Frequently Asked Questions (FAQ)

Q: Can the AI-4328-P-C120-R directly replace the AI-382-HT in existing applications?

A: Yes. Both parts share identical core electrical specifications: 110V rated voltage, 2.8kHz frequency, AC/DC input capability, and internally driven piezo technology. Physical mounting is panel mount for both configurations.

Q: What are the key differences between these parts?

A: The AI-4328-P-C120-R provides additional documented specifications including operating temperature range (-30°C to 85°C), current draw (17mA), sound pressure level (98dB @ 110V, 10cm), and defined termination type (Screw Terminal with Quick Connect Tab). The substitute also achieves ROHS3 compliance versus the non-compliant status of the original part.

Q: Are there packaging considerations for substitution?

A: The AI-382-HT packaging is not specified in available documentation. The AI-4328-P-C120-R is supplied in bulk packaging with defined dimensions: 1.673" diameter (42.50mm) and 1.319" maximum seated height (34.60mm). Physical verification against original equipment specifications is necessary to confirm mechanical compatibility.

Q: Does the voltage range difference affect substitution suitability?

A: The AI-4328-P-C120-R operates across 30 ~ 120V range while the AI-382-HT voltage range is not specified. At the common 110V operating point, both parts function identically. The extended range of the substitute provides additional operational flexibility without compromising compatibility at the rated voltage.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts share identical ECCN (EAR99), HTSUS (8531.80.9041), and REACH status classifications. The AI-4328-P-C120-R achieves superior RoHS compliance (ROHS3 versus non-compliant), which may be required for new system designs or regional market requirements.
