Key Parameters

Substitute Part Grouping Explanation

The AS04008PO-2-WR-R qualifies as a direct substitute based on the following critical parameters:

• Electrical Compatibility: Identical impedance (8 Ohms), rated power (1 W), maximum power (2 W), and frequency range (450 Hz ~ 20 kHz)
• Acoustic Performance: Matching efficiency rating of 84.00 dBA
• Mechanical Compatibility: Identical dimensions (1.575" L x 1.114" W / 40.00mm x 28.30mm), same port location (top), and identical frame shape (oval, rectangular)
• Material Consistency: Identical cone material (paper, coated) and magnet type (Nd-Fe-B)
• Environmental Protection: Matching water-resistant ingress protection
• Termination: Identical solder eyelet termination

The primary distinction is product status and packaging format, with AS04008PO-2-WR-R being an active product supplied in tray packaging.

Parameter Comparison

Engineering Selection Recommendations

The AS04008PO-2-WR-R is the direct substitute for the obsolete AS04008PO-2-WR. Selection of the substitute is based on:

• Product Continuity: AS04008PO-2-WR-R maintains active product status with confirmed inventory availability (991 Pcs), ensuring supply chain reliability
• Regulatory Compliance: AS04008PO-2-WR-R achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. This compliance improvement is advantageous for applications subject to RoHS regulations
• Dimensional Tolerance: The seated height difference of 0.019" (0.50mm) is within typical mechanical tolerance ranges for speaker mounting applications and does not affect electrical or acoustic performance
• Electrical and Acoustic Equivalence: All critical electrical parameters, acoustic characteristics, and mechanical dimensions remain identical, ensuring direct functional replacement

Frequently Asked Questions (FAQ)

Q: Can AS04008PO-2-WR-R be used as a direct replacement for AS04008PO-2-WR?

A: Yes. Both parts share identical electrical specifications (8 Ohms, 1 W rated power), acoustic performance (84.00 dBA, 450 Hz ~ 20 kHz), mechanical dimensions (40.00mm x 28.30mm), and termination type (solder eyelet). The seated height difference of 0.50mm is within standard mechanical tolerance and does not impact functionality.

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

A: The AS04008PO-2-WR is obsolete with RoHS non-compliant status, while AS04008PO-2-WR-R is an active product with ROHS3 compliance and tray packaging. Both are electrically and acoustically equivalent.

Q: Does the packaging format affect compatibility?

A: No. Packaging format (standard versus tray) affects only handling, storage, and supply chain logistics. It does not alter the electrical, acoustic, or mechanical characteristics of the speaker component itself.

Q: Are there any impedance or power rating differences?

A: No. Both parts maintain identical impedance (8 Ohms), rated power (1 W), and maximum power (2 W) specifications.

Q: Is the frequency response identical?

A: Yes. Both parts operate across the same frequency range of 450 Hz to 20 kHz with identical self-resonant frequency of 450 Hz and efficiency rating of 84.00 dBA.
