CPE-168

Alarms, Buzzers, And Sirens Overview

The CPE-168 is a discontinued piezoelectric audio transducer manufactured by Same Sky (formerly CUI Devices). It features a 13.00 mm diameter form factor designed for through-hole PC pin mounting. The device operates with a maximum peak-to-peak voltage of 30 V and includes an integrated driving circuit. Official documentation specifies a resonant frequency of 4.0 kHz. This component serves as a passive sound indicator for electronic assemblies requiring compact, direct-drive acoustic signaling.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated driving circuit simplifies interface requirements
• Compact 13 mm piezoelectric design
• Through-hole PCB mounting configuration

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems
• Industrial control panel indicators
• Consumer appliance status alerts

Alarms, Buzzers, And Sirens Procurement Notes

This component is officially obsolete and no longer manufactured by Same Sky. Procurement must focus on verified substitute part numbers from the manufacturer's current portfolio. Verify that replacement devices match the original electrical specifications and mechanical footprint to ensure compatibility with existing designs.

Alarms, Buzzers, And Sirens Selection Notes

Designers should evaluate current Same Sky piezo transducers offering similar voltage ratings and acoustic output levels. Ensure the selected replacement supports the required operating frequency and maintains the through-hole mounting style. Cross-reference datasheets to confirm interface compatibility with existing drive circuits.

Alarms, Buzzers, And Sirens Part Context

The CPE series represents Same Sky's line of piezoelectric audio indicators. These components are engineered for reliable acoustic signaling in space-constrained applications. The CPE-168 specifically targets low-profile installations where integrated drive electronics reduce external component count.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult Same Sky's official substitution guide for active equivalents. Verify that alternative models maintain the 13 mm diameter constraint and through-hole termination style to preserve board layout integrity.
