Overview
The PKM13EPYH4000-A0 is a piezoelectric buzzer manufactured by Murata Electronics, designed for through-hole mounting on printed circuit boards. It operates at a rated voltage of 1.5 V with a maximum voltage range up to 30 V. The device generates an acoustic signal at a frequency of 4 kHz, achieving a sound pressure level of 70 dB measured at 1.5 V and 10 cm distance. It features PC pin termination and has a diameter of 12.6 mm (0.496 inches) with a maximum installation height of 7.40 mm (0.291 inches). The component functions within a temperature range of -40°C to 85°C.
Feature Summary
- Piezoelectric transduction mechanism for external drive applications
- Through-hole mounting with PC pin termination
- Single-tone audio output capability
Applications
- General purpose audible alerts in electronic devices
- Status indication in consumer electronics
- Security system sirens and alarms
Procurement Notes
Verify the End-of-Life status before finalizing designs, as official documentation indicates this product is subject to discontinuation. Confirm that alternative components meet the required acoustic and electrical specifications. Ensure compatibility with existing PCB footprints if transitioning from current inventory. Check for any specific handling requirements during assembly due to the through-hole nature of the component.
Selection Notes
Select this component when a low-voltage, single-frequency audible indicator is required for through-hole assembly. The 1.5 V rating suits battery-powered or low-voltage logic circuits. Consider the 70 dB output sufficient for general proximity alerts but verify against noise floor requirements. The compact 12.6 mm diameter allows for space-constrained layouts where surface-mount alternatives are not feasible.
Part Context
This part belongs to the PK series of piezoelectric buzzers from Murata Electronics. The series typically offers various form factors and acoustic outputs for different alerting needs. The PKM13EPYH4000-A0 specifically represents the 13mm class size with standard through-hole configuration, distinct from larger or surface-mount variants in the broader product line.
Replacement Considerations
Publicly confirmed substitute part numbers include CPT-1206-3TH-T, CPT-1207-5LTH-T, CPT-1255C-090, and OWPB-1360P3.5-40-03. Verify electrical parameters such as operating voltage and frequency match before substitution.
