Its standby (power-down) function drops supply current to 1µA max, making it suitable for battery-operated or intermittently powered designs where the oscillator must sleep between active periods. The 3.3V supply rail and 4-SMD, No Lead Exposed Pad package (7.00mm x 5.00mm footprint, 0.90mm seated height) fit standard oscillator land patterns used in networking, industrial control, and embedded systems.
Microchip has not published an official pin-compatible successor for this part. A current-production MEMS or quartz oscillator with the same 25 MHz frequency, 3.3V supply, CMOS output, and 4-SMD footprint would be the functional replacement, but a board spin may be needed to match the standby function and ±25ppm stability.
