AS09008PO-2-WR-R Equivalent & Substitute Parts

Part Overview

The AS09008PO-2-WR-R is an 8 Ohm general purpose speaker rated at 5 W with a top port configuration, manufactured by PUI Audio, Inc. This speaker operates across a frequency range of 200 Hz to 20 kHz and delivers 87 dBA sound pressure level at 1W/500mm. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS09008PO-2-WR-R is determined by the following critical parameters:

• Impedance: Must be 8 Ohms to maintain circuit compatibility
• Power Rating: Rated power must be 5 W with maximum power tolerance of 8 W
• Port Location: Must feature top port configuration
• Physical Dimensions: Must match 90.00mm x 50.00mm footprint
• Termination Type: Must use Solder Eyelet(s)
• Ingress Protection: Must maintain Water Resistant rating
• Compliance: Must meet ROHS3 requirements

The AS09008PO-11-WR-R qualifies as a substitute based on matching impedance, power rating, port location, physical dimensions, termination type, ingress protection, and regulatory compliance. Variations in frequency range and efficiency rating do not preclude substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The AS09008PO-11-WR-R is a direct substitute for the obsolete AS09008PO-2-WR-R. Both components share identical impedance, power ratings, physical dimensions, port configuration, and termination specifications. The substitute part maintains ROHS3 compliance and water resistant ingress protection, ensuring regulatory and environmental performance parity.

The AS09008PO-11-WR-R is currently in active production status with confirmed inventory availability, providing supply chain continuity for applications previously using the AS09008PO-2-WR-R. The substitute exhibits a 2 dBA reduction in efficiency and a narrower frequency response range (180 Hz ~ 10 kHz versus 200 Hz ~ 20 kHz), with a marginal 1mm reduction in seated height. These variations remain within acceptable tolerances for general purpose speaker applications where the primary electrical and mechanical interface requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the AS09008PO-11-WR-R directly replace the AS09008PO-2-WR-R in existing designs?

A: Yes. Both components share identical impedance (8 Ohms), power ratings (5 W rated, 8 W maximum), physical footprint (90.00mm x 50.00mm), port location (top), and termination type (Solder Eyelet). The mechanical and electrical interfaces are compatible.

Q: What are the differences between these two parts?

A: The AS09008PO-11-WR-R operates across a narrower frequency range (180 Hz ~ 10 kHz versus 200 Hz ~ 20 kHz) and delivers 85 dBA efficiency compared to 87 dBA for the main part. The substitute is 1mm shorter in seated height (38.50mm versus 39.50mm). The substitute is currently in active production, whereas the main part is obsolete.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and water resistant ingress protection ratings. No compliance gaps exist between the two components.

Q: What packaging is available for the substitute part?

A: The AS09008PO-11-WR-R is supplied in Tray packaging. The main part packaging specification was not provided.

Q: Does the frequency range difference affect substitution suitability?

A: Substitution suitability is determined by matching impedance, power rating, physical dimensions, port location, and termination type. Frequency range variation does not preclude substitution when these core parameters align. Application-specific frequency requirements should be evaluated independently.
