Procurement Notes
Verify the specific ordering suffix and package type against the manufacturer's current datasheet to ensure compatibility with your assembly process. Confirm that the voltage rating aligns with your system's power supply specifications before procurement. Check for RoHS compliance documentation if required by your regulatory standards.
Selection Notes
Select this component when a compact, high-output audible alarm is needed for PCB integration. The 4.0 kHz frequency provides distinct audibility, while the 85 dBA rating ensures clear signaling in moderate noise environments. Ensure sufficient clearance around the 13.8 mm footprint during layout design.
Part Context
This part belongs to the PT series of board-mount buzzers from Mallory Sonalert. The series offers various frequencies and sound levels tailored for different alerting needs. The PT-1340P-PQ specifically targets applications requiring a balance of size constraints and high decibel output using standard through-hole assembly techniques.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for verified equivalents. Direct replacements must match the 4.0 kHz frequency, 85 dBA SPL, and 5-25VPP operating range to maintain performance integrity.
