Key Parameters

Substitute Part Grouping Explanation

Substitution of the AI-3035 is determined by alignment across the following critical parameters:

• Manufacturer & Series: Both main and substitute parts originate from PUI Audio, Inc., AI series, ensuring design consistency and performance predictability.
• Driver Circuitry & Input Type: Internally driven DC operation is maintained, eliminating the need for external driver modifications.
• Voltage Rating: The substitute part (AI-3035-TWT-3V-R) maintains the 3V rated voltage with an extended operating range of 2–5V, providing backward compatibility.
• Frequency: Both parts operate at 4.6kHz, preserving the audio signature and system integration.
• Technology: Piezo technology is consistent across both parts.
• Mounting & Termination: The substitute transitions from panel mount flange to through-hole PC pins, requiring mechanical redesign but maintaining electrical compatibility.

Engineering Selection Recommendations

The AI-3035-TWT-3V-R is the direct substitute for the obsolete AI-3035. Selection of this substitute is supported by:

• Product Status Alignment: The substitute is active and in production, ensuring long-term availability and supply chain stability.
• Electrical Compatibility: Identical rated voltage (3V), frequency (4.6kHz), and driver circuitry eliminate functional redesign requirements at the signal level.
• Compliance Improvement: The substitute achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet.
• Mechanical Redesign Requirement: Transition from panel mount flange to through-hole PC pins necessitates PCB layout and mechanical housing modifications. This change is the primary design consideration for implementation.

Frequently Asked Questions (FAQ)

Q: Can the AI-3035-TWT-3V-R be used as a direct drop-in replacement for the AI-3035?

A: Electrical operation is compatible. However, the mounting transition from panel mount flange to through-hole PC pins requires mechanical redesign of the mounting interface and PCB layout. The substitute cannot be installed without these modifications.

Q: What are the key electrical differences between these parts?

A: Both parts share identical rated voltage (3V), frequency (4.6kHz), and internal driver circuitry. The substitute provides additional specifications: 9mA supply current, 100dB SPL at 3V/10cm, and an extended operating range of 2–5V. These additions represent enhanced documentation rather than functional changes.

Q: Does the AI-3035-TWT-3V-R meet modern compliance standards?

A: Yes. The substitute achieves ROHS3 compliance, whereas the original AI-3035 is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the primary design consideration when switching to the AI-3035-TWT-3V-R?

A: The mounting type change from panel mount flange to through-hole PC pins is the critical design factor. PCB footprint, mechanical housing, and assembly process must be updated to accommodate the new termination style and 30mm diameter form factor.

Q: Is the substitute available in the same packaging as the original?

A: No. The AI-3035-TWT-3V-R is supplied in tray packaging, whereas the original part's packaging is not specified. Verify packaging requirements for your production and logistics processes.
