The 6-SMD no-lead package (2.50 mm x 2.00 mm x 0.90 mm) is a standard MEMS oscillator footprint, compatible with reflow soldering and common pick-and-place equipment. Store the reels in dry conditions per MSL handling guidelines.
This is tight enough for most microcontroller and interface timing, but not for precision RF or high-speed serial links that require sub-10 ppm stability.
It is a functional replacement in terms of frequency and CMOS output, but the MEMS resonator behaves differently under vibration and has a different startup profile. Verify the Enable/Disable pin logic and supply voltage range (2.25 V to 3.6 V) against your existing quartz oscillator's specifications before substituting.
