Key Parameters

Substitute Part Grouping Explanation

The AI-1622-TWT-12V-R qualifies as a direct substitute for the AI-195 based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by PUI Audio, Inc., ensuring design and quality consistency within the same product family
• Series: Both belong to the AI series
• Rated Voltage: Both operate at 12V DC
• Driver Circuitry: Both feature internally driven indicator functionality
• Input Type: Both accept DC input
• Technology: Both utilize electromechanical/magnetic technology
• Mounting Type: Both employ through-hole mounting
• Termination: Both use PC pins for circuit board connection

The AI-1622-TWT-12V-R is an active product with enhanced specifications including defined frequency response (2.2kHz), sound pressure level (85dB @ 12V, 10cm), current consumption (30mA), and operating temperature range (-20°C ~ 70°C). These additional parameters do not conflict with the AI-195 requirements and represent a functional upgrade path.

Parameter Comparison

Engineering Selection Recommendations

The AI-1622-TWT-12V-R is the designated substitute for the obsolete AI-195. Selection of this part is supported by:

• Active product status ensuring ongoing availability and manufacturer support
• ROHS3 compliance, providing environmental and regulatory alignment for new designs
• Identical core electrical and mechanical interface specifications (12V DC, through-hole PC pins, internally driven operation)
• Defined performance parameters (2.2kHz frequency, 85dB SPL, 30mA current draw) enabling accurate circuit design and validation
• Extended operating temperature range (-20°C ~ 70°C) supporting broader application environments

For applications currently using the AI-195, direct substitution with the AI-1622-TWT-12V-R is appropriate where the specified performance characteristics align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the AI-1622-TWT-12V-R directly replace the AI-195 in existing designs?

A: Yes. Both parts share identical voltage rating (12V DC), driver circuitry (internally driven indicator), mounting type (through-hole), and termination style (PC pins). The AI-1622-TWT-12V-R provides defined performance specifications that do not conflict with AI-195 applications.

Q: What is the physical size difference between these parts?

A: The AI-1622-TWT-12V-R has a defined diameter of 0.630" (16.00mm) and height of 0.559" (14.20mm). The AI-195 physical dimensions are not specified in available documentation. PCB layout verification is necessary to confirm mechanical fit.

Q: Does the AI-1622-TWT-12V-R require different power supply specifications?
