Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics identical between AI-4228-P-C120 and AI-4228-P-C120-R?

A: Yes. Both parts operate at 110V rated voltage with 30 ~ 120V operating range, accept AC/DC input, produce 2.8kHz output at 92dB SPL, and consume 20mA supply current.

Q: What is the physical difference between these parts?

A: The maximum seated height differs by 0.019" (0.50mm): AI-4228-P-C120 measures 1.280" (32.50mm) while AI-4228-P-C120-R measures 1.299" (33.00mm). This variance is within typical mechanical tolerances for panel mount applications.

Q: Does the substitute part fit existing panel cutouts?

A: Yes. Both parts share identical diameter specifications of 1.673" (42.50mm) and use the same termination configuration. The minimal height difference does not affect panel mounting compatibility.

Q: What compliance improvements does the substitute offer?

A: The AI-4228-P-C120-R is ROHS3 compliant and carries cUL/UL certifications, whereas the original part is RoHS non-compliant with no listed approval agencies.

Q: Can I use AI-4228-P-C120-R as a direct replacement in existing designs?

A: Yes. Electrical performance, mechanical mounting, and termination are identical. The substitute is a direct replacement suitable for new production and field service applications.
