Outer shroud contacts guide the mating plug and protect the signal pins from damage during assembly. ## 3 mm Stack Height — What It Means for the Board Layout The 3mm mated stacking height is the dimension that decides the clearance between the two PCBs. With the receptacle sitting 2.40mm above its own board, the mating plug (from the same Fine Stack series) occupies the remaining 0.60mm of the stack. This is a fixed-height mezzanine pair — no adjustment, no standoffs. The 0.80mm pitch limits trace escape from the inner rows — expect to use micro-vias or blind vias if routing all 12 signals out on a single layer. Two rows of contacts, staggered, give 6 positions per row. ## Tin Contacts — When to Use and When to Avoid","metaTitle":"TE 1-179397-2 Fine Stack Receptacle, 12 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity 1-179397-2 Fine Stack (FS) receptacle, 12 positions, 0.80mm pitch, 3mm mated stack height.
