Key Parameters

Substitute Part Grouping Explanation

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

• Impedance: Must be 8 Ohms to maintain circuit compatibility
• Power Rating: Rated power must be 2 W with maximum power handling of 5 W
• Port Location: Must feature top port configuration
• Termination: Must use Solder Eyelet(s) for direct PCB integration
• Technology & Magnet Material: Must employ Magnetic technology with Nd-Fe-B magnets
• Compliance: Must maintain ROHS3 compliance and equivalent environmental certifications

The substitute parts AS07008MO-R and AS07008PO-4-WR-R meet these core electrical and mechanical requirements while accommodating the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

AS07008MO-R is suitable for applications where extended low-frequency response is beneficial. This substitute provides a lower self-resonant frequency of 300 Hz compared to the original 450 Hz, enabling operation down to 150 Hz. The rectangular shape and reduced height (23.00mm vs 24.60mm) may require mechanical verification for PCB clearance. Enhanced ingress protection (IP55) provides superior dust and moisture resistance. Product status is Active, ensuring long-term availability.

AS07008PO-4-WR-R maintains the closest electrical and mechanical alignment with the original part. It preserves the oval rectangular frame shape and matches the 85 dB efficiency rating. The extended operating temperature range (-30°C to 60°C versus unspecified for the original) provides enhanced thermal performance. Dimensional compatibility is equivalent to AS07008MO-R. Product status is Active with confirmed availability.

Both substitutes maintain ROHS3 compliance and equivalent environmental certifications required for regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can AS07008MO-R be used as a direct replacement for AS07008PO-2-WR-R?

A: AS07008MO-R meets all core electrical requirements: 8 Ohm impedance, 2 W rated power, 5 W maximum power, top port configuration, and solder eyelet termination. Mechanical differences include rectangular shape versus oval rectangular frame, and a 0.5mm reduction in height. Verify PCB layout compatibility before substitution.

Q: What is the primary difference between the two substitute parts?

A: AS07008PO-4-WR-R maintains the oval rectangular frame shape and matches the original 85 dB efficiency. AS07008MO-R uses a rectangular shape with 84 dB efficiency but extends the frequency range to 150 Hz. Both are electrically compatible with the original circuit.

Q: Are there frequency response implications when substituting?

A: The original part operates from 450 Hz to 20 kHz. AS07008MO-R extends low-frequency response to 150 Hz, while AS07008PO-4-WR-R operates from 200 Hz to 20 kHz. System frequency response characteristics will shift accordingly. Acoustic design verification is recommended for applications with specific frequency requirements.

Q: Do the substitute parts have different packaging considerations?

A: AS07008PO-2-WR-R ships in Bulk packaging. AS07008MO-R ships in Tray packaging. AS07008PO-4-WR-R packaging is not specified. Verify procurement and handling requirements with supplier documentation.

Q: Are both substitutes currently available?

A: Yes. AS07008MO-R has 1019 pieces in stock. AS07008PO-4-WR-R has 817 pieces in stock. Both maintain Active product status, ensuring continued availability for future procurement.
