Engineering Selection Recommendations

The AI-2332-TWT-12V-R is the designated substitute for the obsolete AI-258. Both components share identical electrical specifications for voltage, frequency, and driver configuration, ensuring functional compatibility in existing circuit designs.

The AI-2332-TWT-12V-R offers additional advantages: it maintains active product status with ongoing manufacturer support, provides ROHS3 compliance compared to the non-compliant AI-258, and includes documented performance specifications (85dB SPL, 13mA supply current) that were not available for the original part.

The substitute maintains identical mounting and termination characteristics, allowing direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the AI-2332-TWT-12V-R replace the AI-258 in existing designs?

A: Yes. Both components operate at 12V DC with 3.2kHz frequency output and use identical through-hole PC pin termination. No circuit modifications are required.

Q: What is the voltage operating range for the substitute?

A: The AI-2332-TWT-12V-R operates across 3V to 20V, providing broader voltage compatibility than the rated 12V specification. The component is rated at 12V and functions within this extended range.

Q: Are there physical dimension differences between the parts?

A: The AI-258 dimensions are not documented. The AI-2332-TWT-12V-R measures 23.30mm diameter with 10.70mm maximum seated height. Verify PCB layout clearances before implementation.

Q: What compliance differences exist between these parts?

A: The AI-258 is RoHS non-compliant. The AI-2332-TWT-12V-R is ROHS3 compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: Is the substitute available in the same packaging?

A: The AI-258 packaging is not specified. The AI-2332-TWT-12V-R is supplied in bulk packaging.
