Yes. They'll be interchangeable. By the way, don't let the "ESP" in Delvac 1 lead you astray. There is no more "Emissions System Protection" in Delvac 1 ESP than there is in T6. ESP is something Mobil tacked onto the Delvac 1 name when CJ-4 came out, which was when SA was reduced to 1.0 or less. Delvac 1's SA will be the same as just about every CJ-4 or CK-4 lube out there.
Even for phosphorus levels, I wouldn't worry. Delvac 1 LE 5w-30 in E6, low phosphorus, was on Ford's "E" list as approved. So, either Ford's specification was wrong or Ford's current diesel has problems. A low phosphorus lube is specifically on the approved list that covered your engine.
I'd grab the cheapest available lube on the shelf in the appropriate viscosity and go with it.
