DDR5 DIMM Socket — 288 Positions, Vertical SMT
The 8-2355626-1 is a TE Connectivity DDR5 SDRAM DIMM socket with 288 positions in a vertical, standard-top mounting orientation. It uses surface-mount termination and carries a 30.0µin gold contact finish for reliable signal integrity across repeated memory module insertions. This socket is designed for DDR5 SDRAM modules, supporting the higher data rates and lower operating voltages of the latest memory generation. The 288-position layout matches the JEDEC standard for DDR5 DIMMs, ensuring compatibility with DDR5-4800 and faster modules.
Board Lock and Latch Retention
The board lock feature provides mechanical retention during the SMT reflow process — the metal tabs solder to the PCB, holding the socket in place before the DIMM is inserted. Once mated, the latches engage the module's side notches to prevent accidental disconnection. This dual retention system is typical for high-reliability memory interfaces in servers, workstations, and industrial computing where the DIMM must stay seated under shock and vibration.
