Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the footprint is compatible with many standard quartz XO layouts of the same dimensions, easing second-sourcing. Surface-mount only — no through-hole variant.
This is a current-design-in part suitable for new projects; no successor or replacement has been issued.
No — the supply voltage is specified as 3.3V only. Operating at 2.5V is outside the datasheet operating range and the oscillator may not start or maintain frequency stability.
When the Standby (Power Down) pin is asserted, supply current drops to 1 µA maximum — this is the current consumed by the internal power-down circuitry; the output is high-impedance.
Within the same DSC1033 family, any other frequency variant with the same package (4-SMD, 2.5x2.0mm), supply voltage (3.3V), and output type (CMOS) is pin-compatible. Outside the family, many standard quartz XOs in the same 2.5x2.0mm footprint share the pinout, but confirm the Standby function polarity — some parts use a different logic level for enable/disable.
