What is the difference between the part in the Subject line and the one with the K added?

I could not see this immediately. 

What is the longevity of the K part?

HI Alice

Thanks for the reply. I wonder if you could find more about the K suffix. Maybe it is an internal process change in the manufacturing of the part?

I think your answer is sufficiently substantive though.

I only can find the information as below:

About deeply information about packing, you can ask distributor, they know this more detail.

I can confirm the function feature are the same, and the longevity is the same:
