AS07008PO-2-R Equivalent & Substitute Parts

Part Overview

The AS07008PO-2-R is an 8 Ohm general purpose speaker rated at 2 W with a top port configuration, manufactured by PUI Audio, Inc. This model operates across a frequency range of 450 Hz to 20 kHz and delivers 85 dB SPL at 1W/500mm. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AS07008PO-2-R are qualified based on the following critical parameters:

• Impedance Match: 8 Ohms (electrical compatibility requirement)
• Power Rating: 2 W rated, 5 W maximum (circuit design compatibility)
• Port Location: Top port configuration (mechanical installation requirement)
• Termination Type: Solder Eyelet(s) (assembly compatibility)
• Magnet Material: Nd-Fe-B (performance consistency)
• Technology: Magnetic (functional equivalence)

The identified substitute parts maintain these core parameters while operating within acceptable variations in frequency response, efficiency, and physical dimensions. Frequency range variations and minor efficiency differences do not affect functional substitution in general purpose speaker applications.

Parameter Comparison

Engineering Selection Recommendations

AS07008MO-R: This substitute is actively manufactured and ROHS3 compliant. It maintains identical impedance, power ratings, and termination specifications. The efficiency is 1 dB lower (84 dB vs. 85 dB), and the frequency range extends lower (150 Hz vs. 450 Hz). Physical dimensions are within 0.5 mm variation. This part includes IP55 ingress protection and operates across -20°C to 60°C. Selection is appropriate for applications where extended low-frequency response and environmental protection are beneficial.

AS07008PO-4-R: This substitute is actively manufactured and ROHS3 compliant. It matches the main part in impedance, power ratings, efficiency (85 dB), termination, and self-resonant frequency. The frequency range extends lower (200 Hz vs. 450 Hz). Physical dimensions are within 0.5 mm variation. Operating temperature range is -30°C to 60°C, providing extended cold-temperature capability. Selection is appropriate for applications requiring equivalent acoustic performance with improved low-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can AS07008MO-R or AS07008PO-4-R be used as direct replacements for AS07008PO-2-R?

A: Both parts are electrically and mechanically compatible. They maintain the same 8 Ohm impedance, 2 W rated power, 5 W maximum power, top port location, and solder eyelet termination. Physical dimensions vary by less than 1 mm. Both are actively manufactured and ROHS3 compliant, addressing the obsolescence of the original part.

Q: What are the key differences between the two substitute options?

A: AS07008MO-R offers extended low-frequency response (150 Hz vs. 200 Hz) and IP55 environmental protection, with 1 dB lower efficiency. AS07008PO-4-R maintains identical efficiency and self-resonant frequency to the original part, with extended cold-temperature operation (-30°C vs. unspecified). Both have equivalent acoustic performance in the upper frequency range.

Q: Are there packaging differences between these parts?

A: AS07008PO-2-R was supplied in Bulk packaging. AS07008MO-R is supplied in Tray packaging. AS07008PO-4-R packaging is not specified in available data. Verify packaging requirements for your procurement and assembly processes.

Q: Do these substitutes affect circuit design or PCB layout?

A: No. All three parts maintain identical electrical specifications (8 Ohms, 2 W rated, 5 W maximum) and termination type (solder eyelet). PCB footprints and circuit connections remain unchanged. Minor physical dimension variations (less than 1 mm) do not affect standard mounting practices.

Q: Which substitute should be selected for new designs?

A: Both AS07008MO-R and AS07008PO-4-R are active products suitable for new designs. AS07008PO-4-R is recommended if efficiency matching and extended cold-temperature operation are required. AS07008MO-R is recommended if extended low-frequency response and environmental protection are beneficial.
