SBT5EHCMPPC

Overview

The SBT5EHCMPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for medical equipment applications. It features an internal driver circuit and accepts DC input within a voltage range of 3.3 to 5VDC. The device produces a supply failure melody with a sound pressure level of 90dB. It has a thickness of 44.45mm and utilizes through-hole mounting technology. The component is recognized under cUL standards, specifically complying with IEC60601-1-8 AMD1 requirements for medical audio indicators.

Feature Summary

• Generates a specific supply failure melody for critical system alerts
• Complies with IEC60601-1-8 AMD1 medical safety standards
• Operates on low voltage DC input suitable for portable devices

Applications

• Medical equipment power failure indication
• Healthcare monitoring systems alerting
• Portable diagnostic device status signaling

Procurement Notes

Verify the specific ordering suffix matches the required melody and acoustic output specifications. Confirm that the through-hole package style aligns with the target PCB layout. Ensure compliance with IEC60601-1-8 AMD1 is documented for the final assembly. Check RoHS status if environmental regulations apply to the manufacturing region.

Selection Notes

Select this component when a distinct supply failure tone is required in medical environments. The 90dB output ensures audibility in noisy clinical settings. The 3.3-5VDC operating range fits standard logic-level power supplies. Verify that the 44.45mm thickness accommodates the enclosure constraints.

Part Context

This part belongs to the SBT5 series of industrial-grade audio indicators from Mallory Sonalert. These components are engineered for reliability in demanding environments. The SBT5EHCMPPC variant is specifically tuned for medical compliance, distinguishing it from general-purpose alarm buzzers in the same product family.

Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific medical-compliant model. Replacement requires matching the IEC60601-1-8 AMD1 recognition, the specific failure melody, and the 90dB acoustic output at the specified voltage.
