200-Position SODIMM Socket for DDR Memory Modules
The 1473006-1 is a 200-position SODIMM socket from TE Connectivity, designed for DDR SDRAM memory modules. The 200-position layout matches the standard DDR2 and DDR3 SODIMM interface, making it a direct BOM fit for memory upgrades in laptops, embedded systems, and industrial computers. The right-angle orientation with a 25° insertion angle and reverse mounting feature allows the memory module to sit parallel to the PCB at a low profile, saving vertical space inside tight enclosures.
Mated Height and Board Clearance
The mated height of 0.205" (5.20 mm) is the critical dimension for slot clearance under a keyboard, top cover, or heatsink. This height is typical for standard SODIMM sockets and ensures compatibility with most DDR2/DDR3 modules.
Contacts are finished with gold flash over nickel. Gold flash provides adequate corrosion resistance for the typical 100–200 mating cycles expected in a SODIMM socket, without the cost of thicker gold plating. For applications requiring significantly more cycles, consider a connector with 15 µin or thicker gold.
Mounting and Retention Features
The socket includes board guides and latches to align and secure the memory module during insertion and under vibration.
