Procurement Notes
This component is listed as discontinued by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verify end-of-life status and lead times carefully before design finalization. Consider alternative sourcing channels or qualified replacement parts to ensure supply chain continuity for existing production lines.
Selection Notes
Select this model when a 90 dBA acoustic output is required within a 24.3 mm form factor. Ensure the driving circuit provides a stable 15 V supply capable of delivering 16 mA. The flush mount design necessitates precise panel cutouts. Verify that the 3.6 kHz tone frequency aligns with the specific auditory warning requirements of the target application environment.
Part Context
Part of the Murata PIEZORINGER PK series, which specializes in compact piezoelectric buzzers and ringers. This series offers various voltage and acoustic options for industrial audio signaling. The PKB24SPCH36W1-B0 represents a specific variant optimized for higher sound pressure levels compared to standard low-profile indicators.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. As the part is discontinued, engineers must evaluate equivalent specifications from other manufacturers or consult Murata for recommended alternatives.
