What this 260-position DDR4 SODIMM socket fits
The 2309407-1 is a 260-position DDR4 SODIMM connector from TE's AdvancedMC series — the position count matches the JEDEC DDR4 standard, so it fits standard DDR4 memory modules. The connector style is SODIMM, not a generic header, meaning the slot is keyed for notebook or embedded memory cards.
Mounting orientation and board clearance
This connector mounts surface-mount at a 25° angle — the module inserts at that angle and then locks down parallel to the board. The 25° angle sets the z-height budget during insertion; the board layout must clear the module's swing arc. The normal, standard-top mounting feature means the connector sits on the component side, not inverted. Board guide and latches are included — the guide aligns the module during insertion, and the latches hold it in place against vibration. No secondary lock is needed for a memory slot, but the latches are the only retention mechanism; a high-shock environment may need additional clamping.
CT works for prototype or low-volume runs.
Cross-shop: 2309407-1 vs 2309410-3
The closest functional alternative is the 2309410-3 — same 260-position DDR4 SODIMM form factor, same 25° insertion angle, same board guide and latches. The differences: the 2309410-3 uses reverse mounting (connector on the opposite board side) and carries 10.0µin gold contact finish instead of flash. If your board layout requires the connector on the reverse side or you need the extra mating cycle margin from thicker gold, the 2309410-3 is the direct swap.
