AI-383 Equivalent & Substitute Parts

Part Overview

The AI-383 is a piezo buzzer manufactured by PUI Audio, Inc., designed as an internally driven indicator with a 12V rated voltage and 2.8kHz operating frequency. It features a 42.5mm panel mount form factor with screw terminal and quick connect tab termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The AI-4328-P-C28-R qualifies as a direct substitute for the AI-383 based on the following alignment of critical parameters:

• Manufacturer & Series: Both components are manufactured by PUI Audio, Inc. within the AI series
• Technology & Driver Type: Both utilize piezo technology with internally driven indicator circuitry
• Frequency: Both operate at 2.8kHz
• Mounting & Termination: Both feature 42.5mm panel mount configuration with identical screw terminal and quick connect tab termination
• Physical Dimensions: Diameter matches at 1.673" (42.50mm); height difference is minimal (1.299" vs 1.319")

The AI-4328-P-C28-R represents an active product with enhanced specifications including expanded voltage range (4-28V vs fixed 12V), documented sound pressure level (91dB @ 12V, 10cm), and RoHS3 compliance, addressing the obsolescence of the original AI-383.

Parameter Comparison

Engineering Selection Recommendations

The AI-4328-P-C28-R is the appropriate substitute for the obsolete AI-383 based on product lifecycle status and regulatory compliance. The substitute maintains functional equivalence across all critical parameters: identical frequency response, mounting configuration, and termination style ensure direct mechanical and electrical compatibility within existing designs.

The AI-4328-P-C28-R offers improved regulatory standing through ROHS3 compliance, addressing environmental and supply chain requirements that may apply to new production or system updates. The expanded voltage range (4-28V) and documented electrical characteristics (7mA supply current, 91dB SPL) provide enhanced design flexibility compared to the original specification.

Physical dimensions remain compatible, with the height difference of 0.020" (0.50mm) falling within typical mechanical tolerances for panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the AI-4328-P-C28-R directly replace the AI-383 in existing designs?

A: Yes. Both components share identical frequency (2.8kHz), mounting type (panel mount), termination style (screw terminal with quick connect tab), and physical diameter (42.5mm). The height difference of 0.020" is negligible for panel mount applications. Electrical compatibility is maintained at the rated 12V operating point.

Q: What are the key differences between these components?

A: The AI-4328-P-C28-R is an active product with documented specifications including sound pressure level (91dB @ 12V, 10cm), supply current (7mA), and operating temperature range (-30°C ~ 85°C). It supports both AC and DC input, whereas the AI-383 specifies DC only. The substitute achieves ROHS3 compliance, addressing regulatory requirements not met by the obsolete AI-383.

Q: Are there any mechanical compatibility concerns?

A: No. Both components use identical 42.5mm diameter housings and 0.256" (6.50mm) quick connect tab termination. The 0.020" height difference does not affect panel mount installation or clearance in standard applications.

Q: Does the expanded voltage range of the AI-4328-P-C28-R affect compatibility?

A: No. The substitute maintains the 12V rated voltage specification of the original part. The 4-28V operating range provides additional design flexibility for applications requiring voltage variation, but does not impact direct substitution at the original 12V operating point.

Q: What is the significance of RoHS3 compliance on the substitute?

A: RoHS3 compliance indicates the AI-4328-P-C28-R meets current environmental and hazardous substance restrictions applicable to electronic components. This addresses regulatory requirements for new production and system updates where the non-compliant AI-383 may no longer be acceptable.
