Product details

The DSC1033CI2-025.0000T is a 25 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output from a 3.3V rail with ±25ppm frequency stability. The MEMS base resonator replaces a quartz crystal, offering better shock and vibration tolerance in a 3.20mm x 2.50mm 4-SMD no-lead package.

Power budget and standby capability

Active current draw is 3 mA typical at 25 MHz, making it a low-power choice for battery-backed real-time clocks or always-on sensor interfaces.

For new designs, consider a current-production MEMS oscillator from Microchip's DSC11xx or DSC6xxx families with similar package and electrical ratings; confirm pin compatibility against the 4-SMD footprint.

Frequently asked questions

Is DSC1033CI2-025.0000T obsolete, and what is the replacement?

Yes, Microchip has marked the DSC1033CI2-025.0000T as Obsolete. No direct replacement is listed by the manufacturer. For new designs, evaluate a current-production MEMS oscillator from Microchip's DSC11xx or DSC6xxx families with the same 3.3V supply, CMOS output, and 4-SMD footprint. For existing BOMs, surplus lots are available — confirm the date-code spread and packaging condition at RFQ.
