AI-500 Equivalent & Substitute Parts

Part Overview

The AI-500 is an internally driven electromechanical magnetic buzzer rated at 12V with a 2.5kHz frequency, designed for through-hole mounting with 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-500 serves as an audio indicator in applications requiring DC-powered audible signaling.

Key Parameters

Substitute Part Grouping Explanation

The AI-5025-TWT-R qualifies as a substitute for the AI-500 based on the following alignment of critical parameters:

• Rated voltage: Both operate at 12V DC
• Frequency: Both generate 2.5kHz output
• Driver circuitry: Both feature internally driven indicator configuration
• Input type: Both accept DC input
• Mounting type: Both use through-hole mounting
• Termination: Both use PC pin termination
• Manufacturer: Both are manufactured by PUI Audio, Inc.

The primary difference is the technology implementation: the AI-500 uses electromechanical/magnetic technology, while the AI-5025-TWT-R uses piezo technology. Both technologies meet the functional requirements of the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The AI-5025-TWT-R is the designated substitute for the obsolete AI-500. Selection of this substitute is supported by:

• Active product status ensuring ongoing availability and manufacturing support
• ROHS3 compliance, addressing regulatory requirements not met by the AI-500
• Identical electrical operating parameters (12V, 2.5kHz, DC input, internally driven)
• Matching mechanical interface (through-hole mounting, PC pin termination)
• Documented operating temperature range and supply current specifications
• Equivalent functional performance as an audio indicator component

The transition from electromechanical/magnetic to piezo technology does not affect compatibility with the specified electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the AI-5025-TWT-R directly replace the AI-500 in existing designs?

A: Yes. Both components share identical rated voltage (12V), frequency (2.5kHz), driver circuitry (internally driven indicator), input type (DC), mounting type (through-hole), and termination (PC pins). The mechanical interface and electrical operating parameters are compatible.

Q: What is the primary difference between these two buzzers?

A: The AI-500 uses electromechanical/magnetic technology, while the AI-5025-TWT-R uses piezo technology. Both technologies produce the required 2.5kHz output at 12V.
