The DSC6003CI2A-012.0000T is a 12 MHz MEMS-based XO (standard type) producing a CMOS output from a 1.71V to 3.63V supply rail, housed in a 3.20mm x 2.50mm 4-SMD no-lead package. Its ±25 ppm frequency stability covers the majority of automotive and industrial timing budgets without requiring an external crystal.
Lifecycle Reality: Obsolete, Sourced via Independent Channels
No official successor or drop-in replacement part number has been published by the manufacturer. For existing BOM lines, availability is limited to surplus and independent-distribution stock. Quantities are lot-specific and confirmed only at the time of RFQ; there is no guaranteed forward supply.
Operating Range and Supply Voltage Flexibility
The wide 1.71V–3.63V supply range lets this oscillator work on 1.8V, 2.5V, or 3.3V rails without a separate level translator — a single part number covers multiple voltage domains in a mixed-signal design. Industrial temperature range -40°C to +85°C covers most automotive cabin and many under-hood locations, though a true under-hood application near the engine block would need the full -40°C to +125°C grade that some DSC60XX variants offer.
