Procurement Notes
Verify the current lifecycle status before procurement, as similar PKM series components have been subject to discontinuation notices. Confirm that the 12V rating and 4kHz frequency align with the target circuit design requirements. Ensure through-hole soldering processes are compatible with the pin termination style specified in the official datasheet.
Selection Notes
Select this component when a compact, high-intensity audible alert is required for through-hole PCB designs. The 12V rating suits standard logic-level power supplies. Consider the 85 dB output for environments requiring clear auditory feedback without excessive volume. Verify mechanical clearance for the 13 mm diameter during layout.
Part Context
This part belongs to the PKM series of piezoelectric buzzers from Murata Electronics. The series offers various sizes and electrical ratings for different acoustic needs. The PKM13EPYH4002-B0 specifically targets applications needing a balance between size and sound pressure level using a simple external drive interface.
Replacement Considerations
Check for direct substitutes within the PKM series with matching 12V and 4kHz specifications. Verify mechanical footprint compatibility if replacing on existing boards. Consult official Murata documentation for any updated product line recommendations due to potential lifecycle changes.
