Key Parameters

Substitute Part Grouping Explanation

The AT-1224-TWT-R qualifies as a direct substitute for the AT-08 based on the following alignment of core parameters:

• Same manufacturer: PUI Audio, Inc.
• Same series designation: AT
• Identical technology: Electromechanical/Magnetic
• Identical driver circuitry: Transducer, Externally Driven
• Identical mounting type: Through Hole
• Identical termination: PC Pins
• Active product status with current inventory availability

The AT-1224-TWT-R provides specified electrical and acoustic performance characteristics absent from the AT-08 documentation, enabling complete system integration.

Parameter Comparison

Engineering Selection Recommendations

The AT-1224-TWT-R is the designated substitute for the obsolete AT-08. Selection of this alternative is based on:

• Identical core functional parameters: same manufacturer, series, technology, driver circuitry, mounting type, and termination
• Active product status with established supply chain and inventory availability (33,895 units in stock)
• ROHS3 compliance, addressing regulatory requirements not met by the AT-08
• Documented electrical and acoustic specifications enabling precise system integration

Designs currently utilizing the AT-08 should transition to the AT-1224-TWT-R to ensure long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Why is the AT-08 being replaced? A: The AT-08 is classified as obsolete. The AT-1224-TWT-R is the active equivalent from the same manufacturer and series, ensuring continued availability and regulatory compliance.

Q: Are the AT-08 and AT-1224-TWT-R mechanically compatible? A: Both components use identical through-hole mounting and PC pin termination. The AT-1224-TWT-R has specified dimensions of 0.472" diameter and 0.343" maximum seated height, which should be verified against your PCB layout requirements.

Q: What are the electrical differences? A: The AT-1224-TWT-R operates at a rated voltage of 5V with a range of 3 to 8V, drawing 40mA supply current. The AT-08 specifications do not include voltage or current ratings. Verify that your driver circuit can supply 5V and 40mA to the substitute component.

Q: Does the AT-1224-TWT-R meet RoHS requirements? A: Yes, the AT-1224-TWT-R is ROHS3 compliant, whereas the AT-08 is RoHS non-compliant. This makes the substitute suitable for applications with RoHS regulatory requirements.

Q: What is the acoustic output of the AT-1224-TWT-R? A: The AT-1224-TWT-R produces 85dB sound pressure level at 5V measured at 10cm distance, operating at a frequency of 2.4kHz in single-tone mode.

Q: What packaging is available for the AT-1224-TWT-R? A: The AT-1224-TWT-R is supplied in tray packaging, suitable for automated assembly and bulk procurement.
