AT-15 Equivalent & Substitute Parts

Part Overview

The AT-15 is a piezoelectric buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven panel mount component with a 30mm flange and wire lead termination. Operating at 4.5kHz, this device is classified as obsolete product status. Due to its obsolete classification and limited availability for new designs, identifying equivalent substitute parts with compatible electrical and mechanical characteristics is necessary for system continuity and component sourcing.

Substitute Part Grouping Explanation

The AT-3045-TF-LW110-R qualifies as a direct substitute based on the following critical parameters:

• Manufacturer: Identical (PUI Audio, Inc.)
• Series: Identical (AT series)
• Technology: Identical (Piezo)
• Driver Circuitry: Identical (Transducer, Externally Driven)
• Frequency: Identical (4.5kHz)
• Mounting Type: Identical (Panel Mount, Flange)
• Size / Dimension: Identical (1.181" Dia / 30.00mm)
• Termination: Identical (Wire Leads)

The AT-3045-TF-LW110-R maintains mechanical and functional compatibility while providing active product status and enhanced compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AT-3045-TF-LW110-R is the direct substitute for the obsolete AT-15. Selection is based on:

• Product Status Alignment: The AT-3045-TF-LW110-R maintains active product status, ensuring long-term availability and supply chain continuity.
• Mechanical Compatibility: Identical mounting configuration (Panel Mount, Flange), dimensional specifications (30mm diameter), and termination method (Wire Leads) ensure direct mechanical interchange.
• Functional Equivalence: Identical frequency (4.5kHz), technology (Piezo), and driver circuitry (Externally Driven Transducer) maintain functional performance.
• Compliance Enhancement: The substitute provides ROHS3 compliance, addressing modern regulatory requirements where the original AT-15 does not.

Frequently Asked Questions (FAQ)

Q: Can the AT-3045-TF-LW110-R directly replace the AT-15 in existing designs?

A: Yes. Both components share identical mounting type (Panel Mount, Flange), size (30mm diameter), frequency (4.5kHz), technology (Piezo), and termination (Wire Leads). The maximum seated height difference (0.201" vs 0.220") is within typical mechanical tolerance for panel mount applications.

Q: What are the key differences between AT-15 and AT-3045-TF-LW110-R?

A: The AT-3045-TF-LW110-R provides specified electrical parameters (10V rated, 1-50V range, 11mA supply current, 97dB SPL), operating temperature range (-30°C to 85°C), and ROHS3 compliance. The AT-15 does not specify these parameters.

Q: Why is the AT-15 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The AT-3045-TF-LW110-R maintains active status and is the recommended alternative for new designs and component replenishment.

Q: Are there packaging differences between these parts?

A: The AT-15 packaging is listed as unspecified. The AT-3045-TF-LW110-R is supplied in Bulk packaging.

Q: Does the AT-3045-TF-LW110-R meet modern compliance standards?

A: Yes. The AT-3045-TF-LW110-R is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The AT-15 is RoHS non-compliant.
