Substitute Part Grouping Explanation

The AI-4329-P-SP28-R is identified as a substitute for the AI-3629-P-30V-R based on the following substitution criteria:

Both components share the following allowable parameters:

• Manufacturer: PUI Audio, Inc. (same product family)
• Series: AI (same product line)
• Driver Circuitry: Indicator, Internally Driven
• Input Type: DC
• Frequency: 2.9kHz (identical operating frequency)
• Mounting Type: Panel Mount
• Port Location: Top
• Operating Temperature Range: -20°C ~ 60°C (identical)
• Termination Style: Screw Terminal with Quick Connect Tab (compatible connector family)
• REACH Status: REACH Unaffected (same compliance status)
• ECCN: EAR99 (same export classification)

The substitute operates at a different rated voltage (12V vs. 30V) and employs piezo technology instead of electromechanical/magnetic technology. These differences require explicit system-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AI-4329-P-SP28-R is an active product with ROHS3 compliance, whereas the AI-3629-P-30V-R is obsolete. Selection of the substitute requires evaluation of the following system-level factors:

Voltage compatibility: The substitute operates at 12V rated voltage with a 4 ~ 28V range, compared to the main part's 30V rated voltage with a 5 ~ 32V range. System power supply specifications must accommodate this difference.

Acoustic output: The substitute produces 88dB @ 12V at 10cm versus 100dB @ 30V at 10cm for the main part. Applications requiring specific sound pressure levels must account for this 12dB reduction.

Current consumption: The substitute draws 6mA compared to 60mA for the main part, resulting in significantly lower power dissipation.

Technology and operating mode: The substitute employs piezo technology with pulse/slow operating mode, whereas the main part uses electromechanical/magnetic technology with single tone operation. System control circuitry must support the substitute's operating characteristics.

Physical dimensions: The substitute measures 1.693" diameter (43.00mm) versus 1.417" diameter (36.00mm) for the main part. Panel cutout and mounting space must accommodate the larger diameter.

Termination compatibility: Both components use screw terminal with quick connect tab connectors, with tab dimensions of 0.248" (6.30mm) for the main part and 0.256" (6.50mm) for the substitute. Connector compatibility must be verified.

Frequently Asked Questions (FAQ)

Q: Can the AI-4329-P-SP28-R directly replace the AI-3629-P-30V-R without circuit modifications?

A: No. The substitute operates at 12V rated voltage versus 30V for the main part. System power supply and control circuitry must be evaluated for compatibility. The substitute also employs different technology (piezo vs. electromechanical/magnetic) and operating mode (pulse/slow vs. single tone), requiring control circuit assessment.

Q: What is the acoustic output difference between these two buzzers?

A: The AI-3629-P-30V-R produces 100dB @ 30V at 10cm, while the AI-4329-P-SP28-R produces 88dB @ 12V at 10cm. This represents a 12dB reduction in sound pressure level. Applications with specific acoustic requirements must account for this difference.

Q: Are the physical dimensions compatible for panel mounting?

A: Both components are panel mount with top port location. However, the AI-4329-P-SP28-R has a larger diameter of 1.693" (43.00mm) compared to 1.417" (36.00mm) for the AI-3629-P-30V-R. Panel cutout dimensions must be verified for the substitute.

Q: What is the connector compatibility between these parts?

A: Both components use screw terminal with quick connect tab termination. The main part uses 0.248" (6.30mm) tabs, while the substitute uses 0.256" (6.50mm) tabs. Connector compatibility with existing wiring harnesses must be verified.

Q: What is the current consumption difference?

A: The AI-3629-P-30V-R draws 60mA at rated voltage, while the AI-4329-P-SP28-R draws 6mA at rated voltage. The substitute consumes significantly less power, which may affect power supply sizing and thermal management considerations.

Q: Is the substitute RoHS compliant?

A: Yes. The AI-4329-P-SP28-R is ROHS3 compliant. RoHS compliance status for the main part is not specified in the available data.

Q: What is the operating temperature range for both components?

A: Both the AI-3629-P-30V-R and AI-4329-P-SP28-R operate across the identical temperature range of -20°C to 60°C.
