Procurement Notes
Verify the specific ordering suffix to ensure correct terminal type and acoustic specifications. Confirm RoHS compliance status as indicated in official documentation. Cross-reference the manufacturer part number with distributor catalogs to validate availability and lead times. Ensure the application circuit supports the required external drive signal for proper operation.
Selection Notes
Select this component when an external drive piezo transducer is required for through-hole assembly. Compare the 80 dB SPL and 4.1 kHz frequency against system acoustic requirements. Verify that the 5 VDC operating voltage aligns with the available supply rails. Consider the physical dimensions for enclosure clearance and mounting hole spacing.
Part Context
This component belongs to the PT series of piezoelectric transducers from Mallory Sonalert. These devices are designed for applications requiring high reliability and consistent acoustic performance. The series offers various frequencies and sound pressure levels to suit different alerting needs across industrial and consumer electronics markets.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Direct replacements must match the external drive requirement, mounting style, and electrical ratings. Generic piezo elements may not provide identical acoustic output or mechanical fit.
