• Series: Both belong to the AI series
• Driver Circuitry: Both feature internally driven indicator configuration
• Input Type: Both operate on DC input
• Rated Voltage: Both are rated at 12V
• Frequency: Both operate at 400Hz
• Technology: Both use electromechanical/magnetic technology
• Mounting Type: Both feature panel mount with flange configuration
• Termination: Both use wire leads
• Physical Dimensions: Both share identical footprint (32.00mm x 17.00mm) and height (16.05mm)

The substitute part provides enhanced specifications including defined operating temperature range, current supply rating, and sound pressure level, while maintaining full mechanical and electrical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The AI-2304-TF-LW120-12V-R is the direct equivalent for the obsolete AI-222. Both parts share identical electrical ratings, mechanical form factors, and mounting specifications, ensuring drop-in compatibility in existing designs.

The substitute part offers improved regulatory compliance with ROHS3 certification, whereas the original AI-222 is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the AI-2304-TF-LW120-12V-R provides compliant operation while maintaining functional equivalence.

Both parts retain REACH Unaffected status and EAR99 export classification. The substitute part provides documented operating parameters including temperature range (-20°C ~ 60°C), current consumption (30mA), and acoustic output (89dB @ 12V, 10cm), enabling more precise system design and validation.

Frequently Asked Questions (FAQ)

Q: Can the AI-2304-TF-LW120-12V-R directly replace the AI-222 in existing assemblies?

A: Yes. Both parts share identical mounting type (panel mount flange), termination (wire leads), physical dimensions (32.00mm x 17.00mm), and electrical specifications (12V DC, 400Hz, internally driven). No circuit modifications or mechanical redesign is required.

Q: What is the primary difference between these two parts?

A: The AI-2304-TF-LW120-12V-R provides fully specified operating parameters including voltage range (8-16V), current consumption (30mA), sound pressure level (89dB @ 12V, 10cm), and operating temperature range (-20°C ~ 60°C). The original AI-222 lacks these detailed specifications. Additionally, the substitute part is ROHS3 compliant while the AI-222 is RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: The AI-222 packaging is listed as unspecified. The AI-2304-TF-LW120-12V-R is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the substitute part operate within the same voltage range as the original?

A: The AI-222 is rated at 12V with no specified voltage range. The AI-2304-TF-LW120-12V-R operates across 8-16V, providing broader voltage tolerance. Both parts are rated for 12V nominal operation, ensuring compatibility in 12V DC systems.

Q: What compliance certifications apply to the substitute part?

A: The AI-2304-TF-LW120-12V-R is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification. Verify compliance requirements for your specific application and regulatory jurisdiction.
