Key Parameters

Substitute Part Grouping Explanation

The AT-1220-TT-3-R qualifies as a direct substitute for the AT-101Z-4 based on the following critical parameters:

• Driver Circuitry: Both components utilize externally driven transducer architecture
• Frequency: Both operate at 2.048kHz
• Technology: Both employ electromechanical/magnetic technology
• Mounting Type: Both use through-hole mounting
• Termination: Both feature PC pin termination
• Manufacturer: Both are manufactured by PUI Audio, Inc., within the AT series

The AT-1220-TT-3-R represents an active product with enhanced specifications, including defined voltage range (1–3V), rated voltage (1.5V), current consumption (10mA), sound pressure level (73dB @ 1.5V, 10cm), and operating temperature range (–20°C to 70°C). These additional specifications provide greater design flexibility and regulatory compliance compared to the obsolete AT-101Z-4.

Parameter Comparison

Engineering Selection Recommendations

The AT-1220-TT-3-R is the designated substitute for the obsolete AT-101Z-4. Selection of this substitute is justified on the following engineering grounds:

• Product Status Alignment: The AT-1220-TT-3-R maintains active product status, ensuring long-term availability and manufacturing support
• Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant, meeting current environmental and regulatory requirements
• Functional Equivalence: Both components share identical driver circuitry, frequency specification, technology platform, and mechanical interface characteristics
• Specification Enhancement: The AT-1220-TT-3-R provides fully defined electrical and thermal parameters, eliminating design ambiguity present in the original part specification

Frequently Asked Questions (FAQ)

Q: Can the AT-1220-TT-3-R be used as a direct replacement for the AT-101Z-4 in existing designs?

A: Yes. Both components share identical driver circuitry, frequency (2.048kHz), technology (electromechanical/magnetic), mounting type (through-hole), and termination (PC pins). The AT-1220-TT-3-R is electrically and mechanically compatible with the AT-101Z-4 footprint and interface requirements.

Q: What are the key differences between these two parts?

A: The AT-101Z-4 is obsolete with unspecified electrical parameters, while the AT-1220-TT-3-R is an active product with fully defined voltage range (1–3V), rated voltage (1.5V), current consumption (10mA), sound pressure level (73dB @ 1.5V, 10cm), and operating temperature range (–20°C to 70°C). Additionally, the AT-1220-TT-3-R achieves ROHS3 compliance.

Q: Are there any packaging differences between the AT-101Z-4 and AT-1220-TT-3-R?

A: The AT-1220-TT-3-R is supplied in tray packaging. The AT-101Z-4 packaging specification is not provided. Both components use identical through-hole PC pin termination and are compatible with standard PCB assembly processes.

Q: What is the physical size of the AT-1220-TT-3-R?

A: The AT-1220-TT-3-R has a diameter of 0.472 inches (12.00mm) and a maximum seated height of 0.236 inches (6.00mm), making it suitable for space-constrained applications requiring compact buzzer integration.

Q: Does the AT-1220-TT-3-R meet current environmental standards?

A: Yes. The AT-1220-TT-3-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
