The 14mm and 15mm mated stacking heights are the z-height budget from the top of the host board to the underside of the PMC module. If your enclosure has a fixed card cage, the 14mm stack keeps the module lower; the 15mm option adds clearance for taller components on the mezzanine card. Both heights use the same footprint, so you can swap between them by changing the mating header height alone.","metaTitle":"TE 5120531-1 Free Height Receptacle, 64 Pos, 1.00mm Pitch","metaDescription":"TE 5120531-1 Free Height receptacle, 64 positions, 0.039\" (1.00mm) pitch, SMT, gold 30.0µin contacts.
