Substitute Part Grouping Explanation

The AT-2336-TWT-R qualifies as a direct substitute for the AT-24 based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by PUI Audio, Inc., ensuring design and quality consistency within the same product family
• Series: Both belong to the AT series
• Technology: Both utilize piezo transducer technology with external drive circuitry
• Frequency: Both operate at 3.6kHz, maintaining acoustic performance specifications
• Mounting Type: Both are through-hole mounted components
• Termination: Both use PC pins for circuit board connection

The AT-2336-TWT-R represents an active product with enhanced specifications, including rated voltage (12V), defined current consumption (8mA), and improved sound pressure level (90dB @ 12V, 10cm), making it suitable for applications requiring the core functional characteristics of the obsolete AT-24.

Engineering Selection Recommendations

The AT-2336-TWT-R is the designated substitute for the obsolete AT-24. Selection of this part is based on:

• Product Status Alignment: The AT-2336-TWT-R is an active product with current manufacturing support, eliminating obsolescence risk
• Regulatory Compliance: The AT-2336-TWT-R achieves ROHS3 compliance, whereas the AT-24 is RoHS non-compliant, making the substitute suitable for applications subject to modern environmental regulations
• Functional Equivalence: Both parts maintain identical frequency (3.6kHz), driver architecture (externally driven piezo transducer), and physical mounting characteristics (through-hole PC pins)
• Enhanced Specifications: The AT-2336-TWT-R provides defined electrical parameters (12V rated, 8mA supply current) and acoustic performance (90dB SPL), enabling precise circuit design and performance validation

Frequently Asked Questions (FAQ)

Q: Can the AT-2336-TWT-R be used as a direct replacement for the AT-24 in existing designs?

A: Yes. Both parts share identical frequency (3.6kHz), mounting type (through-hole), termination style (PC pins), and driver circuitry (externally driven piezo transducer). The AT-2336-TWT-R is designed as the active equivalent within the PUI Audio AT series.

Q: What are the key differences between the AT-24 and AT-2336-TWT-R?

A: The AT-24 specifications are not fully documented in available data. The AT-2336-TWT-R provides complete electrical specifications including 12V rated voltage, 3~18V operating range, 8mA supply current, and 90dB SPL at 12V/10cm. The AT-2336-TWT-R also includes feedback technology and achieves ROHS3 compliance.

Q: Are there physical dimension differences that affect PCB layout?

A: The AT-2336-TWT-R has documented dimensions of 0.906" diameter (23.00mm) and 0.492" maximum seated height (12.50mm). The AT-24 dimensions are not specified. Verify PCB footprint compatibility with the documented AT-2336-TWT-R dimensions before design finalization.

Q: Does the AT-2336-TWT-R require different driver circuitry than the AT-24?

A: No. Both parts are externally driven piezo transducers and use identical driver architecture. The AT-2336-TWT-R operates within a 3~18V range with 12V as the rated voltage, allowing flexible circuit design within this specification window.

Q: What is the regulatory status difference between these parts?

A: The AT-24 is RoHS non-compliant. The AT-2336-TWT-R is ROHS3 compliant, making it suitable for applications subject to RoHS directives and modern environmental regulations.
