Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix if required, as variations may exist in packaging or minor specifications. Confirm that the through-hole footprint matches your PCB design constraints. Ensure the driving circuit can supply the necessary current rating for reliable operation at the selected voltage. Check for any specific environmental certifications required for your target market compliance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a simple, cost-effective audible alert is needed without complex driving requirements. The wide voltage tolerance allows flexibility in power supply design. Consider the 85dB SPL output for applications requiring moderate volume levels. The through-hole format is suitable for prototyping or high-reliability assemblies where surface mount options are not preferred.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezoelectric buzzer family, formerly associated with CUI Devices. These components are standard audio indicators used across various electronics sectors. The CPE series typically offers round designs with consistent acoustic performance. This specific model represents a mid-range option in terms of size and sound output.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 23.3mm diameter, 3.2kHz frequency, and through-hole termination style. Verify that alternative parts support the same 5-16V operating range and provide comparable SPL ratings. Ensure the replacement fits the existing PCB hole pattern and maintains similar height constraints.
