AI-3039 Equivalent & Substitute Parts

Part Overview

The AI-3039 is a through-hole piezo buzzer manufactured by PUI Audio, Inc., designed for 12V DC applications with an internally driven indicator circuit. This component operates at 3.9kHz and is classified as obsolete. Due to its obsolete status and limited current inventory (655 pcs), identifying compatible substitute parts is essential for ongoing design support and production continuity. The substitute identified maintains functional equivalence while offering improved availability and active product status.

• Functional Equivalence: Both parts maintain identical voltage rating, frequency, technology, mounting configuration, and termination type
• Extended Specifications: The substitute provides documented electrical characteristics (15mA supply current, 100dB SPL @ 12V/10cm) and operating temperature range (-20°C ~ 80°C), enabling more precise circuit design validation

For applications currently using the AI-3039, transition to the AI-3039-TWT-12V-R is recommended to ensure long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the AI-3039-TWT-12V-R be used as a direct replacement for the AI-3039?

A: Yes. Both parts share identical voltage rating (12V), frequency (3.9kHz), piezo technology, internally driven indicator circuitry, through-hole mounting, and PC pin termination. The substitute is functionally equivalent for DC-powered applications requiring 3.9kHz piezo buzzer operation.

Q: What is the primary reason to substitute the AI-3039?

A: The AI-3039 is classified as obsolete. The AI-3039-TWT-12V-R is an active product with superior inventory availability and ROHS3 compliance, making it the appropriate choice for new designs and production continuity.

Q: Are there any dimensional differences between these parts?

A: The AI-3039 dimensional specifications are not provided in the technical data. The AI-3039-TWT-12V-R has a diameter of 1.181" (30.00mm) and seated height of 0.780" (19.80mm). PCB layout compatibility should be verified against original design documentation.

Q: Does the substitute support the same voltage range as the original?

A: The AI-3039 voltage range is not specified. The AI-3039-TWT-12V-R supports an extended voltage range of 3–24V while maintaining a 12V nominal rating, providing greater design flexibility for applications with variable supply voltages.

Q: What is the packaging difference?

A: The AI-3039 packaging is not specified. The AI-3039-TWT-12V-R is supplied in tray packaging, which is standard for through-hole component distribution.

Q: Is the substitute RoHS compliant?

A: Yes. The AI-3039-TWT-12V-R is ROHS3 compliant, whereas the AI-3039 is RoHS non-compliant. This makes the substitute suitable for applications subject to RoHS regulatory requirements.
