The DSC1033CI1-044.0000: It operates from a 3.3 V supply and draws a maximum of 4 mA typical, making it suitable for power-sensitive designs where a quartz oscillator would consume more current.
The 3.20 mm x 2.50 mm no-lead package with a 0.90 mm seated height fits compact PCB layouts where height is constrained.

Both share the same base product number DSC1033 and the same 44 MHz frequency, CMOS output, and 3.3 V supply. The CI1 and CI2 suffix variants may differ in frequency stability or temperature range — verify the specific stability (±50 ppm here) and operating range against your design requirements before substituting.
Yes, it includes a standby (power-down) function that reduces supply current to 1 µA maximum when the clock output is disabled.
