Urgent Opinion on alternative RAM for my laptop

Hello all,

I wanted to ask a simple question which has become a headache for me.

I am using Acer Aspire A715-41G Gaming laptop which has Samsung DDR4-2666 Mhz 1.2v 8GB Ram in one of the slot. I want to upgrade the RAM on the second slot. I searched for the same model RAM using CPU-Z tool. But the RAM stick is been discontinued by Samsung and I am unable to find the same stick online (Legit one). I wanted to ask if this different RAM stick is compatible with the other RAM stick. Please do let me know. Thanks in advance!

Both the RAM Sticks have same DDR4-2666Mhz and volts, but a different model number. Some reviews says its fake, but I am open to suggestions from the community. Hoping to see a reply soon.
