Sorry, epcos sold ceramics business, and was itself swallowed by TDK.
If looking for X5R and X7R cer caps, visit vishay, kemet, taiyo yuden,
murata and others instead.
This special material specification is well hidden at the official
Those are high grade ceramic dielectrics, realtively cheap, not
necessarily space qualified, only automotive, and especially not an
exotic component anymore.
If Tek had problems with tantalums in the past, they either have chosen
bad suppliers (reliable / safe production is critical), or that was at
the time, where the failure mechanisms were not understood well, or they
have ignored application hints.
Today, its possible to use Tantalums safely even in automotive
applications, that goes for ceramics also.
Its - as always - a question of component knowledge and reliability
