AT-17 Equivalent & Substitute Parts

Part Overview

The AT-17 is a through-hole piezo buzzer transducer manufactured by PUI Audio, Inc., designed as an externally driven piezo acoustic component with PC pin termination. This part 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 design support, maintenance, and new production requirements where the original component is unavailable.

Substitute Part Grouping Explanation

The AT-1438-TWT-R qualifies as a direct substitute for the AT-17 based on the following alignment of core 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, indicating compatibility within the established component lineage
• Technology: Both utilize piezo transducer technology with external drive circuitry
• Mounting Type: Both are through-hole mounted components
• Termination: Both use PC pin termination, ensuring mechanical and electrical compatibility with existing PCB layouts
• Regulatory Classification: Both share identical ECCN (EAR99) and HTSUS (8531.80.9041) classifications

The AT-1438-TWT-R represents an active production alternative that maintains the fundamental electrical and mechanical interface requirements of the obsolete AT-17.

Parameter Comparison

Engineering Selection Recommendations

The AT-1438-TWT-R is the designated substitute for the obsolete AT-17. Selection of this alternative is based on:

• Product Status Alignment: The AT-1438-TWT-R maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The AT-1438-TWT-R achieves ROHS3 compliance, meeting current environmental and material restriction standards, whereas the AT-17 is RoHS non-compliant
• Interface Compatibility: Identical mounting type (through-hole), termination style (PC pins), and series designation ensure direct PCB layout compatibility
• Manufacturer Consistency: Both components originate from PUI Audio, Inc., maintaining design philosophy and quality standards within the AT series family

For applications requiring the AT-17, the AT-1438-TWT-R provides the appropriate active production equivalent with enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the AT-1438-TWT-R be used as a direct replacement for the AT-17 in existing designs?

A: Yes. Both components share identical mounting type (through-hole), termination (PC pins), and series designation (AT). The AT-1438-TWT-R maintains the same electrical interface requirements and physical footprint compatibility.

Q: What is the primary difference between the AT-17 and AT-1438-TWT-R?

A: The AT-17 is obsolete and RoHS non-compliant, while the AT-1438-TWT-R is in active production and ROHS3 compliant. The AT-1438-TWT-R provides specified electrical parameters (5V rated, 3.8kHz frequency, 80dB SPL) and operating temperature range (-30°C ~ 80°C).

Q: Are there packaging differences between these parts?

A: The AT-17 packaging is not specified. The AT-1438-TWT-R is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the AT-1438-TWT-R meet current regulatory requirements?

A: Yes. The AT-1438-TWT-R is ROHS3 compliant and REACH unaffected, meeting current environmental and material restriction standards. The AT-17 is RoHS non-compliant.

Q: What electrical parameters should be considered when substituting the AT-1438-TWT-R?

A: The AT-1438-TWT-R operates at a rated voltage of 5V with a voltage range of 1 ~ 20V, operates at 3.8kHz, and draws 1mA supply current. Verify these parameters align with your circuit design requirements.
