Its 1.71V to 3.63V supply range lets a single BOM line serve 1.8V, 2.5V, and 3.3V clock domains without a level shifter.
No official successor part number is recorded from Microchip. A pin-compatible functional equivalent from the same DSC60XX family may exist; verify the exact frequency, supply range, and enable logic against your BOM position. A board spin is required if no drop-in replacement is found.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — the 0.098" x 0.079" footprint matches standard MEMS oscillator land patterns. Frequency stability is ±50 ppm over the -40°C to +85°C industrial/automotive temperature range, with a typical supply current of 1.3 mA max.
