Procurement Notes
Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with your circuit design. Confirm that the surface mount footprint matches your PCB layout constraints. Check for any recent product change notifications regarding material composition or manufacturing location updates before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, internally driven solution is required for space-constrained designs. Ensure the operating voltage aligns with the 4-7VDC specification. Consider the 30mA current consumption during power budget calculations. Verify that the 2.7kHz frequency meets acoustic requirements for the intended application environment.
Part Context
This part belongs to the Mallory Sonalert family of audio indicators. It represents a transition from through-hole to surface mount technologies for magnetic buzzers. The series is designed for high-volume manufacturing integration. It serves as a direct replacement for older through-hole equivalents in modern PCB designs requiring reduced profile height.
Replacement Considerations
Cross-reference with other Mallory Sonalert surface mount magnetic buzzers. Verify pinout and footprint dimensions against existing board layouts. Ensure acoustic performance metrics meet system requirements.
