Will Ferroxcuble EFD12/6/3.5 SMD former always be in stock?

Hello,
We need to design a single stage PFC’d Offline Buckboost converter LED driver for 30 to 100W. (as much power as components can be fitted inside the small enclosure that we have to work with)
The enclosure that we must fit inside is 140mm x 65mm and just 8mm high. We are only allowed surface mount components inside this enclosure.
We can put the AC filter and MOV, fuse etc, outside of this enclosure. Also, the bulk output capacitance, we have been told, can also be outside of this enclosure.
We need a small isolated flyback bias SMPS inside the enclosure, but the smallest off-the-shelf core and former that I can find in surface mount is the EFD12/6/3.5 by Ferroxcube. (it must be <8mm in height)
Since this is the only vendor of such a part in the world, can we always be sure that it would be in stock?

The answer is no, regardless of what component you're referring to. No component has an infinite life cycle.

There are much smaller flyback transformers available (), though of course they are limited in power.
