Key Parameters

Substitute Part Grouping Explanation

The AI-4219-P-C28-R qualifies as a direct substitute based on the following critical parameters:

• Identical rated voltage (12V DC)
• Identical frequency output (1.9kHz)
• Identical sound pressure level (81dB @ 12V, 10cm)
• Identical current supply requirement (8mA)
• Identical mounting type (Panel Mount)
• Identical physical diameter (1.673" / 42.50mm)
• Identical operating temperature range (-30°C ~ 85°C)
• Identical termination style (Screw Terminal, Quick Connect Tab)
• Same manufacturer (PUI Audio, Inc.)
• Same series designation (AI)

The substitute part differs only in product status (Active vs. Obsolete), packaging format (Bulk), voltage range capability (6~28V vs. unspecified), height dimension (1.299" vs. 1.280"), and compliance certifications (ROHS3 Compliant and cUL/UL approved vs. non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The AI-4219-P-C28-R is the direct equivalent for the obsolete AI-4219-P-C28. Selection of the substitute part is justified by:

• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance meeting current environmental and regulatory requirements
• cUL and UL certifications providing third-party safety validation
• Expanded voltage range (6~28V) offering greater operational flexibility while maintaining 12V rated performance
• Negligible height difference (0.019") that does not impact mechanical fit in standard panel mount applications
• Identical electrical and acoustic performance at rated 12V operation

The substitute part maintains full functional and mechanical compatibility with the original specification while providing improved compliance posture and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the AI-4219-P-C28-R replace the AI-4219-P-C28 in existing designs?

A: Yes. The substitute part is electrically and mechanically identical at the 12V rated operating point. All critical parameters including frequency, sound pressure level, current draw, mounting configuration, and termination style are unchanged.

Q: What is the significance of the voltage range difference (6~28V vs. unspecified)?

A: The AI-4219-P-C28-R specifies a 6~28V operating range, indicating the component functions across this voltage window. The original part's voltage range was not specified in available documentation. At the 12V rated condition, both parts perform identically.

Q: Does the 0.019" height difference affect panel mounting?

A: No. The height difference (1.299" vs. 1.280") is within typical mechanical tolerances for panel-mount applications and does not impact fit or function in standard enclosure designs.

Q: Why is RoHS3 compliance important for this substitution?

A: RoHS3 compliance indicates the substitute part meets current environmental and hazardous substance restrictions. This is relevant for new designs, regulatory compliance, and long-term supply chain viability.

Q: Are the cUL and UL certifications on the substitute part significant?

A: Yes. These third-party certifications validate safety performance and are often required for applications in regulated industries or markets. The original part's certification status was not documented.

Q: What is the packaging difference between these parts?

A: The AI-4219-P-C28 is listed with unspecified packaging, while the AI-4219-P-C28-R is supplied in Bulk packaging. This affects order quantities and handling but not component performance or compatibility.
