From what I can see from pictures on various retailer web-sites, the K-AC167 is effectively the K-AC168 without the 'dummy' battery (and at a significantly higher price!). The suffix letter, "E", "U" etc. seems to refer to regional variations for the complete "kit", specifically the wall-plug on the mains lead, the other end of which has the generic "figure-8" connector to the adaptor itself.
With this in mind, I'd suggest that either unit would be satisfactory for any Pentax DSLR using an 8.3v DC supply via the little rectangular connector.

*ist cameras have a different requirement. At what point the change-over occurred I don't know, possibly when cameras stopped using AA-cells internally and I know the K-01 is different again, requiring an Li90-size 'dummy' in conjunction with the 8.3v adaptor.
