Product details

The DSC1033BI1-035.3280 is a fixed-frequency MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 35.328 MHz CMOS output at 3.3V supply. The MEMS resonator replaces a quartz crystal, offering inherent shock and vibration tolerance over a crystal oscillator in the same 5.0 mm × 3.2 mm 4-SMD no-lead footprint.

Standby function and current profile

Active draw is 3 mA typ, keeping the thermal contribution low in a sealed enclosure.

Microchip lists the DSC1033BI1-035.3280 as Obsolete. No pin-compatible successor is recorded under the same order code; a board-level redesign to a current Microchip MEMS oscillator family is the migration path.

Frequently asked questions

Is DSC1033BI1-035.3280 obsolete?

Buyers need to know if the part is end-of-life to avoid production gaps or find a last-time buy opportunity.

What is the replacement for DSC1033BI1-035.3280?

Sourcing and maintenance teams require an exact or functional drop-in replacement to keep designs and repairs viable.

Where can I buy DSC1033BI1-035.3280 in stock?

Distributor stock availability directly impacts procurement timelines, especially for obsolete parts with limited inventory.

What are the specifications of DSC1033BI1-035.3280?

Design engineers need to verify frequency, voltage, stability, and package fit before selecting or substituting the part.

What is the lead time for DSC1033BI1-035.3280?

Lead time affects BOM readiness and production scheduling, critical when the part is near end-of-life.

Does DSC1033BI1-035.3280 have a cross-reference to a newer Microchip part?

Brokers and engineers need a verified cross to an active series (e.g., DSC1033 series successors) for long-term supply.
