Key Parameters

Substitute Part Grouping Explanation

The AT-1228-TT-R qualifies as a direct substitute for the AT-10SI based on the following alignment of core parameters:

• Same manufacturer: PUI Audio, Inc.
• Same series: AT
• Identical technology: Electromechanical/Magnetic
• Identical driver circuitry: Transducer, Externally Driven
• Identical mounting type: Through Hole
• Identical termination: PC Pins
• Compatible compliance profile: Both are REACH Unaffected

The AT-1228-TT-R is an active product with enhanced specifications including rated voltage (1.5V), defined frequency response (2.8kHz), and documented sound pressure level (85dB @ 1.5V, 10cm), making it suitable for applications requiring the functional characteristics of the obsolete AT-10SI.

Parameter Comparison

Engineering Selection Recommendations

The AT-1228-TT-R is the designated substitute for the obsolete AT-10SI. Selection of this component is based on:

• Functional equivalence: Both components share identical core technology, driver architecture, and mechanical interface specifications
• Product status alignment: The AT-1228-TT-R is an active product with documented specifications, ensuring long-term availability and supply chain continuity
• Compliance improvement: The AT-1228-TT-R achieves ROHS3 compliance, addressing regulatory requirements that may apply to new designs or manufacturing revisions
• Specification documentation: The AT-1228-TT-R provides complete electrical and mechanical parameters, enabling precise circuit design and integration validation

For applications currently using the AT-10SI, direct substitution with the AT-1228-TT-R is supported by the alignment of mounting type, termination style, and transducer technology.

Frequently Asked Questions (FAQ)

Q: Can the AT-1228-TT-R be used as a direct replacement for the AT-10SI?

A: Yes. Both components are externally driven electromechanical magnetic transducers with through-hole PC pin termination from the same manufacturer and series. The AT-1228-TT-R is the active equivalent.

Q: What are the key differences between these components?
