Key Parameters

Substitute Part Grouping Explanation

Substitution of the AI-3622-P-S-12V-R is determined by the following critical parameters:

• Voltage Compatibility: Rated voltage of 12V DC with acceptable operating range overlap
• Technology Type: Piezo-based internally driven indicator technology
• Mounting Configuration: Panel mount with compatible termination interface
• Functional Output: Audible indication capability with sound pressure level suitable for the application
• Environmental Compliance: REACH and ECCN classification alignment

The AI-4228-P-C18-R qualifies as a substitute based on matching voltage rating (12V), identical technology (piezo, internally driven), compatible mounting type (panel mount), and equivalent regulatory status (REACH Unaffected, EAR99). Both components operate within the same product series (AI) and serve identical functional roles as DC-powered audible indicators.

Parameter Comparison

Engineering Selection Recommendations

The AI-4228-P-C18-R is an active product with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AI-3622-P-S-12V-R. Both components share identical voltage ratings and piezo technology, ensuring functional compatibility in 12V DC systems.

The substitute part demonstrates enhanced specifications: increased sound pressure level (108dB versus 105dB), extended operating temperature range (-30°C to 85°C versus -20°C to 60°C), and significantly reduced current consumption (16mA versus 85mA). The AI-4228-P-C18-R carries cUL and UL certifications, providing additional regulatory compliance documentation compared to the main part.

Physical differences include increased diameter (42.50mm versus 36.00mm) and modified termination tab dimensions (0.256" versus 0.248"). Panel mounting compatibility requires verification of available space and terminal clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the AI-4228-P-C18-R directly replace the AI-3622-P-S-12V-R in existing designs?

A: Both components operate at 12V DC with identical driver circuitry and piezo technology. Direct replacement is feasible from an electrical standpoint. Physical installation requires confirmation that the larger diameter (42.50mm versus 36.00mm) and modified terminal dimensions (0.256" versus 0.248") accommodate the existing panel cutout and wiring configuration.

Q: What are the key differences in operating characteristics?

A: The substitute operates at a higher frequency (2.9kHz versus 2.2kHz) and produces increased sound pressure level (108dB versus 105dB). Current consumption is substantially lower (16mA versus 85mA), reducing power supply requirements. Operating temperature range is extended on the substitute (-30°C to 85°C versus -20°C to 60°C).

Q: Are both parts compliant with the same regulatory standards?

A: Both components are REACH Unaffected and classified as EAR99. The substitute part includes additional cUL and UL certifications, providing enhanced regulatory documentation for applications requiring third-party approval.

Q: What is the voltage operating range compatibility?

A: The main part operates within 5 to 15V, while the substitute operates within 7 to 18V. Both ranges encompass the 12V rated voltage. Applications operating below 7V require the original part; applications operating above 15V require the substitute.

Q: How does the reduced current consumption affect system design?

A: The substitute's 16mA supply current versus the main part's 85mA represents an 81% reduction in power draw. This allows use of lower-capacity power supplies and reduces thermal load in the system, particularly beneficial in battery-powered or power-constrained applications.
