- General purpose audible indicators in control panels
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage and acoustic specifications. Confirm RoHS compliance status and certification marks such as UL or CE if required for your target market. Check current availability as lead times may vary based on manufacturing schedules. Ensure the through-hole package dimensions match your PCB layout constraints before finalizing orders.
Selection Notes
Select this component when a high-decibel audible alert is required for 3.3V to 5V systems. It is appropriate for designs needing IEC-compliant signaling without complex driver circuits. Consider the 44.45mm form factor for panel or chassis mounting where space permits. Evaluate the operating temperature range against your environmental conditions to ensure long-term reliability.
Part Context
This part belongs to Mallory Sonalert's line of medical and industrial piezo buzzers. These devices are characterized by their self-oscillating nature and high efficiency. The series is widely used in healthcare and heavy industry where clear, loud auditory warnings are critical for safety and operational feedback.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement matches the 3.3-5V DC input, 90dB SPL, and 44.45mm mounting footprint. Verify that alternative parts maintain equivalent IEC compliance and thermal performance ratings.
