Key Parameters

Substitute Part Grouping Explanation

The AT-1620-TWT-R qualifies as a direct substitute for the AT-02 based on the following alignment of critical parameters:

• Same manufacturer: PUI Audio, Inc.
• Same series: AT
• Identical technology: Electromechanical/Magnetic
• Identical driver circuitry: Transducer, Externally Driven
• Identical mounting type: Through Hole
• Identical termination: PC Pins
• Same ECCN and HTSUS classifications

The AT-1620-TWT-R is an active product with current inventory availability, providing a direct path for obsolescence management of the AT-02.

Parameter Comparison

Engineering Selection Recommendations

The AT-1620-TWT-R is the designated substitute for the obsolete AT-02. Selection of this alternative is supported by:

• Active product status with confirmed inventory availability
• ROHS3 compliance, providing regulatory advantage over the non-compliant AT-02
• Identical core functional parameters: technology, driver circuitry, mounting, and termination
• Specified electrical and acoustic performance characteristics enabling direct circuit integration
• Consistent export classification and tariff coding

Designs currently utilizing the AT-02 should transition to the AT-1620-TWT-R to ensure long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the AT-1620-TWT-R directly replace the AT-02 in existing designs?

A: Yes. Both components share identical mounting type (through hole), termination (PC pins), technology (electromechanical/magnetic), and driver circuitry (externally driven transducer). The AT-1620-TWT-R provides specified performance parameters suitable for direct substitution.

Q: What is the primary reason for substituting the AT-02?

A: The AT-02 is classified as obsolete. The AT-1620-TWT-R is an active product with current manufacturing and inventory support, ensuring component availability for new and ongoing production.

Q: Are there compliance differences between these parts?

A: Yes. The AT-1620-TWT-R is ROHS3 compliant, while the AT-02 is RoHS non-compliant. For applications subject to RoHS regulations, the AT-1620-TWT-R is the required choice.

Q: What are the electrical specifications of the AT-1620-TWT-R?

A: The AT-1620-TWT-R operates at a rated voltage of 6V with a voltage range of 4 to 8V, draws 40mA supply current, and operates at a frequency of 2.048kHz with a sound pressure level of 90dB at 6V measured at 10cm.

Q: What packaging is available for the AT-1620-TWT-R?

A: The AT-1620-TWT-R is supplied in tray packaging.

Q: Are the physical dimensions compatible?

A: The AT-1620-TWT-R has a diameter of 0.630 inches (16.00mm) and a maximum seated height of 0.571 inches (14.50mm). Verify these dimensions against your PCB layout and enclosure constraints.
