But the headline here is lifecycle: this part is marked obsolete. That means it's no longer supported for new designs, and production allocations are gone. ## Package and temperature fit for industrial boards Housed in a 4-SMD No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, this oscillator fits tight PCB real estate — common in compact IoT gateways, PLC I/O modules, or sensor interfaces. ## Sourcing an obsolete oscillator — what to expect Microchip lists the DSC1033DI1-040.0000T as obsolete. For buyers filling a BOM line, we source this part through independent distribution — the availability and price are confirmed per RFQ, and quantities are lot-specific. If you're designing a new board, a current-production MEMS oscillator in the same 2.5x2.0 mm footprint and 3.3V CMOS logic would be the cleaner path; we can help identify options at quote time.","metaTitle":"DSC1033DI1-040.0000T MEMS XO 40 MHz 3.3V CMOS Obsolete –","metaDescription":"DSC1033DI1-040.0000T: Microchip PureSilicon™ MEMS XO, 40 MHz, CMOS output, 3.3V, ±50ppm, -40°C~85°C.
