AT-14 Equivalent & Substitute Parts

Part Overview

The AT-14 is a piezoelectric buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven panel mount component with a 41.8mm flange and wire lead termination. Operating at 3kHz, this device is classified as obsolete and is no longer in active production. Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where this component specification remains relevant.

Key Parameters

Substitute Part Grouping Explanation

The AT-4230-TF-LW135-R qualifies as a direct substitute for the AT-14 based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by PUI Audio, Inc., ensuring design consistency and compatibility within the AT series
• Technology & Driver Circuitry: Both utilize piezoelectric transducer technology with external drive configuration
• Frequency: Both operate at 3kHz, maintaining acoustic performance specifications
• Mounting & Termination: Both feature panel mount flange configuration with wire lead termination
• Physical Dimensions: Both share identical diameter (41.80mm) and compatible height specifications (16.00mm vs. 16.50mm)

The AT-4230-TF-LW135-R represents an active production alternative that maintains functional equivalence while providing enhanced electrical specifications and modern compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The AT-4230-TF-LW135-R is the appropriate substitute for the obsolete AT-14 in applications requiring continued system operation or component replacement. Selection is justified on the following basis:

• Functional Equivalence: Identical frequency response (3kHz), mounting configuration, and termination method ensure direct mechanical and electrical compatibility
• Active Production Status: The AT-4230-TF-LW135-R is in active production, providing supply chain continuity and availability
• Compliance Enhancement: The substitute part achieves ROHS3 compliance, addressing modern regulatory requirements that the AT-14 does not meet
• Regulatory Alignment: Both parts maintain identical ECCN (EAR99) and HTSUS (8531.80.9041) classifications, ensuring consistent export and import compliance

For applications where RoHS compliance is mandatory, the AT-4230-TF-LW135-R is the required selection. For legacy systems where RoHS non-compliance is acceptable, the substitute part remains functionally equivalent and operationally compatible.

Frequently Asked Questions (FAQ)

Q: Can the AT-4230-TF-LW135-R directly replace the AT-14 in existing designs?

A: Yes. Both parts share identical frequency (3kHz), mounting type (panel mount flange), termination method (wire leads), and physical diameter (41.80mm). The height difference (0.630" vs. 0.650") is within typical mechanical tolerance ranges for panel mount applications.

Q: What are the key differences between these parts?

A: The AT-4230-TF-LW135-R provides specified electrical parameters (10V rated, 1-30V operating range, 9mA supply current) and acoustic output (96dB @ 10V, 10cm) that are not documented for the AT-14. The substitute part also achieves ROHS3 compliance, whereas the AT-14 is RoHS non-compliant.

Q: Is the AT-4230-TF-LW135-R suitable for applications originally designed for the AT-14?

A: Yes, provided the application's electrical requirements fall within the AT-4230-TF-LW135-R's specified voltage range (1-30V) and operating temperature range (-30°C to 85°C). The identical frequency and mounting configuration ensure acoustic and mechanical compatibility.

Q: What is the packaging difference between these parts?

A: The AT-14 packaging is listed as "-" (not specified). The AT-4230-TF-LW135-R is supplied in Bulk packaging. This difference does not affect functional compatibility.

Q: Are there any compliance considerations when substituting the AT-14 with the AT-4230-TF-LW135-R?

A: Both parts maintain identical ECCN (EAR99) and HTSUS (8531.80.9041) classifications. The AT-4230-TF-LW135-R's ROHS3 compliance may be required for applications subject to RoHS regulations, making it the preferred choice for modern system designs.
