Product details

The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, and the supply voltage spans 2.25V to 3.6V, covering common 2.5V, 3.0V, and 3.3V rails without a separate regulator.

Package, footprint, and enable/disable function

Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1121BI2-148.5000T uses the same 6-pin land pattern as many standard quartz oscillators — the pinout is compatible, so it can drop into an existing board layout without a respin.

Available in Tape & Reel (TR) packaging.

Frequently asked questions

What are the complete specifications of DSC1121BI2-148.5000T?

Engineers need datasheet info to validate fit and compatibility.

Is the DSC1121BI2-148.5000T pinout compatible with standard 6-pin oscillators?

Pinout compatibility is critical for drop-in replacement without PCB redesign.

Where can I buy DSC1121BI2-148.5000T and what is the current stock?

Buyers need to source the part quickly for production or prototype builds.

What is the best price for DSC1121BI2-148.5000T in tape and reel quantities?

Pricing affects BOM cost and purchasing decisions.

Is DSC1121BI2-148.5000T a suitable direct replacement for a standard quartz oscillator?

Engineers often switch from quartz to MEMS for reliability and size, need cross-compatibility.

What are the EOL or obsolescence plans for DSC1121BI2-148.5000T?

Brokers and long-term buyers need lifecycle assurance to avoid redesigns.
