AI-435 Equivalent & Substitute Parts

Part Overview

The AI-435 is a piezo buzzer manufactured by PUI Audio, Inc., designed as an internally driven indicator with a 12V DC rated voltage and 41.8mm flange panel mount configuration. This component features wire lead termination and is classified as obsolete product status. Due to its obsolete designation, identifying functionally compatible substitute parts is essential for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AI-435 is determined by the following critical parameters:

• Voltage Rating: 12V DC nominal operation
• Mounting Configuration: Panel Mount, Flange type
• Termination Style: Wire Leads
• Physical Envelope: 41.8mm diameter flange
• Driver Type: Internally Driven Indicator
• Technology: Piezo acoustic element

The AI-4228-TF-SP-LW145-R qualifies as a direct substitute based on matching all critical mechanical and electrical interface parameters. Both components share identical voltage ratings, mounting types, termination methods, and physical flange dimensions. The substitute maintains the same series designation (AI) and piezo technology platform, ensuring functional compatibility within existing circuit designs and mechanical assemblies.

Parameter Comparison

Engineering Selection Recommendations

The AI-4228-TF-SP-LW145-R is the qualified substitute for the obsolete AI-435. Selection of this replacement component is based on:

Product Status: The AI-435 is classified as obsolete, making the active-status AI-4228-TF-SP-LW145-R the appropriate long-term solution for procurement and system continuity.

Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the original component is RoHS non-compliant. This upgrade aligns with current environmental and regulatory requirements for electronic component manufacturing and distribution.

Mechanical Compatibility: Both components maintain identical flange diameter (41.8mm), wire lead termination, and panel mount configuration, ensuring direct mechanical interchangeability without enclosure or PCB modifications.

Electrical Interface: Matching 12V DC rated voltage and internally driven indicator circuitry preserve circuit-level compatibility with existing driver electronics and power supply specifications.

Trade-offs: The substitute exhibits a marginal increase in seated height (0.650" versus 0.630"), which remains within typical mechanical tolerance ranges for panel-mounted assemblies. This dimensional variance does not preclude direct substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the AI-4228-TF-SP-LW145-R be used as a direct replacement for the AI-435 in existing designs?

A: Yes. Both components share identical voltage ratings, mounting configurations, flange dimensions, and wire lead termination. The substitute maintains mechanical and electrical interface compatibility without circuit redesign.

Q: What is the significance of the RoHS compliance difference?

A: The AI-435 is RoHS non-compliant, while the AI-4228-TF-SP-LW145-R achieves ROHS3 compliance. For new designs or systems subject to environmental regulations, the compliant substitute is the appropriate selection. Existing systems using the obsolete component may continue operation without modification.

Q: Are there dimensional constraints that would prevent substitution?

A: The seated height increases from 0.630" to 0.650", a difference of 0.020". This variance is negligible for most panel-mount applications and does not affect flange seating or electrical connection integrity.

Q: Why is the AI-435 listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured or actively supported by PUI Audio, Inc. The AI-4228-TF-SP-LW145-R, with active product status, represents the current manufacturing equivalent within the AI series.

Q: Are REACH and ECCN classifications identical between the two parts?

A: Yes. Both components share identical REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent regulatory treatment for export and supply chain purposes.
