200-Position Reverse SMT SODIMM Socket for DDR2
The 10033854-052FSLF: This is a 200-position reverse surface-mount SODIMM socket from Amphenol ICC (FCI), designed for DDR2 SDRAM memory modules. The 30° angle insertion allows the module to sit at a low profile relative to the board — common in laptops and embedded systems where z-height is tight. The socket accepts DDR2 modules with a card thickness of 0.039" (1.00 mm) — the standard for that memory generation. Board guides on the socket body align the module during insertion, and the latches lock it in place once seated. The black housing is a visual cue that this is the DDR2 variant in the 10033854 series.
The contacts are finished with gold flash — the thinnest gold plating grade available. For a DDR2 SODIMM socket, this is the standard choice: the module is inserted once during manufacturing and rarely cycled again in the field. Gold flash provides adequate corrosion resistance and contact reliability for the expected 10–50 mating cycles over the product's life. If your application requires frequent module swaps — say, a test fixture or a field-upgradable memory slot — you would want a socket with thicker gold (15–30 µinch) to avoid contact fretting and resistance drift.
