AT-130 Equivalent & Substitute Parts

Part Overview

The AT-130 is a 13mm piezoelectric buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven piezo device operating at 4.8kHz with custom wire leads. This component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The AT-1348-TF-LW90-R qualifies as a direct substitute for the AT-130 based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by PUI Audio, Inc., ensuring design and quality consistency within the same product family
• Series: Both belong to the AT series
• Technology: Both utilize piezoelectric transducer technology
• Driver Circuitry: Both are externally driven piezo transducers
• Frequency: Both operate at 4.8kHz, ensuring functional compatibility in frequency-dependent applications
• Physical Dimensions: Both share identical 0.512" diameter (13.00mm) and 0.098" (2.50mm) maximum seated height, confirming mechanical interchangeability
• Termination: Both feature custom wire leads
• Mounting Type: Both use custom mounting configurations

The AT-1348-TF-LW90-R provides additional specified parameters (rated voltage, current supply, SPL rating, and operating temperature range) that were not documented for the AT-130, making it a more fully characterized alternative.

Engineering Selection Recommendations

The AT-1348-TF-LW90-R is the designated substitute for the obsolete AT-130. Selection of this part is based on:

• Product Status Alignment: The AT-1348-TF-LW90-R maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the AT-130 is RoHS non-compliant. Systems requiring RoHS compliance must transition to the AT-1348-TF-LW90-R
• Mechanical Compatibility: Identical physical dimensions (13mm diameter, 2.5mm height) and wire lead termination enable direct mechanical substitution without PCB redesign
• Functional Equivalence: Matching frequency (4.8kHz), technology (piezo), and driver circuitry (externally driven transducer) ensure functional compatibility in existing applications
• Electrical Characterization: The AT-1348-TF-LW90-R provides complete electrical specifications (10V rated, 1-30V operating range, 5mA supply current, 80dB SPL), enabling precise circuit design validation

Frequently Asked Questions (FAQ)

Q: Can the AT-1348-TF-LW90-R directly replace the AT-130 without circuit modifications?

A: Yes. Both parts share identical frequency (4.8kHz), physical dimensions (13mm diameter, 2.5mm height), and externally driven piezo transducer architecture. The AT-1348-TF-LW90-R operates within a 1-30V range, providing flexibility for existing drive circuits. Verify that your current drive voltage falls within this range.

Q: What is the primary reason for substituting the AT-130?

A: The AT-130 is classified as obsolete and no longer manufactured. The AT-1348-TF-LW90-R is the active production equivalent from the same manufacturer and series, ensuring continued availability and supply chain reliability.

Q: Does the AT-1348-TF-LW90-R meet RoHS requirements?

A: Yes. The AT-1348-TF-LW90-R is ROHS3 compliant, whereas the AT-130 is RoHS non-compliant. Systems subject to RoHS regulations must transition to the AT-1348-TF-LW90-R.

Q: Are the wire lead configurations identical between the two parts?

A: Both parts feature custom wire leads as their termination method. Confirm wire gauge, length, and connection points with the manufacturer datasheet to ensure compatibility with your specific application.

Q: What is the operating temperature range for the substitute part?

A: The AT-1348-TF-LW90-R operates from -20°C to 70°C. If your application requires operation outside this range, consult the manufacturer for alternative options.

Q: Is the 4.8kHz frequency specification identical for both parts?

A: Yes. Both the AT-130 and AT-1348-TF-LW90-R operate at 4.8kHz, ensuring frequency-dependent circuit compatibility.
