Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS04008CO-2 is determined by matching the following critical electrical and mechanical parameters:

• Impedance: 8 Ohms (electrical interface requirement)
• Power Rating: 1.5 W rated / 3 W maximum (thermal and operational envelope)
• Frequency Range: 200 Hz ~ 20 kHz (acoustic performance specification)
• Self Resonant Frequency: 550 Hz (acoustic characteristic)
• Sound Pressure Level: 84 dBA at 1W/500mm (efficiency specification)
• Physical Dimensions: 1.575" L x 0.787" W x 0.315" H maximum (mechanical fit)
• Port Location: Top (installation orientation)
• Shape: Oval, Rectangular Frame (form factor compatibility)
• Termination: Solder Eyelet(s) (electrical connection method)

The AS04008CO-2-R meets all specified electrical and mechanical parameters, establishing direct substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AS04008CO-2-R is the direct equivalent for the obsolete AS04008CO-2. Both parts are manufactured by PUI Audio, Inc. and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status and regulatory compliance. The AS04008CO-2-R is currently in active production status, whereas the original AS04008CO-2 is obsolete. Additionally, the AS04008CO-2-R carries ROHS3 compliance certification, compared to the non-compliant status of the original part. For applications subject to RoHS regulatory requirements, the AS04008CO-2-R is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can AS04008CO-2-R be used as a direct replacement for AS04008CO-2?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including impedance, power rating, frequency response, efficiency, dimensions, and termination method.

Q: What is the difference between AS04008CO-2 and AS04008CO-2-R?

A: The primary differences are product status and regulatory compliance. The AS04008CO-2-R is in active production and carries ROHS3 compliance certification. The AS04008CO-2 is obsolete and RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: The AS04008CO-2-R is supplied in Tray packaging. The original AS04008CO-2 packaging specification is not defined in the available data.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching impedance (8 Ohms), power rating (1.5 W rated / 3 W maximum), frequency range (200 Hz ~ 20 kHz), self-resonant frequency (550 Hz), efficiency (84 dBA), physical dimensions (1.575" L x 0.787" W x 0.315" H), port location (top), shape (oval rectangular frame), and termination method (solder eyelet).

Q: Is the AS04008CO-2-R suitable for new designs?

A: Yes. The AS04008CO-2-R is in active production status and carries current regulatory compliance certifications, making it appropriate for new design implementations.
