Key Parameters

Substitute Part Grouping Explanation

The AS01508MR-6-R qualifies as a direct substitute for the AS01508MR-R based on the following critical parameters:

• Impedance: 8 Ohms (identical)
• Power Rating: 1.2 W rated, 1.8 W maximum (identical)
• Efficiency: 88.00 dBA (identical)
• Physical Dimensions: 0.591" Dia (15.00mm), 0.173" (4.40mm) height (identical)
• Port Location: Top (identical)
• Shape: Round (identical)
• Termination: Solder Pads (identical)
• Material Composition: Polyester PET cone, Nd-Fe-B magnet (identical)

The substitute part extends the frequency range to 900 Hz ~ 20 kHz, providing broader audio spectrum coverage while maintaining all electrical and mechanical compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

The AS01508MR-6-R is the appropriate substitute for the obsolete AS01508MR-R. The substitute maintains full electrical and mechanical compatibility across all critical parameters: impedance, power ratings, efficiency, physical dimensions, and termination method. The extended frequency response (900 Hz ~ 20 kHz versus 900 Hz ~ 12 kHz) represents an enhancement rather than a deviation from the original specification.

The AS01508MR-6-R carries Active product status, ensuring ongoing availability and supply chain stability. Both parts maintain identical REACH and ECCN compliance classifications. The substitute is available in Tray packaging with significantly higher inventory levels (13,580 pcs versus 974 pcs), supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can AS01508MR-6-R be used as a direct replacement for AS01508MR-R in existing designs?

A: Yes. The substitute maintains identical impedance (8 Ohms), power ratings (1.2 W rated, 1.8 W maximum), efficiency (88.00 dBA), physical dimensions (0.591" diameter, 0.173" height), and termination method (solder pads). No circuit modifications are required.

Q: What is the difference between the two parts?

A: The primary difference is frequency range. AS01508MR-R operates from 900 Hz to 12 kHz, while AS01508MR-6-R extends to 20 kHz. Both maintain identical self-resonant frequency (900 Hz) and acoustic efficiency. AS01508MR-6-R is Active status; AS01508MR-R is Obsolete.

Q: Are there packaging differences?

A: AS01508MR-R packaging is listed as dash (-), indicating standard packaging. AS01508MR-6-R is supplied in Tray packaging. Both use identical solder pad termination suitable for automated assembly.

Q: Do compliance certifications differ?

A: No. Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification. Both are subject to HTSUS code 8518.29.8000.

Q: Why is AS01508MR-R obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. AS01508MR-6-R provides equivalent functionality with extended frequency response and Active status, making it the recommended path for new designs and ongoing production support.
