PT-2736FPQ

Overview

The PT-2736FPQ is a self-drive piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 3 to 28 volts with a current rating of 10 mA. The device produces a single tone at a frequency of 3.5 kHz and achieves a sound pressure level of 90 dBA. It features solder pin termination for through-hole mounting and has physical dimensions of 30 mm in diameter by 10 mm in height.

Feature Summary

• Self-exciting piezoelectric design eliminates the need for external oscillators
• Wide operating voltage range supports diverse power supply environments
• Through-hole solder pin termination ensures secure board integration

Applications

• Industrial control panel status indicators
• Appliance operational alerts
• General purpose audio signaling systems

Procurement Notes

Verify the specific voltage tolerance and acoustic output requirements against the official Mallory Sonalert datasheet before procurement. Confirm that the through-hole mounting style and solder pin configuration match the target PCB layout. Ensure the component meets all relevant regulatory standards required for the intended end-use application.

Selection Notes

Select this component when a self-driven, wide-voltage piezoelectric buzzer is required for through-hole assembly. The 3-28 VDC range offers flexibility compared to fixed-voltage alternatives. Consider the 90 dBA output and 3.5 kHz frequency for audible alerting needs in standard industrial or consumer environments.

Part Context

This part belongs to the PT series of piezoelectric buzzers from Mallory Sonalert. It is designed as a direct replacement for similar board-mount transducers requiring self-excitation. The series is characterized by robust construction and consistent acoustic performance across varying input voltages within the specified range.

Replacement Considerations

Cross-reference with PT-2735FPQ for dual-tone variants or other PT-series models for different acoustic profiles. Verify mechanical fit and electrical compatibility with existing circuit designs before substitution.
