AI-165 Equivalent & Substitute Parts

Part Overview

The AI-165 is an internally driven electromechanical magnetic buzzer rated for 12V DC operation with through-hole PC pin termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The AI-165 serves as an audio indicator in applications requiring direct DC voltage activation without external driver circuitry.

Key Parameters

Substitute Part Grouping Explanation

The AI-1223-TWT-12V-R qualifies as a direct substitute for the AI-165 based on the following alignment of critical parameters:

• Manufacturer: PUI Audio, Inc. (same manufacturer, same series AI)
• Rated Voltage: 12 V (identical)
• Input Type: DC (identical)
• Driver Circuitry: Indicator, Internally Driven (identical)
• Technology: Electromechanical/Magnetic (identical)
• Mounting Type: Through Hole (identical)
• Termination: PC Pins (identical)

The AI-1223-TWT-12V-R is an active product with enhanced specifications including defined frequency response (2.3kHz), 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-165 requirements and provide measurable performance characteristics suitable for direct replacement in equivalent circuit positions.

Parameter Comparison

Engineering Selection Recommendations

The AI-1223-TWT-12V-R is the designated substitute for the obsolete AI-165. Selection of this substitute is supported by:

• Functional equivalence across all core electrical parameters (12V DC, internally driven, electromechanical magnetic technology)
• Identical mechanical interface (through-hole mounting, PC pin termination)
• Active product status with full manufacturing support and availability
• ROHS3 compliance, providing regulatory advantage over the non-compliant AI-165
• Maintained REACH and EAR99 classification consistency
• Defined performance specifications (2.3kHz frequency, 85dB SPL, 30mA current, -20°C ~ 70°C operating range) enabling precise circuit integration

The AI-1223-TWT-12V-R accommodates voltage operation across 8 ~ 16V, providing operational margin beyond the nominal 12V rating of the original AI-165.

Frequently Asked Questions (FAQ)

Q: Can the AI-1223-TWT-12V-R directly replace the AI-165 in existing designs?

A: Yes. Both components share identical electrical characteristics (12V DC, internally driven), technology (electromechanical/magnetic), and mechanical interface (through-hole PC pins). The AI-1223-TWT-12V-R is pin-compatible and functionally equivalent for direct PCB substitution.

Q: What is the primary reason for substitution?

A: The AI-165 is classified as obsolete. The AI-1223-TWT-12V-R is an active product from the same manufacturer and series, ensuring continued availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Yes. The AI-165 is RoHS non-compliant, while the AI-1223-TWT-12V-R is ROHS3 compliant. Both maintain REACH Unaffected and EAR99 classification. The substitute provides improved regulatory alignment for new designs and production runs.

Q: What are the physical dimensions of the substitute?

A: The AI-1223-TWT-12V-R measures 0.472" diameter (12.00mm) with a maximum seated height of 0.382" (9.70mm). Verify PCB layout clearance for through-hole mounting.

Q: What is the current consumption of the AI-1223-TWT-12V-R?

A: The substitute draws 30mA at rated 12V operation. Confirm power supply capacity and circuit current budgeting for your application.

Q: Does the substitute operate across different voltage levels?

A: The AI-1223-TWT-12V-R is rated for 12V nominal operation with a specified voltage range of 8 ~ 16V. Operation outside this range is not specified and should not be assumed.
