It is the board-side half that accepts the mating plug — typically the 1-120532-2 or similar center-strip-contact plug — to create a mezzanine interconnect between a carrier board and a PMC module. The 0.039\" (1.00mm) pitch in a dual-row layout packs 64 circuits into a compact SMT footprint, with the outer shroud contacts providing mechanical alignment and protection during board stacking. The board height of 0.211\" (5.35mm) and support for mated stacking heights of 8mm, 9mm, and 10mm give the board layout engineer three board-to-board gap options — the actual stack height is set by the plug height selected, not the receptacle alone. The board guide feature assists alignment during blind mating in a card cage — without it, the fine 1.00mm pitch contacts risk stubbing during insertion. Surface-mount termination suits reflow assembly on the carrier board, but the narrow pitch demands careful solder-paste stencil design to avoid bridging between adjacent pads. ## Stack height selection — picking the right board-to-board gap The 5146893-1 receptacle itself has a fixed board height of 0.211\" (5.35mm). The mated stack height — the total gap between the two PCBs — depends on which plug height you pair it with. The receptacle supports three mated stacking heights: 8mm, 9mm, and 10mm. This means the same board-side footprint can accommodate different PMC module thicknesses or component keep-out zones on the underside of the mezzanine card. Confirm the plug height before committing the BOM — the receptacle alone does not determine the stack. ## Mating with the PMC plug — what fits this receptacle This receptacle mates with the Free Height (FH) IEEE 1386 plug connector — the male half with center strip contacts. The most common mate is the TE 1-120532-2, a 84-position plug, though the 64-position receptacle only uses 64 of those positions; the extra contacts on the plug remain unconnected. The outer shroud on the receptacle aligns with the plug's center strip during stacking, and the board guide features on both halves prevent misalignment during insertion. The mated pair is not keyed for polarization — the connector relies on the PMC card edge and card guide rails for correct orientation.","metaTitle":"TE Connectivity 5146893-1 Free Height FH Receptacle, 64 Pos","metaDescription":"TE Connectivity 5146893-1 Free Height (FH) IEEE 1386 receptacle, 64 positions, 0.039\" (1.00mm) pitch, SMT, gold contacts.
