Procurement Notes
Verify the specific suffix 'CTPC' against official Mallory Sonalert documentation to confirm exact electrical characteristics and mechanical dimensions. Ensure compatibility with existing PCB layouts regarding through-hole spacing and operating temperature ranges before integration.
Selection Notes
Select this component when an internally driven solution is required to simplify circuit design. The 2.075 kHz frequency provides distinct audibility, while the 85 dB output ensures clear signaling in moderate noise environments. Confirm voltage requirements align with the 3.3V to 5VDC operational window.
Part Context
This part belongs to the SBT5 series of industrial buzzers from Mallory Sonalert. The series is characterized by robust construction suitable for demanding environments. The SBT5CLMCTPC variant specifically integrates internal driving electronics, distinguishing it from externally driven counterparts.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may not match the specific 2.075 kHz frequency or 85 dB acoustic output.
