What matters for this question

A Waterpik legacy Sensonic compact head and standard head share a documented legacy model list, but the STW series uses a different replacement family.
Compare the exact manufacturer part number, head size and compatible-handle list rather than treating compact as a cross-generation adapter.

How to apply it

Within one documented system, compare which handle models the compact and standard variants list. A smaller head may help positioning, while a larger head covers a wider area per pass. Neither size changes the need for correct connector fit, gentle pressure or interdental care.
