Key Parameters

Substitute Part Grouping Explanation

The AS03008MR-R qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters that must match exactly:

• Impedance: 8 Ohms
• Power rating: 500 mW rated / 1 W maximum
• Frequency range: 650 Hz ~ 15 kHz
• Self-resonant frequency: 650 Hz
• Efficiency: 82 dB SPL
• Physical dimensions: 1.181" diameter (30.00mm), 0.189" maximum seated height
• Port location: Top
• Shape: Round
• Termination: Solder Pads
• Material composition: Polyester cone, Nd-Fe-B magnet

Parameter Comparison

Engineering Selection Recommendations

The AS03008MR-R is the direct equivalent for the obsolete AS03008MR. Both parts are manufactured by PUI Audio, Inc., and share identical electrical performance and mechanical specifications. The primary distinction is product status and regulatory compliance. The AS03008MR-R is currently in active production with ROHS3 compliance certification, whereas the AS03008MR is obsolete and RoHS non-compliant. For new designs or production continuity, the AS03008MR-R is the appropriate selection. The AS03008MR-R is supplied in Tray packaging, providing standard handling and storage conditions for production environments.

Frequently Asked Questions (FAQ)

Q: Can AS03008MR-R replace AS03008MR in existing designs? A: Yes. The AS03008MR-R is electrically and mechanically identical to the AS03008MR. All electrical parameters, physical dimensions, and performance characteristics are equivalent. Direct substitution is possible without circuit or mechanical redesign.

Q: What is the difference between AS03008MR and AS03008MR-R? A: The parts are functionally identical. The AS03008MR-R differs in product status (active vs. obsolete), RoHS compliance (ROHS3 compliant vs. non-compliant), and packaging format (Tray vs. unspecified). The "-R" designation indicates the active production variant.

Q: Are there any compatibility concerns with the packaging change? A: The AS03008MR-R is supplied in Tray packaging, which is standard for production environments. No compatibility issues exist with the component itself. Tray packaging provides appropriate protection and handling for solder pad termination.

Q: What are the critical parameters for substitution? A: Substitution requires matching impedance (8 Ohms), power rating (500 mW), frequency range (650 Hz ~ 15 kHz), efficiency (82 dB SPL), physical dimensions (30mm diameter, 4.80mm height), port location (top), shape (round), and termination type (solder pads).

Q: Is the AS03008MR-R suitable for new production? A: Yes. The AS03008MR-R is in active production status with current RoHS3 compliance certification, making it the appropriate choice for new designs and ongoing production.
