Key Parameters

Substitute Part Grouping Explanation

Substitution of the AI-1027-TWT-12V-R is constrained by the following critical parameters:

Voltage Compatibility: The main part operates at 12V rated with a range of 7 ~ 15V. Substitute parts must be evaluated based on their rated voltage and operating range. The AI-1027-TWT-5V-R operates at 5V rated with a range of 3 ~ 7V, which does not overlap with the 12V system voltage requirement.

Frequency and Operating Mode: Both parts maintain identical frequency (2.7kHz) and single-tone operating mode, ensuring acoustic consistency.

Physical Form Factor: Both parts share identical dimensions (0.374" diameter, 0.217" maximum seated height) and mounting configuration (through-hole with PC pins), allowing direct mechanical substitution in PCB layouts.

Technology and Driver Circuitry: Both components utilize electromechanical/magnetic technology with internally driven indicator circuitry, maintaining functional equivalence in circuit operation.

Compliance Standards: Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The AI-1027-TWT-12V-R is classified as obsolete. The AI-1027-TWT-5V-R is the identified substitute part from PUI Audio, Inc., and maintains active product status with full ROHS3 compliance and REACH unaffected certification.

Direct voltage substitution is not applicable due to the distinct operating voltage ranges: the main part requires 12V operation (7 ~ 15V range), while the substitute operates at 5V (3 ~ 7V range). System redesign or voltage regulation is required if substitution is pursued.

Both components share identical physical dimensions, mounting configuration, frequency response, and operating temperature range, enabling mechanical and acoustic compatibility when voltage requirements are addressed through circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the AI-1027-TWT-5V-R directly replace the AI-1027-TWT-12V-R in a 12V circuit?

A: No. The AI-1027-TWT-5V-R is rated for 5V operation (3 ~ 7V range) and cannot be directly substituted in a 12V system without circuit modification. Operating the 5V part at 12V will cause component failure.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.374" diameter and 0.217" maximum seated height. Both use through-hole mounting with PC pin termination, allowing direct PCB layout compatibility.

Q: Do both parts produce the same acoustic output?

A: Both parts operate at 2.7kHz with single-tone mode. However, sound pressure levels differ: the 12V part produces 85dB at 12V (10cm), while the 5V part produces 80dB at 5V (10cm). Acoustic output is dependent on the applied voltage.

Q: What compliance certifications apply to both parts?

A: Both the AI-1027-TWT-12V-R and AI-1027-TWT-5V-R are ROHS3 compliant and REACH unaffected.

Q: What is the current consumption difference between these parts?

A: The 12V part draws 60mA at rated voltage, while the 5V part draws 30mA at rated voltage. Current consumption scales with the voltage rating and operating point.
