Maximum active current is 8.7 mA, so the thermal footprint in a 2.5 mm x 2.0 mm 4-SMD package is negligible.
The DSC1001DE1-148.5000 is available for design-in and production. No pin-compatible alternative is listed, but the DSC1001 series shares the same footprint across frequencies — a frequency change within the family keeps the same PCB layout.
Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade qualification stress tests — temperature cycling, ESD, latch-up. This makes it suitable for designs that require documented reliability, even though the operating temperature range is -20°C to 70°C.
Yes, it is a direct functional replacement for a standard quartz XO at 148.5 MHz with CMOS output. The MEMS resonator offers better shock resistance and typically faster startup than quartz. Confirm the supply voltage (1.8V-3.3V) and package footprint (4-SMD, 2.5mm x 2.0mm) match your existing oscillator.
When the standby (power-down) function is enabled, maximum supply current is 15 µA. Active current is 8.7 mA max.
