Procurement Notes

Verify the current lifecycle status as this part is scheduled for obsolescence and discontinuation by the manufacturer. Confirm availability of alternative components or last-time buy options before finalizing procurement plans to ensure long-term supply chain stability for production runs.

Selection Notes

Select this component when a low-profile, externally driven piezoelectric buzzer is required for through-hole assembly. Ensure the driving circuit can provide the necessary 3Vp-p signal at 2 kHz. Consider the end-of-life status when designing new products requiring long-term maintenance support.

Part Context

This component belongs to the PKM22 series of piezoelectric buzzers from Murata Electronics. The series is characterized by low power consumption, contactless operation, and high reliability. These buzzers are commonly used in consumer electronics where clear audio feedback is needed without complex driver circuits.

Replacement Considerations

Check for direct substitutes within the PKM22 family, such as PKM22EPPH4012-B0, noting differences in frequency and sound pressure level. Verify mechanical compatibility and electrical requirements before substituting.
