TE Connectivity Free Height Series Straight Surface Mount PCB Socket, 40-Contact, 2-Row, 0.031mm Pitch, Solder

0.8mm Free Height (FH) board to board or mezzanine SMT receptacle connectors for use in parallel board stacking applications. These Free Height (FH) mezzanine connectors have a high density subminiature packaging with a .031mm centreline spacing making it possible to save more than 50% space on the PCB compared to 1.27mm centreline connectors. The contacts of these 0.8mm Free Height (FH) connectors have a bellows type spring design that is resistant to scooping and stubbing when the connector is mated and unmated and offers a reliable electrical connection. These 0.8mm Free Height (FH) receptacles feature polarization to ensure accurate mating and have PCB postioning bosses for accurate placement on the PCB. A range of board to board stacking heights from 5 to 16mm can be achieved by mating these 0.8mm FH receptacles with different board mount plugs.
Typical applications for these 0.8mm Free Height (FH) board to board receptacle connectors include notebook PCs, pen pads, mobile phones and other electronic equipment that requires miniature connector packaging.
Part numbers X-5177983-X and 5177985-X are 5mm FH vertical receptacles for 5, 6, 7 and 8mm stacking heights
Part numbers X-5179009-X and X-5179180-X are 9mm FH vertical receptacles for 9, 10, 11 and 12mm stacking heights
Part numbers X-5179010-X and X-5084616-X are 13mm FH vertical receptacles for 13, 14, 15 and 16mm stacking heights

Tyco Electronics 0.8mm FH surface-mount connectors are designed for parallel board stacking applications using subminiature connectors to meet today’s electronic industry requirements for high density packaging. It is possible to save more than 50% of the required board space when com- pared to conventional 1.27 [.050] centerline connectors. 0.8mm FH connectors are ideally suited for application downsizing, such as note- book PCs, pen pads, cellular telephones and other electronic equipment requiring miniature connec- tor packaging. Vertical board-mount plugs and receptacles are avail- able. By mating combinations of plug and receptacle housing heights, board-to- board stacking heights from 5 [.197] to 16 [.630] (in 1 [.039] increments) can be achieved. The receptacles are preloaded with the Tyco Electronics unique bellows-type spring contacts for reliable electrical connection with the plugs. In addition, right angle plugs are available which mate to standard receptacles.
