Parameter Comparison

Engineering Selection Recommendations

The AI-4228-TF-LW140-4-R is the appropriate substitute for the obsolete AI-430. Selection is based on the following factors:

• Product Status: The AI-430 is obsolete, while the AI-4228-TF-LW140-4-R is active and maintains current manufacturing support.
• Compliance: The AI-4228-TF-LW140-4-R achieves ROHS3 compliance, whereas the AI-430 is RoHS non-compliant. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.
• Physical Compatibility: Both parts share identical diameter (41.80mm) and wire lead termination, with a negligible height difference of 0.020" (0.50mm).
• Electrical Compatibility: Both parts operate at 12V rated voltage with DC input and internally driven piezo technology.

The substitute part provides documented operational specifications including frequency (2.8kHz), sound pressure level (95dB @ 12V, 10cm), current draw (7mA), and operating temperature range (-20°C ~ 60°C), enabling precise system integration.

Frequently Asked Questions (FAQ)

Q: Can the AI-4228-TF-LW140-4-R directly replace the AI-430 in existing designs?

A: Yes. Both parts share identical mounting type (panel mount flange), termination method (wire leads), diameter (41.8mm), and rated voltage (12V DC). The height difference of 0.020" is negligible for most panel mount applications.

Q: What is the primary reason for substitution?

A: The AI-430 is obsolete. The AI-4228-TF-LW140-4-R is an active product from the same manufacturer and series, ensuring continued availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Yes. The AI-4228-TF-LW140-4-R is ROHS3 compliant, while the AI-430 is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Q: What are the operational specifications of the substitute part?

A: The AI-4228-TF-LW140-4-R operates at 2.8kHz with a single tone output, produces 95dB SPL at 12V measured 10cm from the device, draws 7mA supply current, and functions across -20°C to 60°C operating temperature range.

Q: Is the voltage range different between the two parts?

A: The AI-430 voltage range is not specified. The AI-4228-TF-LW140-4-R operates across 3V to 18V, providing broader supply voltage tolerance while maintaining 12V as the rated voltage.

Q: Are packaging considerations different?

A: The AI-430 packaging is not specified. The AI-4228-TF-LW140-4-R is supplied in bulk packaging. Both parts use identical wire lead termination and panel mount flange configuration.
