AT-152 Equivalent & Substitute Parts

Part Overview

The AT-152 is a through-hole piezo buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven piezo device operating at 4kHz. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and repair applications. The AT-152 serves as an acoustic signaling element in applications requiring piezo-based transducer functionality with through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the AT-1740-TT-3-R directly replace the AT-152 in existing designs?

A: Yes. Both parts share identical mounting type (through-hole), termination style (PC pins), frequency (4kHz), and driver architecture (externally driven piezo transducer). The AT-1740-TT-3-R is mechanically and functionally compatible with AT-152 applications.

Q: What are the key differences between AT-152 and AT-1740-TT-3-R?

A: The AT-1740-TT-3-R is an active product with fully specified electrical parameters (3V rated voltage, 1–30V operational range, 1mA current, 78dB SPL @ 3V/10cm), defined operating temperature range (–20°C to 70°C), and ROHS3 compliance. The AT-152, being obsolete, lacks these detailed specifications.

Q: Are there packaging differences between these parts?

A: The AT-152 packaging is not specified. The AT-1740-TT-3-R is supplied in tray packaging. Verify tray packaging compatibility with your assembly process requirements.

Q: Does the AT-1740-TT-3-R meet current regulatory standards?

A: Yes. The AT-1740-TT-3-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What voltage should be applied to the AT-1740-TT-3-R?

A: The AT-1740-TT-3-R is rated for 3V operation and supports a functional range of 1–30V. Design circuits to operate within this voltage range for optimal performance and component longevity.
