I have a pair of DDR3 SODIMM RAM modules in my laptop, and I want to replace the 2GB for a 4GB that is compatible. So far I haven't been able to find an exact match but I found a very similar with a PC3L label instead of PC3. Can they work together?
My DDR3 SODIMM RAM:
Memory module in question:
Installed RAM: 4GB DDR3 2Rx8 PC3 12800S 11 10 F2
Matching RAM: 4GB DDR3 2Rx8 PC3L 12800S 11 10 F3
Laptop: Toshiba Satellite L645D-S4036

What you are referring to is related to DDR3 memory standardization.
Most, if not all PC3L modules can support 1.50V operation, so there shouldn't be any issues in your case
Edit. I've just checked in the Samsung catalogue, and I can confirm now that your Samsung M471B5273CH0 PC3L is dual voltage module. Enjoy :)
