• Piezoelectric transducer technology provides reliable acoustic output
• Compact cylindrical form factor suitable for space-constrained enclosures

Applications

• General purpose alarm systems
• Appliance status indicators
• Portable electronic device alerts

Procurement Notes

Verify the specific suffix codes on the component body against official Mallory Sonalert documentation to confirm electrical characteristics and mounting configuration. Ensure that the operating voltage matches the datasheet specifications to prevent damage or reduced performance. Cross-reference part numbers with authorized distributors to avoid counterfeit products.

Selection Notes

Select this component based on its fixed 1600 Hz frequency and 85 dB output level. Consider the physical dimensions and through-hole mounting requirements during PCB layout. Evaluate whether the integrated oscillator meets the system's timing needs compared to externally driven buzzers.

Part Context

This model belongs to the SC series of piezoelectric buzzers designed for cost-effective audio signaling. The series offers various frequencies and sound levels to suit different application requirements while maintaining a consistent mechanical footprint for easy integration into existing designs.

Replacement Considerations

Consult official substitution guides for equivalent models with matching frequency and voltage ratings. Verify pinout compatibility before replacing the original component to ensure proper electrical connection.
