Key Parameters

Substitute Part Grouping Explanation

The AS03508CO-2-R qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Impedance: 8 Ohms (exact match)
• Power rating: 1 W rated, 2 W maximum (exact match)
• Frequency range: 500 Hz ~ 20 kHz (exact match)
• Sound pressure level: 84 dBA at 1W/500mm (exact match)
• Physical dimensions: 35.00mm x 20.00mm with 8.00mm seated height (exact match)
• Port location: Top (exact match)
• Termination type: Solder Eyelet(s) (exact match)
• Material composition: Cloth cone, Nd-Fe-B magnet (exact match)

The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The AS03508CO-2-R is the appropriate selection for new designs and ongoing procurement. This part maintains identical electrical performance and mechanical compatibility while offering the following advantages:

• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance satisfies current regulatory requirements for restricted substances
• Tray packaging provides standard handling and storage configuration
• All electrical parameters, frequency response, impedance, power ratings, and physical dimensions remain unchanged from the obsolete AS03508CO-2

For existing designs currently using AS03508CO-2, direct substitution with AS03508CO-2-R requires no circuit modifications or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can AS03508CO-2-R be used as a direct replacement for AS03508CO-2?

A: Yes. Both parts share identical impedance (8 Ohms), power ratings (1 W rated, 2 W maximum), frequency response (500 Hz ~ 20 kHz), efficiency (84 dBA), physical dimensions (35.00mm x 20.00mm), and termination type (Solder Eyelet). No circuit or mechanical modifications are required.

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

A: The AS03508CO-2-R is the active production equivalent of the obsolete AS03508CO-2. The substitute part includes ROHS3 compliance and standard tray packaging, while maintaining identical electrical and mechanical specifications.

Q: Are there any compatibility concerns with packaging differences?

A: The AS03508CO-2-R is supplied in tray packaging, which is standard for component handling and storage. This does not affect electrical performance or mechanical fit in the application.

Q: Does the RoHS compliance change affect circuit design?

A: No. ROHS3 compliance reflects manufacturing process changes to restrict hazardous substances. Electrical performance and circuit behavior remain identical to the non-compliant version.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical solder eyelet termination and physical dimensions ensure direct mechanical and electrical compatibility without PCB redesign.
