My guess is yes. I see references to DW-D26A, DWD-26A, and DWD26A, and I cannot believe they are three different Sony products.
I don't have the time to do extensive burn quality testing these days, but I can tell you the drive has handled everything I've thrown at it so far -- no coasters, no compatibility problems.
Mainly, I was happy that I was able to cross-flash this unit to its LiteOn equivalent because support (firmware upgrades, etc.) for Sony OEM drives is virtually non-existent.
