Substitute Part Grouping Explanation

The AI-4228-P-C18-R serves as a direct substitute for the AI-380H based on the following alignment criteria:

Matching Parameters:

• Manufacturer: PUI Audio, Inc. (same manufacturer ensures design compatibility)
• Series: AI (same product family)
• Voltage - Rated: 12 V (identical operating voltage)
• Technology: Piezo (same acoustic technology)
• Driver Circuitry: Indicator, Internally Driven (identical circuit configuration)
• Input Type: DC (same power input type)
• Mounting Type: Panel Mount (identical mechanical mounting)
• Termination: Screw Terminal, Quick Connect Tab - 0.256" (6.50mm) (identical connector interface)
• Size / Dimension: 1.673" Dia (42.50mm) (identical footprint)

The AI-4228-P-C18-R is an active product, whereas the AI-380H is obsolete, making it the appropriate replacement for new designs and system maintenance.

Parameter Comparison

Engineering Selection Recommendations

The AI-4228-P-C18-R is the appropriate substitute for the obsolete AI-380H. Key advantages include:

• Product Status: The AI-4228-P-C18-R is an active product with ongoing manufacturer support, whereas the AI-380H is obsolete and subject to discontinuation.
• Compliance: The AI-4228-P-C18-R meets ROHS3 compliance standards, compared to the non-compliant status of the AI-380H.
• Certifications: The AI-4228-P-C18-R carries cUL and UL approvals, providing additional regulatory validation.
• Mechanical Compatibility: Height difference of 0.019" (0.50mm) between seated positions is negligible for panel-mount applications and does not affect form factor compatibility.
• Electrical Compatibility: Identical rated voltage, termination interface, and mounting configuration ensure direct replacement capability.

Frequently Asked Questions (FAQ)

Q: Can the AI-4228-P-C18-R directly replace the AI-380H in existing designs?

A: Yes. Both components share identical rated voltage (12V), mounting type (panel mount), termination configuration (screw terminal with quick connect tab), and physical footprint (42.5mm diameter). The maximum seated height difference of 0.019" (0.50mm) does not affect panel-mount compatibility.

Q: What is the significance of the AI-380H being obsolete?

A: Obsolete status indicates the manufacturer no longer produces this component. The AI-4228-P-C18-R, as an active product from the same manufacturer and series, is the designated replacement for continued system support and new implementations.

Q: Are there compliance differences between these parts?

A: Yes. The AI-4228-P-C18-R is ROHS3 compliant and carries cUL and UL certifications, whereas the AI-380H is RoHS non-compliant with no specified approval agencies. For applications requiring regulatory compliance, the AI-4228-P-C18-R is the appropriate choice.

Q: What additional performance data is available for the AI-4228-P-C18-R?

A: The AI-4228-P-C18-R provides specified operating parameters including frequency (2.9kHz), sound pressure level (108dB @ 12V, 10cm), current draw (16mA), operating temperature range (-30°C ~ 85°C), and voltage range (7 ~ 18V). The AI-380H does not include these specifications.

Q: Are the termination interfaces identical?

A: Yes. Both components use screw terminal and quick connect tab termination with 0.256" (6.50mm) spacing, ensuring direct electrical and mechanical compatibility without adapter requirements.
