Procurement Notes
Verify the specific suffix 'PPC' against official Mallory Sonalert documentation to confirm exact acoustic characteristics and packaging details. Ensure compatibility with the target PCB footprint and operating voltage requirements before integration.
Selection Notes
Select this component for applications requiring a compact, internally driven audible alert. Confirm that the 90dB output meets regulatory noise limits for the intended environment. Verify mechanical dimensions against available board space.
Part Context
This part belongs to the SBT5 series of piezoelectric buzzers. It shares the same form factor as variants like SBT5CMFL but differs in acoustic profile and specific application tuning. The series is characterized by low power consumption and reliable performance.
Replacement Considerations
Direct substitutes include SBT5GLHFPPC and SBT5PLMFPPC. Verify that the alternative part number matches the required voltage range and acoustic output specifications for the specific design.
