Huawei UBBPd5 — universal baseband processing unit
The UBBPd5 is the mid-tier d-series baseband board, carrying GSM, UMTS, LTE FDD and NB-IoT. It is physically identical to the UBBPd6 in form factor and port count, which is why the two are frequently offered interchangeably. They are not interchangeable: the d5 has no LTE TDD support whatsoever, and carries roughly half the capacity of the d6 in every other dimension.

No LTE TDD. This is the single most important limitation against the UBBPd6 and the most common cause of a wrong order in this family.
