What D/5 is made of

D Major (2nd Inversion) (D major (2nd inversion)) is built from the notes A, D, F#, with the interval pattern 5, 1, 3. A common major (2nd inversion) chord across many styles.

Stack 5, 1 and 3 on a root of D and you get A, D and F#. That interval recipe is what makes the chord a major second inversion chord — move the same shape to another root and the character travels with it, which is why C/5 sounds like a transposed D/5.
