Procurement Notes
Verify the specific suffix '05Q' against the official Mallory Sonalert datasheet to confirm voltage and acoustic specifications. Ensure the ordering part number matches the required medical certification status. Confirm surface mount footprint compatibility with PCB layout before procurement.
Selection Notes
Select this component for applications requiring low-profile audio indication in space-constrained enclosures. The 5V operating voltage suits battery-powered or logic-level systems. Verify that the external drive circuit can provide sufficient current for the specified 80mA load.
Part Context
This part belongs to the AST series of board-mount buzzers from Mallory Sonalert. It is designed for high-reliability audible signaling in professional and medical environments. The magnetic construction offers robust performance compared to piezoelectric alternatives in certain frequency ranges.
Replacement Considerations
Consult Mallory Sonalert's cross-reference sheet for obsolete Murata buzzers. Verify mechanical footprint and electrical parameters before substituting with other surface-mount magnetic buzzers.
