Procurement Notes

Verify the specific suffix 'Q' against the manufacturer's official documentation to confirm compliance requirements and material composition. Ensure the ordering information matches the exact part number to avoid discrepancies in acoustic performance or mounting specifications.

Selection Notes

Select this component when a low-profile, surface-mount magnetic buzzer is required for compact circuit designs. It is suitable for applications needing a constant audible alert with minimal power consumption and standard 3V logic compatibility.

Part Context

This component belongs to the AST series of piezoelectric and magnetic indicators from Mallory Sonalert. It serves as an internal drive solution for general-purpose audio signaling within the broader portfolio of audible warning devices offered by the manufacturer.

Replacement Considerations

Consult the Mallory Sonalert cross-reference sheet for verified substitutes for obsolete Murata buzzers. Verify pinout and acoustic parameters before substituting with other SMD buzzers.
