Product details

The DSC1033DC1-012.0000T: The MEMS base resonator gives this oscillator better shock and vibration tolerance than a quartz equivalent — relevant for equipment that sees mechanical stress during transport or operation, such as outdoor telecom cabinets or factory-floor controllers.

Standby function and power-down current

The Standby (Power Down) function disables the output and drops supply current to 1 µA maximum — useful for battery-powered systems that need to preserve charge during idle periods without removing the oscillator from the board.

Microchip lists the DSC1033DC1-012.0000T as Obsolete. No official successor or pin-compatible replacement is recorded from the original manufacturer. Available through independent surplus channels in lot-specific quantities.

Frequently asked questions

How can I order DSC1033DC1-012.0000T or check availability?

This part is obsolete and sourced through independent distribution. Submit an RFQ with your target quantity; we confirm availability and current pricing at quote time. No stock-holding claim is made.

What is the replacement for DSC1033DC1-012.0000T?

No official replacement or pin-compatible successor is recorded from Microchip. A functionally equivalent MEMS oscillator from the same or another series would require verifying the package (4-SMD, 2.5mm x 2.0mm), supply voltage (3V–3.6V), output type (CMOS), and frequency stability (±50 ppm) against the new part's datasheet.
