AI-3135 Piezo Buzzer Equivalent & Substitute Parts

Part Overview

The AI-3135 is an internally driven piezo buzzer rated at 9V with a 4.6kHz operating frequency, designed for panel mount applications with flange termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The substitute part AI-3135-TF-LW100-R provides functional equivalence with enhanced specifications and active product status.

Key Parameters

Substitute Part Grouping Explanation

The AI-3135-TF-LW100-R qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (PUI Audio, Inc.) and series (AI)
• Matching rated voltage (9V) and operating frequency (4.6kHz)
• Identical driver circuitry (Indicator, Internally Driven) and input type (DC)
• Identical technology (Piezo) and mounting configuration (Panel Mount, Flange)
• Identical port location (Top)
• Same ECCN and HTSUS classifications

The substitute part provides enhanced specifications including active product status, RoHS3 compliance, expanded voltage range (3–20V), specified current draw (8mA), quantified sound pressure level (105dB @ 9V, 10cm), operating temperature range (−20°C to 60°C), and defined physical dimensions (31mm diameter, 14.50mm height).

Parameter Comparison

Engineering Selection Recommendations

The AI-3135-TF-LW100-R is the appropriate substitute for the obsolete AI-3135 based on functional equivalence across all critical electrical and mechanical parameters. The substitute part maintains identical core specifications while providing enhanced compliance status (RoHS3 Compliant versus RoHS non-compliant) and active product availability. Both parts share identical ECCN (EAR99) and HTSUS (8531.80.9041) classifications, confirming regulatory equivalence. The substitute's expanded voltage range (3–20V) and specified performance metrics (8mA current draw, 105dB SPL) provide additional design flexibility without compromising the 9V nominal operation required by existing applications.

Frequently Asked Questions (FAQ)

Q: Can AI-3135-TF-LW100-R directly replace AI-3135 in existing designs?

A: Yes. Both parts share identical rated voltage (9V), frequency (4.6kHz), driver circuitry, input type (DC), technology (Piezo), and mounting configuration (Panel Mount, Flange with top port location). The substitute maintains functional equivalence for all critical parameters.

Q: What are the key differences between these parts?

A: The substitute part (AI-3135-TF-LW100-R) provides enhanced specifications including active product status, RoHS3 compliance, expanded voltage range (3–20V), specified current draw (8mA), quantified sound pressure level (105dB @ 9V, 10cm), operating temperature range (−20°C to 60°C), and defined physical dimensions. The original part (AI-3135) is obsolete with limited specifications documented.

Q: Are there compliance considerations for substitution?

A: The substitute part is RoHS3 compliant, whereas the original is RoHS non-compliant. Both parts maintain identical ECCN and HTSUS classifications. If RoHS compliance is required for new applications, the substitute part satisfies this requirement.

Q: What is the physical compatibility between these parts?

A: Both parts use identical mounting types (Panel Mount, Flange) with top port location. The substitute specifies 31mm diameter and 14.50mm maximum seated height. Verify mechanical fit within your specific panel mount application.

Q: Is the substitute part available in the same packaging?

A: The substitute part (AI-3135-TF-LW100-R) is supplied in Tray packaging with 1119 pieces in current stock, whereas the original part is supplied in unspecified packaging with 820 pieces in stock. Both are new original inventory.
