Your link is to the datasheet for the Nichia NVSW219CT (Nichia 219C) which is normally fitted to a standard 3535 XP board (even though it has a footprint that is marginally smaller), so you’re after something with a standard 3535 XP footprint.
LEDs with this footprint include Cree XP LEDs (XP-Ex, XP-Gx, XP-Lx), the Luminous SST-20, the Luxeon V2 and the Samsung LH351D. There’ll be others i don’t know about.

Samsung do a 5000K HCRI LH531D but i don’t know if they do a 5500K version so i don’t know any LEDs that match your criteria, but at least you know you’re looking for something with a standard 3535 XP footprint.
