AS06608MR Equivalent & Substitute Parts

Part Overview

The AS06608MR is an 8 Ohm general purpose speaker rated at 500 mW, manufactured by PUI Audio, Inc. This speaker features a top-mounted round port with a 66mm diameter and operates across a frequency range of 380 Hz to 7.5 kHz. The product is currently classified as obsolete, which necessitates identification of equivalent alternatives for ongoing applications and new designs requiring comparable acoustic and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS06608MR is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Impedance (8 Ohms), rated power (500 mW), and maximum power (800 mW) must match exactly to ensure circuit compatibility and prevent damage to driving electronics.
• Acoustic Performance: Frequency range (380 Hz ~ 7.5 kHz), self-resonant frequency (380 Hz), and efficiency rating (84.00 dBA at 1W/1M) must be identical to maintain system performance.
• Mechanical Fit: Diameter (66.00mm), height (12.50mm maximum seated), port location (top), and shape (round) must align with enclosure and PCB mounting requirements.
• Material Composition: Cone material (Polyester/PET) and magnet type (Ferrite) define acoustic characteristics and environmental durability.
• Termination: Solder eyelet termination must be preserved for assembly compatibility.

The AS06608MR-R qualifies as a direct substitute based on complete parameter alignment across all electrical, acoustic, and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AS06608MR-R is the direct equivalent substitute for the obsolete AS06608MR. Both parts maintain identical electrical, acoustic, and mechanical specifications, ensuring drop-in compatibility in existing designs.

The primary distinction between the two parts is product status and regulatory compliance. The AS06608MR-R is classified as active and carries ROHS3 compliance certification, whereas the AS06608MR is obsolete and RoHS non-compliant. For new designs and ongoing production requiring regulatory adherence to RoHS3 standards, the AS06608MR-R is the appropriate selection. The AS06608MR-R is supplied in tray packaging, which differs from the original part's packaging designation.

Frequently Asked Questions (FAQ)

Q: Can the AS06608MR-R be used as a direct replacement for the AS06608MR?

A: Yes. The AS06608MR-R is electrically and mechanically identical to the AS06608MR across all specified parameters, including impedance, power rating, frequency response, efficiency, physical dimensions, and termination type. No circuit modifications are required.

Q: What is the primary reason to transition from AS06608MR to AS06608MR-R?

A: The AS06608MR is classified as obsolete, making long-term availability uncertain. The AS06608MR-R is an active product with confirmed availability. Additionally, the AS06608MR-R meets ROHS3 compliance requirements, whereas the original part does not.

Q: Are there any performance differences between these two speakers?

A: No. Both parts deliver identical acoustic performance with 84.00 dBA efficiency at 1W/1M, operate across 380 Hz to 7.5 kHz, and handle 500 mW rated power with 800 mW maximum power capability.

Q: Does packaging affect compatibility?

A: Packaging does not affect electrical or mechanical compatibility. The AS06608MR-R is supplied in tray packaging, which is a standard distribution format. Packaging selection is determined by procurement and assembly requirements, not functional performance.

Q: What impedance and power specifications must be matched for substitution?

A: For this speaker category, impedance must be exactly 8 Ohms, rated power must be 500 mW, and maximum power must be 800 mW. Deviations in these parameters will result in circuit incompatibility or performance degradation.

Q: Are the physical dimensions identical?

A: Yes. Both speakers have a 66.00mm diameter, 12.50mm maximum seated height, round shape, and top port location. They are mechanically interchangeable in existing enclosures and PCB layouts.
