Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS01508AO-SC-R is determined by strict alignment of the following critical parameters:

• Impedance: 8 Ohms (electrical compatibility requirement)
• Power Rating: 700 mW rated, 1 W maximum (power handling capacity)
• Port Location: Top (mechanical mounting constraint)
• Shape: Rectangular (form factor requirement)
• Physical Dimensions: 15.00mm × 11.00mm length and width (PCB layout constraint)
• Maximum Seated Height: 3.90mm (clearance requirement)
• Termination Type: Spring Type (connection interface)
• Magnet Material: Nd-Fe-B (performance consistency)

The AS01508MO-SC11-R meets all critical substitution criteria, maintaining identical electrical specifications, mechanical form factor, and interface requirements while offering improved efficiency characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AS01508MO-SC11-R is the direct substitute for the AS01508AO-SC-R based on the following engineering criteria:

All critical electrical and mechanical parameters are identical, ensuring direct compatibility in existing circuit designs and mechanical assemblies. The substitute maintains the same impedance, power rating, port configuration, and physical dimensions required for PCB integration and enclosure mounting.

Both components are ROHS3 compliant and manufactured by the same supplier, ensuring consistent quality and regulatory compliance. The AS01508MO-SC11-R carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete AS01508AO-SC-R.

The substitute exhibits improved efficiency at 89.00 dBA compared to 84.00 dBA in the original part, representing a measurable performance enhancement while maintaining all interface and form factor requirements.

Frequently Asked Questions (FAQ)

Q: Can AS01508MO-SC11-R be used as a direct replacement for AS01508AO-SC-R in existing designs?

A: Yes. Both components share identical impedance (8 Ohms), power ratings (700 mW rated, 1 W maximum), port location (top), shape (rectangular), physical dimensions (15.00mm × 11.00mm), seated height (3.90mm), and spring-type termination. No circuit modifications or mechanical redesign is required.

Q: What are the key differences between these two parts?

A: The primary differences are product status and efficiency. The AS01508MO-SC11-R is an active product with 89.00 dBA efficiency, while the AS01508AO-SC-R is obsolete with 84.00 dBA efficiency. The substitute also has a slightly higher self-resonant frequency (600 Hz versus 550 Hz) and uses PEI cone material instead of polyester/PET.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8518.29.8000) classifications. The AS01508MO-SC11-R includes additional REACH Unaffected status documentation.

Q: What packaging is available for the substitute part?

A: The AS01508MO-SC11-R is supplied in Tray packaging, compared to the original part's standard packaging configuration.

Q: Does the frequency range difference affect compatibility?

A: The AS01508MO-SC11-R operates across 600 Hz to 20 kHz versus 550 Hz to 20 kHz for the original part. This 50 Hz difference in lower frequency response does not affect electrical or mechanical compatibility and represents a minor specification variation within the same product category.
