DDR SDRAM SODIMM Socket—Board Fit and Memory Compatibility
The 1717254-1: This is a 200-position SODIMM socket designed for DDR SDRAM memory modules, with a right-angle surface-mount orientation that places the module parallel to the PCB. The gold flash on the contacts provides the mating cycle life expected in a memory-upgrade or field-service application—adequate for the typical 50–100 insertion cycles a SODIMM sees over its service life. The memory type is listed as DDR SDRAM, which covers the DDR1 through DDR3 generations. It is not explicitly listed as DDR4 compatible, so confirm the keying and voltage requirements of your specific module before committing the BOM line.
Mounting and Retention—Board Guide and Latches
The connector includes a board guide and latches. The board guide aligns the SODIMM module during insertion, preventing pin damage. The latches lock the module in place, providing vibration resistance—useful in mobile or industrial equipment where the memory module sees shock or movement. The standard-top mounting feature means the latches and alignment features are on the top side of the connector, consistent with typical SODIMM layouts. The right-angle orientation keeps the module low-profile against the board.
ROHS3 compliant, which covers the full RoHS exemption list including lead in solder joints. No additional compliance documentation is required for EU market use. Available in Tape & Reel (TR) for automated pick-and-place or Cut Tape (CT) for prototype and low-volume builds.
