Procurement Notes

Verify the specific suffix configuration against official Mallory documentation to ensure correct voltage and acoustic specifications. Confirm RoHS compliance status and cUL recognition requirements with the manufacturer or authorized distributor before finalizing procurement orders.

Selection Notes

Select this component when a 9-12 VDC operating range and 90 dB output are required. Ensure the PCB layout accommodates the 44.45 mm diameter and 14.00 mm height constraints. Verify that the target application supports internally driven piezoelectric buzzers rather than passive types.

Part Context

This part belongs to the SBT series of board-mount audio indicators. It utilizes piezoelectric technology for sound generation. The product line includes various voltage and acoustic options, with this specific model designated for 9-12 VDC applications requiring high volume output.

Replacement Considerations

Consult official Mallory cross-reference documents for verified substitutes. Generic replacements may not match the specific melody mode or internal driver characteristics.
