Substitute Part Grouping Explanation

Substitute parts for the AT-41 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution compatibility are:

• Impedance: 8 Ohms
• Power rating: 150 mW rated / 200 mW maximum
• Frequency response: 500 Hz ~ 20 kHz
• Self-resonant frequency: 1400 Hz
• Sound pressure level: 72 dBA
• Physical dimensions: 1.175" diameter, 0.492" maximum seated height
• Port configuration: Top-mounted round port
• Termination type: PC Pins

The AST-03008MR-R meets all electrical and mechanical specifications of the AT-41, providing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The AST-03008MR-R is the direct substitute for the obsolete AT-41. Both components are manufactured by PUI Audio, Inc. and share identical electrical and mechanical specifications across all critical parameters.

The AST-03008MR-R offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Additionally, the AST-03008MR-R achieves ROHS3 compliance, whereas the AT-41 is non-compliant. For applications subject to RoHS regulatory requirements, the AST-03008MR-R is the appropriate selection.

Both components carry identical REACH and ECCN classifications, indicating equivalent regulatory standing for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the AST-03008MR-R directly replace the AT-41 in existing designs?

A: Yes. The AST-03008MR-R matches all electrical and mechanical parameters of the AT-41, including impedance, power rating, frequency response, physical dimensions, and termination type. Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between these two parts?

A: The AT-41 is classified as obsolete, while the AST-03008MR-R maintains active product status. The AST-03008MR-R also achieves ROHS3 compliance, whereas the AT-41 is non-compliant.

Q: Are there packaging differences between the AT-41 and AST-03008MR-R?

A: The AT-41 is supplied in standard packaging, while the AST-03008MR-R is packaged in trays. Both configurations are suitable for component handling and storage.

Q: Do these speakers have identical acoustic performance?

A: Yes. Both components share identical frequency response (500 Hz ~ 20 kHz), self-resonant frequency (1400 Hz), and sound pressure level (72 dBA), ensuring equivalent acoustic output.

Q: Are there any compliance considerations when switching from AT-41 to AST-03008MR-R?

A: The AST-03008MR-R provides ROHS3 compliance, which may be required for applications subject to RoHS regulations. Both components maintain equivalent REACH and ECCN classifications.
