Supply voltage spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator. The 1.3 mA typical supply current at 25 MHz is low enough for battery-powered modules — a sensor node clocking a Cortex-M0 at 25 MHz won't waste the power budget on the oscillator. That's tight enough for a 100BASE-TX Ethernet PHY or a USB full-speed controller, but not for a GPS disciplined oscillator — the ppm budget there is usually ±2.5 ppm or better.
For existing BOM lines, the last-time-buy window has closed; remaining stock is limited to independent surplus channels. No pin-compatible successor is listed in the DSC60XX series. A functional replacement would need the same 4-SMD no-lead footprint, 25 MHz frequency, CMOS output, and enable/disable function — but the MEMS die and package may differ. Confirm the replacement's frequency stability and supply voltage range against the original spec before committing the board.
Automotive-grade qualification and package note
The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. No exposed pad; decoupling with a 100 nF cap near the supply pin is sufficient.
