Product details

The DSC1033DI1-012.0000T is a 12 MHz MEMS-based oscillator from Microchip's PureSilicon™ DSC1033 series, delivering a CMOS output at 3.3 V with ±50 ppm frequency stability. The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts alongside other SMD passives.

Microchip lists the DSC1033DI1-012.0000T as Obsolete. A board-level redesign may be required to migrate to a current-production oscillator.

Active supply current is 3 mA typ, a low figure for a 12 MHz output, keeping the thermal contribution minimal in the small 4-SMD package.

Frequently asked questions

What is the replacement for DSC1033DI1-012.0000T?

A board-level redesign to a current-production MEMS or quartz oscillator is required.

What are the exact specifications of DSC1033DI1-012.0000T?

The package is 4-SMD no-lead, 2.50 mm × 2.00 mm, with a standby function drawing 1 µA max when disabled.
