upgrade memory

Hi

I I have Dell Inspiron 15R 5520 it has come with a memory Hynix 4GB As shown in the picture

f0458f69-c6ba-4ba6-aa5b-d6d02ee231b8.jfif

And I want to add a new 4GB memory to be 8GB

I searched in amazon for the same type

And I found two, but they don't match in the last two numbers. I've marked the part in red that doesn't match

My questions

What does this last part of the numbers mean?

And if I buy one, it will be identical to the old memory and will work without problems?

There should be no problem using the RAM. 1228, These are just time codes when it was manufactured. 12 should be week day or number or month & 28 should be the date or week number when it was manufactured.

Almost all details r mentioned by U2CAMEB4ME. That PBC 203V means it will cary the power supply upto that voltage. Basically u need to check the RAM Type & memory which ur laptop supports. as it similarly works as motherboard & has voltage, clock speed, data handling & more as mentioned by U2CAMEB4ME. @U2CAMEB4ME - please help understanding if wrong.
