充填 means to physically fill a space or gap (e.g. filling a cavity), while 充当 means to allocate funds or resources to a purpose, so despite sharing 充 they are used in very different contexts.

Composed of 充 (fill, supply) and 当 (apply, assign). The combination conveys the idea of applying or assigning something to fill a need.
