The Hirose DF9-15P-1V(32) is a 15-position, dual-row header with center strip contacts, part of the DF9 series. The header is surface-mount (SMT) and mates with the matching DF9-15S-1V(32) receptacle to achieve a fixed mated stacking height of 4.3 mm.
The 4.3 mm mated stacking height is fixed; if your board-to-board gap is different, this header won't fit without a spacer or a different stacking height variant.
