Key Parameters

Substitute Part Grouping Explanation

The AS05008PR-WR-R is classified as a direct manufacturer substitute based on the following substitution criteria:

Maintained Parameters (Compatibility Requirements):

• Impedance: 8 Ohms (electrical interface compatibility)
• Port Location: Top (mechanical mounting compatibility)
• Shape: Round (form factor compatibility)
• Size / Dimension: 1.969" Dia (50.00mm) (physical interchangeability)
• Termination: Solder Eyelet(s) (circuit connection compatibility)
• Material - Magnet: Nd-Fe-B (performance consistency)

Enhanced Parameters (Upgrade Characteristics):

• Power - Rated: 1 W (10x increase from 100 mW)
• Frequency Range: 550 Hz ~ 5 kHz (expanded from 500 Hz ~ 4.5 kHz)
• Efficiency (dBA): 84.00 (3 dB improvement from 81.00)
• Product Status: Active (versus Obsolete)
• RoHS Status: ROHS3 Compliant (versus RoHS non-compliant)
• Ingress Protection: Water Resistant (added environmental protection)

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The AS05008PR-WR-R is the direct manufacturer substitute for the obsolete AS05008PR. Both components share identical electrical impedance (8 Ohms), mechanical form factor (50mm diameter round), and termination interface (solder eyelets), ensuring direct circuit compatibility without redesign.

For RoHS Compliance Requirements: Applications requiring RoHS3 compliance must transition to the AS05008PR-WR-R. The original AS05008PR is RoHS non-compliant and unsuitable for regulated markets. The substitute meets current environmental standards.

For Enhanced Performance Applications: The AS05008PR-WR-R provides superior acoustic performance (84 dB versus 81 dB SPL) and increased power handling (1 W rated versus 100 mW), making it suitable for applications requiring higher output levels or extended frequency response (550 Hz ~ 5 kHz versus 500 Hz ~ 4.5 kHz).

For Environmental Protection: Applications requiring water resistance or moisture exposure protection must use the AS05008PR-WR-R, which includes water-resistant ingress protection. The original part offers no environmental protection rating.

Height Consideration: The AS05008PR-WR-R has a maximum seated height of 0.492" (12.50mm) compared to 0.374" (9.50mm) for the original part. Verify available vertical clearance in the enclosure before substitution.

Frequently Asked Questions (FAQ)

Q: Can the AS05008PR-WR-R be used as a direct replacement for the AS05008PR?

A: Yes. Both components maintain identical impedance (8 Ohms), diameter (50mm), port location (top), and solder eyelet termination. The AS05008PR-WR-R is electrically and mechanically interchangeable. However, verify that the increased height (12.50mm versus 9.50mm) does not exceed available clearance in your enclosure.

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

A: The AS05008PR-WR-R provides higher power handling (1 W rated versus 100 mW), improved efficiency (84 dB versus 81 dB SPL), and expanded frequency range (550 Hz ~ 5 kHz versus 500 Hz ~ 4.5 kHz). These represent performance enhancements rather than incompatibilities.

Q: Is the AS05008PR-WR-R suitable for applications requiring RoHS compliance?

A: Yes. The AS05008PR-WR-R is ROHS3 compliant. The original AS05008PR is RoHS non-compliant and cannot be used in regulated applications. For any new design or production requiring environmental compliance, the AS05008PR-WR-R is the required choice.

Q: Does the water-resistant rating of the AS05008PR-WR-R affect its performance in dry environments?

A: No. Water resistance is an additional protective feature that does not degrade performance in standard dry operating conditions. The coated paper cone material provides the same acoustic characteristics as the uncoated material in the original part.

Q: What is the impact of the increased height on PCB layout?

A: The AS05008PR-WR-R requires 0.118" (3.00mm) additional vertical clearance compared to the AS05008PR. Verify that your enclosure or mounting structure accommodates the maximum seated height of 0.492" (12.50mm) before finalizing the substitution.

Q: Are both parts available from the same manufacturer?

A: Yes. Both the AS05008PR and AS05008PR-WR-R are manufactured by PUI Audio, Inc. The AS05008PR-WR-R is the active production substitute for the obsolete AS05008PR.
