• Pin-selectable DC operation
• Cardiac melody sound profile
• Through-hole mounting configuration

Applications

• Medical equipment alarms
• Industrial control panels
• Consumer appliance indicators

Procurement Notes

Verify the specific suffix PPC against official Mallory documentation to confirm lead-free status and RoHS compliance. Ensure the operating voltage matches the 5VDC requirement. Confirm that the 2.075kHz frequency aligns with system design constraints. Check for cUL recognition requirements in your target market.

Selection Notes

Select this component when an internally driven, high-volume audible indicator is required. The 5VDC specification suits standard logic-level circuits. The 44.45mm form factor fits standard panel cutouts. Verify that the 85dB output level meets regulatory noise limits for the intended enclosure.

Part Context

This part belongs to the SBT series of piezo buzzers from Mallory Sonalert. The series offers various melodies and drive types. The SBT5CMHFPPC specifically denotes a 5VDC cardic melody variant. It is designed for reliable long-term operation in electronic assemblies requiring clear auditory feedback.

Replacement Considerations

Consult official substitution lists for equivalent Mallory parts. Generic replacements may differ in frequency or acoustic output. Verify mechanical dimensions and pin compatibility before integration.
