Key Parameters

Substitute Part Grouping Explanation

The AS07104PO-WR-R is identified as a substitute for the AS07108PO-2-WR-R based on the following substitution criteria:

Mechanical Compatibility:

• Identical footprint dimensions: 2.795" L x 1.614" W (71.00mm x 41.00mm)
• Same shape configuration: Oval, Rectangular Frame
• Top port location maintained
• Solder Eyelet termination type consistent
• Water resistant ingress protection preserved

Electrical Considerations:

• Impedance differs: 4 Ohms (substitute) vs. 8 Ohms (main part)
• Power rating differs: 3 W rated / 5 W max (substitute) vs. 4 W rated / 6 W max (main part)
• Frequency range differs: 100 Hz ~ 20 kHz (substitute) vs. 350 Hz ~ 20 kHz (main part)
• Efficiency differs: 86.00 dB SPL (substitute) vs. 85.00 dB SPL (main part)

Material & Construction:

• Paper, Coated cone material maintained
• Nd-Fe-B magnet technology consistent
• Both components from PUI Audio AS series

Regulatory & Compliance:

• REACH Unaffected status maintained
• ECCN EAR99 classification consistent
• Substitute is RoHS3 Compliant (active product status)

Parameter Comparison

Engineering Selection Recommendations

The AS07104PO-WR-R serves as a mechanical and form-factor substitute for the obsolete AS07108PO-2-WR-R. Both components share identical external dimensions, port configuration, and mounting interface, enabling direct physical replacement in existing assemblies.

The substitute component is currently in active production status with RoHS3 compliance certification, providing supply chain continuity for applications requiring the AS series speaker form factor. The mechanical compatibility is confirmed through matching footprint dimensions (71.00mm x 41.00mm) and identical port location.

Electrical parameter differences exist between the two components. The substitute operates at 4 Ohms impedance with 3 W rated power, compared to the main part's 8 Ohm impedance and 4 W rated power. The substitute provides extended low-frequency response (100 Hz vs. 350 Hz lower limit) and marginally higher efficiency (86.00 dB vs. 85.00 dB SPL). These differences require circuit-level evaluation to confirm functional equivalence within the target application.

Frequently Asked Questions (FAQ)

Q: Can AS07104PO-WR-R be used as a direct replacement for AS07108PO-2-WR-R?

A: Mechanical substitution is possible due to identical footprint dimensions and port configuration. However, electrical parameter differences require circuit validation. The impedance change from 8 Ohms to 4 Ohms and power rating reduction from 4 W to 3 W necessitate verification of amplifier compatibility and power delivery capability.

Q: What are the key mechanical compatibility factors?

A: Both components share identical external dimensions (71.00mm x 41.00mm), top port location, oval rectangular frame shape, and solder eyelet termination. The substitute has a reduced seated height (25.00mm vs. 28.00mm), which may affect enclosure fit in space-constrained applications.

Q: How do the electrical specifications differ?

A: The substitute operates at 4 Ohms impedance versus the main part's 8 Ohms. Rated power is 3 W (max 5 W) for the substitute compared to 4 W (max 6 W) for the main part. The substitute provides lower frequency response starting at 100 Hz versus 350 Hz for the main part.

Q: What is the product availability status?

A: The AS07108PO-2-WR-R is obsolete with 964 units in current inventory. The AS07104PO-WR-R is an active product with 2,163 units available, providing ongoing supply availability.

Q: Are there compliance differences between the two components?

A: Both components maintain REACH Unaffected and EAR99 ECCN classification. The substitute is RoHS3 Compliant, whereas the main part's RoHS status is not specified. Both are water resistant with identical material composition (paper coated cone, Nd-Fe-B magnet).
