• Alarm systems in industrial control units

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and electrical tolerances. Ensure the ordering suffix matches the required terminal configuration. Cross-reference the manufacturer's official documentation for safety certifications and environmental compliance status before integration into final designs.

Selection Notes

Select this component where a 2kHz resonant frequency aligns with system requirements. Consider the 75dBA output level relative to enclosure acoustics. Verify that the 20V maximum rating exceeds the circuit's peak operating voltage. Confirm through-hole compatibility with the target PCB layout.

Part Context

This part belongs to TDK's line of piezoelectric sounders designed for general-purpose audio indication. It serves as a discrete acoustic output device within electronic assemblies requiring simple, reliable signaling without complex driver circuits.

Replacement Considerations

Consult TDK's official substitution guide for equivalent piezo sounders. Verify matching resonant frequency and sound pressure levels. Ensure physical footprint and terminal pitch compatibility with existing PCB layouts.
