• Board mount configuration with solder pin connections

Applications

• Industrial equipment status indicators
• Alarm systems requiring high-volume alerts
• Electronic device audio feedback mechanisms

Procurement Notes

Verify component availability as this part number is listed as discontinued in current distributor catalogs. Confirm end-of-life status with the manufacturer before finalizing designs. Ensure alternative sourcing strategies are in place due to limited supply chain support for obsolete components.

Selection Notes

Select this component only if its specific 3.3 kHz resonant frequency and 110 dBA output align with acoustic requirements. Consider the 41.8 mm diameter for mechanical fitment constraints. Evaluate the discontinuation status against long-term production lifecycle needs.

Part Context

The AT-12 belongs to PUI Audio's AT series of piezoelectric transducers. This series focuses on providing reliable audio indication solutions through piezoelectric elements. The component represents a standard form factor within the manufacturer's historical product lineup for general-purpose alerting applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Consult manufacturer resources for direct replacements or evaluate similar piezoelectric transducers from other suppliers that match the 3.3 kHz frequency and 110 dBA specifications.
