SC628FP

Overview

The SC628FP is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a resonant frequency of 2800 Hz and produces a sound pressure level of 85 dB at a distance of 10 cm. The device requires a DC drive voltage ranging from 3 to 9 volts. It features a flat profile design with a total height of approximately 6.4 mm. The unit utilizes a two-wire connection interface for simple integration into electronic circuits.

Feature Summary

• Piezoelectric transduction mechanism for reliable acoustic output
• Compact low-profile form factor suitable for space-constrained enclosures
• Direct DC drive capability eliminating the need for external oscillators

Applications

• Portable consumer electronics audio signaling
• Industrial control panel status indication
• Medical device alarm systems

Procurement Notes

Verify the specific suffix codes on the component marking against the official Mallory Sonalert datasheet to confirm electrical characteristics and mechanical dimensions. Ensure the operating voltage range aligns with the system power supply before integration. Confirm environmental ratings if deployment involves extreme temperatures or humidity.

Selection Notes

Select this component when a compact, low-voltage audible indicator is required. The fixed frequency output suits applications where a specific tone pitch is necessary. Consider the 85 dB SPL rating relative to ambient noise levels in the target environment to ensure adequate audibility without excessive power consumption.

Part Context

This model belongs to the SC series of piezoelectric buzzers designed for general-purpose signaling. The series emphasizes reliability and consistent performance across various industrial and commercial applications. The SC628FP represents a standard configuration within this lineup, balancing size and acoustic output.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement matches the 2800 Hz frequency and 85 dB SPL requirements. Verify mechanical mounting hole patterns and terminal configurations to maintain compatibility with existing PCB layouts.
