HPE SAS expander cards for G8 G9 G10 any difference?

[PDP-Fan]

I'm testing HPE SAS expander cards right now and I found, there are two different part numbers for the (seemingly) same thing. So I wonder what the diffrerence might be...

761879-001 SAS Expander Card PCI for Gen8 and Gen9
876907-001 SAS Expander Card PCI for Gen9 and Gen10

I tested the 761879-001 card in a Gen10 and a Gen8 server and it worked fine in both of them.  Both cards have 8 input ports and 28 output ports, 12Gb/s SAS and 6GB/s SATA. Searching for pictures on Google, I found that both cards look exactly the same. I wonder if there is any difference at all, or if the two cards are interchangeable?
I can see that the option number are different too, but I guess that's because they come with different cable sets for different server models. But how about the card itself?

Hello,

As mentioned by you, both appear to the same. May be it is about the availability of the mentioned card.
