288-Pin DDR5 DIMM Socket – Board Fit and Memory Generation
The 2-2355627-1: This is a 288-position DDR5 SDRAM DIMM socket from TE Connectivity, designed for standard top-mount surface-mount assembly. The 288 circuit count matches the JEDEC DDR5 DIMM specification — the same pinout used across all DDR5 memory modules, so compatibility is with the generation, not a specific module brand or speed grade. The integrated latches retain the memory module against vibration in rack-mount and industrial environments. The 0.050" (1.27 mm) card thickness acceptance matches the standard DDR5 module PCB thickness — no mechanical fit issue with any JEDEC-compliant DDR5 DIMM.
DDR4 SODIMM vs DDR5 DIMM – Why the Peer Is Not a Drop-In
Card thickness differs: 0.050" for this DDR5 DIMM vs 0.047" for the DDR4 SODIMM — the 0.003" gap means a DDR5 module will not seat reliably in the DDR4 socket, and vice versa.
