Housed in a 4-SMD, No Lead Exposed Pad package measuring 0.276" x 0.197" (7.00mm x 5.00mm) with a seated height of 0.035" (0.90mm). Typical supply current is 3 mA — the MEMS resonator draws less than a quartz equivalent at this frequency, which matters for power-constrained designs.
No pin-compatible successor is listed in the lifecycle record. A replacement will require a board spin — confirm the package footprint, supply voltage, and output type before migrating. The DSC1033 series uses a 4-SMD no-lead exposed-pad layout; any MEMS or quartz XO in the same 7.0 x 5.0 mm footprint with CMOS output and 3.3V supply is a candidate, but verify the standby function pinout.
