288-Pin DDR4 DIMM Socket – Board Fit and Retention
The 2308107-9: The 288 contacts match the JEDEC-defined DDR4 module edge connector, so the BOM position count is non-negotiable – a 288-pin socket is the only fit for a standard DDR4 DIMM. The integrated latches snap over the DIMM module ears to hold it against vibration and thermal cycling – a common failure point in unlatched sockets where the module works loose over time. For a DIMM socket that may see dozens of memory upgrades over its service life, 15µin gold provides a reliable mating interface for several hundred insertion cycles without exposing the base copper to corrosion from humidity or flux residues.
RoHS compliance is documented, covering the lead-free solder finish and halogen-free materials required for EU and many Asian markets. No additional compliance documentation is needed for standard commercial equipment builds.
The socket accepts standard DDR4 DIMM modules with a 288-pin edge connector. The through-hole mounting style requires a PCB with plated through-holes matching the socket pin layout – the board lock features seat into corresponding holes on the board, not just the signal pins. The package is tray, which is the typical carrier for DIMM sockets in automated assembly. Tray packaging keeps the connector bodies from tangling and protects the contacts during shipping and pick-and-place handling.
