PS1740P02 Equivalent & Substitute Parts

Part Overview

The PS1740P02 is an externally driven piezo buzzer transducer rated at 3V with a 17mm diameter form factor and through-hole mounting. This component operates at 4kHz with a sound pressure level of 75dB at 3V measured at 10cm distance. The PS1740P02 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can PS1740P02E be used as a direct replacement for PS1740P02 in existing designs?

A: Yes. PS1740P02E is functionally and mechanically identical to PS1740P02. All electrical parameters, physical dimensions, and mounting characteristics are equivalent. Direct substitution requires no circuit modifications or PCB layout changes.

Q: What is the difference between PS1740P02 and PS1740P02E?

A: The primary differences are product status and packaging. PS1740P02 is obsolete, while PS1740P02E is active. PS1740P02E also carries ROHS3 Compliant certification. No functional or performance differences exist between the two parts.

Q: Are there any compatibility concerns with the through-hole PC pin termination?

A: No. Both parts use identical PC pin termination and 17mm through-hole mounting configuration. Existing PCB designs require no modification for component substitution.

Q: What is the operating frequency range for these buzzers?

A: Both PS1740P02 and PS1740P02E operate at a fixed frequency of 4kHz in single-tone mode. These are externally driven transducers requiring external signal generation.

Q: What voltage should be applied to these piezo buzzers?

A: The rated voltage is 3V. The maximum voltage range is 30V. Operation within the rated 3V specification ensures specified acoustic output of 75dB SPL at 10cm distance.

Q: Are these parts suitable for high-temperature applications?

A: The operating temperature range is -10°C to 70°C. Applications requiring operation outside this range require alternative component selection.
