AS09008PO-2-R Equivalent & Substitute Parts

Part Overview

The AS09008PO-2-R is an 8 Ohm general purpose speaker rated at 5 W with a top port configuration and 87 dB sound pressure level (SPL). Manufactured by PUI Audio, Inc., this speaker features a paper cone, ferrite magnet, and oval rectangular frame with solder eyelet termination. The part is currently obsolete, making identification of equivalent substitute components essential for ongoing system support and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS09008PO-2-R is determined by the following critical parameters:

• Impedance: Must remain 8 Ohms for circuit compatibility
• Power Rating: Rated power of 5 W and maximum power of 8 W must be maintained
• Physical Dimensions: Oval rectangular frame with 90.00 mm L x 50.00 mm W footprint and maximum seated height of 39.50 mm
• Port Location: Top port configuration required for mechanical integration
• Termination: Solder eyelet(s) for electrical connection
• Magnet Type: Ferrite magnet construction
• Compliance: ROHS3 compliance required

The AS09008PO-11-R meets these substitution criteria while maintaining electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AS09008PO-11-R is an active production substitute for the obsolete AS09008PO-2-R. Both components share identical impedance, power ratings, physical footprint, port location, and magnet construction. The substitute maintains ROHS3 compliance and identical electrical termination.

Differences in frequency response characteristics (AS09008PO-11-R: 0 Hz ~ 10 kHz versus AS09008PO-2-R: 200 Hz ~ 20 kHz) and efficiency rating (85.00 dB SPL versus 87.00 dB SPL) must be evaluated against specific application requirements. The substitute's lower self-resonant frequency (180 Hz versus 200 Hz) and reduced maximum seated height (38.50 mm versus 39.50 mm) represent minor variations within the same product family.

Selection of the AS09008PO-11-R is supported by its active product status and continued availability, ensuring supply chain continuity for applications requiring this speaker specification.

Frequently Asked Questions (FAQ)

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

A: Yes, provided that the application tolerates the frequency response range of 0 Hz ~ 10 kHz and the 85.00 dB SPL efficiency rating. The impedance, power ratings, physical dimensions, port location, and termination are identical.

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

A: The primary differences are frequency response range, self-resonant frequency, efficiency rating, and maximum seated height. The AS09008PO-11-R operates across a lower frequency range (0 Hz ~ 10 kHz) with 2 dB lower efficiency and 1 mm reduced height.

Q: Are both parts mechanically compatible?

A: Yes. Both components share the same oval rectangular frame dimensions (90.00 mm L x 50.00 mm W), top port location, and solder eyelet termination. The AS09008PO-11-R has a maximum seated height of 38.50 mm compared to 39.50 mm for the AS09008PO-2-R, representing a 1 mm reduction.

Q: What is the packaging difference?

A: The AS09008PO-2-R is supplied with standard packaging, while the AS09008PO-11-R is supplied in Tray packaging.

Q: Are both parts RoHS compliant?

A: Yes, both the AS09008PO-2-R and AS09008PO-11-R are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8518.29.8000) classifications.

Q: Why is the AS09008PO-2-R marked as obsolete?

A: The AS09008PO-2-R has been discontinued by PUI Audio, Inc. The AS09008PO-11-R represents the active production equivalent within the same product series.
