Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific revision of the datasheet to confirm RoHS compliance status and exact dimensional tolerances. Ensure the driving circuit provides the required peak-to-peak voltage without exceeding the 30V maximum rating. Confirm that the 5 kHz frequency aligns with the target application's acoustic requirements. Check for any recent manufacturing changes or component substitutions documented in product change notices.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, externally driven piezo buzzer is required. The 16.5 mm diameter fits standard panel cutouts. The 80 dB output is suitable for moderate noise environments. Consider the -30°C to 85°C range for environmental suitability. Compare against internally driven models if circuit complexity needs reduction.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezo buzzer family, formerly associated with CUI Devices. It serves as a passive audio indicator component. The series includes various diameters and frequencies. The CPE-150 specifically targets applications needing a balance between size and acoustic output. It complements active buzzers where driver flexibility is preferred.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other 16.5 mm externally driven piezo buzzers from the same manufacturer. Verify pinout compatibility and mechanical dimensions before substitution. Cross-reference with CUI Devices legacy part numbers if transitioning from older designs.
