The DSC6001JI1A-013.5212T is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a fixed 13.5212 MHz CMOS output. AEC-Q100 qualification confirms it meets automotive-grade reliability testing: temperature cycling, ESD, and extended life stress. The -40°C to +85°C operating range covers cabin and most engine-bay ambient conditions, though the full AEC-Q100 Grade 1 band extends to +125°C — this part stays within the 85°C ceiling.
Obsolete status and sourcing path
Microchip lists the DSC6001JI1A-013.5212T as Obsolete. Because the part is discontinued, a board-level respin may be required if volume production continues. The DSC60XX family includes many active frequencies and grades; a cross-reference search against the same 2.50mm x 2.00mm 4-SMD no-lead footprint and 1.71V–3.63V supply range is the first step in identifying a drop-in candidate.
Supply voltage tolerance and stability margin
The 1.71V–3.63V supply range covers 1.8V, 2.5V, and 3.3V rails without an external LDO — the internal regulator handles the translation, so the same part works across multi-voltage boards. The ±50 ppm frequency stability is the total variation over temperature, supply, and aging; for a 13.5212 MHz clock, that is a worst-case jitter budget of about 677 Hz — tight enough for a CAN transceiver or MCU main clock, but not for a high-speed SerDes reference. The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.89mm, fitting dense PCB layouts where board area is constrained.
