Microchip DSC1001CL2-040.0000T is a 40 MHz MEMS-based oscillator with CMOS output, ±25 ppm frequency stability, and a wide supply range of 1.8V to 3.3V.
The 4-SMD, no lead footprint (3.20 mm x 2.50 mm) matches the industry-standard 3225 crystal oscillator land pattern — confirm the enable/disable pin mapping against the existing quartz part before committing.
The DSC1001 is a MEMS-based XO with CMOS output, not a bare crystal — it requires a power supply (1.8V to 3.3V) and is a drop-in replacement only if the original design used a 40 MHz oscillator module in the same 3225 footprint with CMOS output. The MEMS start-up is faster than a quartz oscillator and the frequency stability (±25 ppm) is comparable to standard quartz XOs.
