DDR3 DIMM Socket — 240 Positions, SMT, Board Lock
The 2040727-1: It uses a surface-mount termination with a standard top-mounting orientation — the module inserts parallel to the board, and the board lock and latches hold it in place against vibration and handling during assembly.
For a DDR3 DIMM socket replacement, a board spin is typically required: the 240-position DDR3 form factor is standardised by JEDEC, but the exact footprint, keying, and mounting features vary by supplier. Cross-reference the board layout against current TE or competitor DDR3 sockets before committing.
The 2040727-1 accepts a standard DDR3 SO-DIMM or UDIMM module with 0.050" (1.27 mm) card thickness. Surface-mount termination with gold flash contacts — the contact resistance is stable for the rated mating cycles of a DIMM socket (typically 25–50 cycles). In a field-service scenario where the memory module is swapped quarterly, the gold flash provides adequate corrosion protection for the service life of the equipment.
