AI-384 Piezo Buzzer 220V Panel Mount - Equivalent & Substitute Parts

Part Overview

The AI-384 is a piezo buzzer designed for 220V AC/DC applications with panel mount configuration and screw terminal connectivity. This component functions as an internally driven indicator buzzer with a 42.5mm diameter form factor. The AI-384 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. The substitute part AI-4328-P-FP250-R provides functional continuity while offering enhanced specifications and current product status.

Substitute Part Grouping Explanation

The AI-4328-P-FP250-R qualifies as a direct substitute for the AI-384 based on the following critical parameters:

• Identical manufacturer (PUI Audio, Inc.) and series (AI)
• Matching rated voltage (220V) with extended voltage range capability (60-250V)
• Identical mounting configuration (Panel Mount)
• Identical termination type (Screw Terminal, Quick Connect Tab - 0.256")
• Identical physical diameter (1.673" / 42.50mm)
• Compatible height dimensions (34.60mm vs. 33.00mm - negligible difference for panel mount applications)
• Identical input type support (AC, DC)
• Identical technology platform (Piezo)

The AI-4328-P-FP250-R is an active product with enhanced electrical specifications including defined frequency response (2.8kHz), sound pressure level (91dB @ 220V, 10cm), current consumption (16mA), and operating temperature range (-30°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

The AI-4328-P-FP250-R is the appropriate substitute for the obsolete AI-384. Selection rationale is based on:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance of the substitute addresses regulatory requirements not met by the original part
• Mechanical compatibility confirmed through identical mounting, termination, and form factor specifications
• Electrical compatibility established through matching voltage rating and input type support
• The 0.5mm height difference (34.60mm vs. 33.00mm) presents no functional impact for panel mount applications

For applications requiring the AI-384, transition to the AI-4328-P-FP250-R maintains functional equivalence while providing enhanced compliance posture and product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the AI-4328-P-FP250-R directly replace the AI-384 in existing designs?

A: Yes. Both components share identical mounting type (Panel Mount), termination configuration (Screw Terminal, Quick Connect Tab - 0.256"), physical diameter (42.50mm), and voltage rating (220V AC/DC). The 0.5mm height difference is negligible for panel mount applications.

Q: What is the primary reason for substitution?

A: The AI-384 is classified as obsolete. The AI-4328-P-FP250-R is an active product from the same manufacturer and series, ensuring continued availability and support.

Q: Are there compliance differences between these parts?

A: Yes. The AI-384 is RoHS non-compliant, while the AI-4328-P-FP250-R is ROHS3 compliant. Both maintain REACH Unaffected status. For applications subject to RoHS requirements, the substitute provides necessary regulatory alignment.

Q: What additional specifications does the AI-4328-P-FP250-R provide?

A: The substitute includes defined operating parameters: frequency (2.8kHz), sound pressure level (91dB @ 220V, 10cm), current consumption (16mA), operating temperature range (-30°C to 85°C), and extended voltage range (60-250V). The original AI-384 specifications do not include these parameters.

Q: Are the electrical characteristics compatible?

A: Yes. Both components are internally driven piezo indicators supporting AC and DC input at 220V rated voltage. The AI-4328-P-FP250-R extends compatibility to 60-250V operation while maintaining the 220V rating.

Q: What is the packaging difference?

A: The AI-384 packaging is listed as "-" (unspecified). The AI-4328-P-FP250-R is supplied in Bulk packaging.
