AT-23 Equivalent & Substitute Parts

Part Overview

The AT-23 is a through-hole piezo buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven piezo acoustic component. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design and procurement requirements. The AT-23 serves applications requiring piezo-based sound generation with PC pin termination and through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

The AT-2830-TWT-R qualifies as a direct substitute based on the following alignment criteria:

Matching Parameters:

• Manufacturer: PUI Audio, Inc. (same OEM)
• Series: AT (same product family)
• Technology: Piezo (same acoustic technology)
• Driver Circuitry: Transducer, Externally Driven (identical functional classification)
• Mounting Type: Through Hole (same PCB integration method)
• Termination: PC Pins (identical electrical connection)
• ECCN: EAR99 (same export classification)
• HTSUS: 8531.80.9041 (same tariff classification)

The AT-2830-TWT-R represents an active product with enhanced specifications, including defined voltage rating (12V), frequency (3kHz), sound pressure level (93dB @ 12V, 10cm), and operating temperature range (-30°C ~ 85°C). This substitute maintains mechanical and electrical compatibility while providing ROHS3 compliance, addressing regulatory requirements absent in the obsolete AT-23.

Parameter Comparison

Engineering Selection Recommendations

The AT-2830-TWT-R is the designated substitute for the obsolete AT-23 based on product lifecycle status and regulatory compliance. The AT-23, classified as obsolete, is no longer supported by the manufacturer for new designs or ongoing procurement. The AT-2830-TWT-R maintains identical mechanical and electrical interface characteristics while providing:

• Active product status with manufacturer support
• ROHS3 compliance, meeting current environmental regulations
• Defined electrical and acoustic specifications enabling precise circuit design
• Extended operating temperature range (-30°C ~ 85°C)
• Washable rating for applications requiring environmental durability

For applications where the AT-23 was previously specified, direct substitution with the AT-2830-TWT-R is supported by matching mounting, termination, and driver circuitry classifications. The enhanced specification set of the AT-2830-TWT-R provides additional design flexibility without requiring circuit topology modifications.

Frequently Asked Questions (FAQ)

Q: Can the AT-2830-TWT-R directly replace the AT-23 in existing designs?

A: Yes. Both components share identical mounting type (through hole), termination method (PC pins), driver circuitry classification (externally driven transducer), and piezo technology. Physical and electrical interfaces are compatible.

Q: What is the primary reason for substitution?

A: The AT-23 is classified as obsolete and no longer manufactured. The AT-2830-TWT-R is an active product from the same manufacturer and series, ensuring ongoing availability and manufacturer support.

Q: Does the AT-2830-TWT-R meet current regulatory requirements?

A: Yes. The AT-2830-TWT-R is ROHS3 compliant and REACH unaffected, meeting current environmental and chemical regulations. The AT-23 is RoHS non-compliant.

Q: Are there dimensional differences between these components?

A: The AT-23 dimensional specifications are not provided in the technical data. The AT-2830-TWT-R has a diameter of 1.122" (28.50mm) and maximum seated height of 0.520" (13.20mm). Physical compatibility should be confirmed for space-constrained applications.

Q: What packaging options are available?

A: The AT-23 is available in standard packaging. The AT-2830-TWT-R is supplied in bulk packaging, suitable for production assembly environments.

Q: Are both components from the same manufacturer?

A: Yes. Both the AT-23 and AT-2830-TWT-R are manufactured by PUI Audio, Inc., and belong to the AT series product family.
