Procurement Notes
Verify the specific suffix 'CTPC' against official Mallory Sonalert documentation to confirm exact acoustic and mechanical specifications. Ensure compatibility with the required operating voltage range of 3.3-5VDC during integration. Confirm that the through-hole PC pin format matches the target PCB layout requirements before procurement.
Selection Notes
Select this component when a self-contained piezo buzzer with internal drive is required for low-voltage DC systems. The 3.3-5VDC operating range suits modern digital logic interfaces. Consider the through-hole PC pin style if surface-mount alternatives are unsuitable for the assembly process or mechanical stress requirements.
Part Context
This part belongs to the SBT series of audio indicators from Mallory Sonalert. These devices are engineered for robust performance in industrial environments. The series typically offers various acoustic outputs and mounting options to meet diverse design constraints for audible alerting systems.
Replacement Considerations
Consult Mallory Sonalert official substitution guides for direct equivalents. Verify that any alternative maintains the 3.3-5VDC input range, internal driver capability, and through-hole PC pin footprint to ensure functional interchangeability without redesign.
