**Can specific components with unique conditions be replaced by a component pouch or arcane focus?**

My interpretation is that cost isn't just gold, it is any sort of condition on the item (so, distasteful items or blood with timer requirements have a cost). Therefore, both these spells would require specific components to be cast. Is my interpretation correct?
