AS5008 Speaker - Equivalent & Substitute Parts

Part Overview

The AS5008 is an 8 Ohm general purpose speaker rated at 100 mW with a frequency range of 500 Hz to 4.5 kHz and a sound pressure level of 91 dBA. This component features a top-mounted round port, paper cone, and neodymium-iron-boron magnet construction with solder eyelet termination. The AS5008 is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The AS05008PR-R qualifies as a direct substitute for the AS5008 based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical impedance (8 Ohms), rated power (100 mW), and maximum power (200 mW) specifications
• Acoustic Performance: Both operate within the same frequency range (500 Hz ~ 4.5 kHz) and self-resonant frequency (500 Hz)
• Mechanical Compatibility: Both feature identical diameter (1.969" / 50.00 mm), round shape, top port location, and solder eyelet termination
• Material Consistency: Both use paper cone and neodymium-iron-boron magnet construction

The primary difference is the efficiency rating (91 dBA vs. 81 dBA) and physical height (0.354" vs. 0.394"), with the substitute offering improved RoHS3 compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AS05008PR-R is the direct equivalent for the obsolete AS5008. Selection of the substitute is supported by:

• Product Status: The AS05008PR-R maintains active product status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute achieves ROHS3 compliance, meeting current environmental and regulatory requirements that the original part does not satisfy
• Electrical and Mechanical Equivalence: All critical electrical parameters (impedance, power ratings, frequency response) and mechanical dimensions remain identical, ensuring drop-in compatibility in existing circuit designs
• Height Consideration: The substitute exhibits a 0.040" (1.00 mm) increase in seated height, which must be evaluated against available PCB or enclosure clearance in the target application

Frequently Asked Questions (FAQ)

Q: Can the AS05008PR-R be used as a direct replacement for the AS5008 in existing designs?

A: Yes. The AS05008PR-R maintains identical electrical specifications (8 Ohms, 100 mW rated power, 500 Hz ~ 4.5 kHz frequency range) and mechanical dimensions (50.00 mm diameter, top port, round shape, solder eyelet termination). The 1.00 mm increase in seated height must be verified against available clearance in the target assembly.

Q: What is the significance of the efficiency rating difference between these parts?

A: The AS5008 is rated at 91 dBA while the AS05008PR-R is rated at 81 dBA. These measurements were conducted under different testing conditions (1W/500mm vs. 100mW/500mm). Both parts operate within the same frequency range and impedance, and the difference reflects measurement methodology rather than fundamental acoustic incompatibility.

Q: Why is RoHS compliance important for this substitution?

A: RoHS3 compliance ensures the substitute part meets current environmental regulations for restricted substances. The original AS5008 is RoHS non-compliant, making the AS05008PR-R necessary for applications subject to regulatory requirements or customer specifications mandating RoHS compliance.

Q: Are there packaging differences between these parts?

A: The AS5008 packaging is unspecified in available documentation. The AS05008PR-R is supplied in Tray packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: What is the impact of the different efficiency testing conditions?

A: The AS5008 was tested at 1W/500mm while the AS05008PR-R was tested at 100mW/500mm. This difference in test methodology explains the dBA rating variance. Both parts are rated for identical maximum power (200 mW) and operate within the same acoustic frequency range.
