It uses a right-angle surface-mount termination and sits at a height of 0.220\" (5.60 mm) above the board. The gold-plated contacts with 10.0µin thickness provide reliable signal integrity for repeated module insertions — the gold flash is adequate for the typical 100-200 mating cycles in a laptop or embedded system, not for a high-cycle production test socket. The housing includes integrated board guides and latches — the guides align the module during insertion, and the latches hold it against vibration and accidental dislodging. This is a practical feature for field-service where a loose SODIMM is a common intermittent-failure cause. ## Board layout and orientation considerations The 0.220\" (5.60 mm) height sets the z-height budget above the PCB; the card thickness spec of 0.050\" (1.27 mm) defines the module edge thickness the contacts accept. The SMT footprint requires a reflow profile compatible with the gold-plated contacts and the natural (uncolored) housing. The board guide and latch features add mechanical retention beyond the solder joints — important for boards subject to shock or vibration during shipping or field use. ## Memory compatibility and application fit The connector is specified for SDRAM memory type — this is a standard SODIMM socket for SDRAM modules, not a DDR-specific variant. It will physically accept DDR1, DDR2, and DDR3 modules that follow the 144-pin SODIMM form factor, but the electrical compatibility depends on the module's edge connector keying and signal assignment. For DDR4 or higher-density modules, the 260-position 2309410-3 is the correct choice.","metaTitle":"3-390112-1 TE Connectivity SODIMM Socket 144-Pos R/A SMD","metaDescription":"3-390112-1 TE Connectivity AMP Connectors SODIMM socket, 144 positions, right-angle SMT, gold-plated contacts, active production.
