16GB DDR5 4800 SODIMM for Latitude 5431 5531

This 16GB DDR5 4800 CL40 SODIMM is built for Dell Latitude 5431 and 5531 laptops. It runs at 1.1V with a 1Rx8 layout and fits the 262-pin slot. The module is JEDEC-standard and RoHS compliant.

Suits owners of Latitude 5431 5531 needing

Buyers whose laptop uses a different pin count or voltage cannot use this module. Systems requiring ECC or registered memory should look elsewhere. The part replaces Dell numbers AB949334 AC258275 SNPCYXXPC/16G SNPVNY72C/16G.

262-pin DDR5 4800 1.1V non-ECC SODIMM

The 262-pin DDR5 form factor at 1.1V is the specification that decides fit. If the service manual for your Latitude 5431 or 5531 calls for this exact pin count and voltage, the module will install. Otherwise it will not seat or function.
