AS04008PS-4W Equivalent & Substitute Parts

Part Overview

The AS04008PS-4W is an 8 Ohm general purpose speaker rated at 2 W with a frequency range of 380 Hz to 20 kHz, manufactured by PUI Audio, Inc. This speaker features a top-mounted oval rectangular frame with a paper cone and neodymium-iron-boron magnet, delivering 84 dBA sound pressure level at 1W/500mm. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS04008PS-4W is determined by strict equivalence across the following critical parameters:

• Electrical Characteristics: Impedance (8 Ohms), rated power (2 W), maximum power (4 W), frequency range (380 Hz ~ 20 kHz), and self-resonant frequency (380 Hz) must remain identical
• Acoustic Performance: Sound pressure level (84 dBA at 1W/500mm) must be maintained
• Mechanical Compatibility: Port location (top), shape (oval rectangular frame), overall dimensions (40.00mm x 28.30mm), and termination type (solder eyelet) must match
• Material Specification: Cone material (paper) and magnet type (Nd-Fe-B) must be consistent

The AS04008PS-4W-R meets all these criteria and is therefore a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The AS04008PS-4W-R is the direct equivalent substitute for the obsolete AS04008PS-4W. Both components share identical electrical, acoustic, and mechanical specifications across all critical parameters. The primary differences are product status and regulatory compliance:

• AS04008PS-4W-R is currently in active production status with ROHS3 compliance, making it the preferred selection for new designs and ongoing procurement
• AS04008PS-4W is obsolete and non-compliant with RoHS3 standards

The AS04008PS-4W-R accommodates a maximum seated height of 0.472" (12.00mm) compared to 0.453" (11.50mm) for the original part. This 0.019" (0.50mm) difference must be evaluated within the mechanical constraints of the target application to ensure proper fit and acoustic performance.

Frequently Asked Questions (FAQ)

Q: Can AS04008PS-4W-R be used as a direct replacement for AS04008PS-4W?

A: Yes. Both components are electrically and acoustically equivalent with identical impedance (8 Ohms), rated power (2 W), frequency range (380 Hz ~ 20 kHz), and sound pressure level (84 dBA). Mechanical dimensions and termination types are identical. The seated height difference of 0.50mm must be verified against application constraints.

Q: What is the primary reason to substitute AS04008PS-4W?

A: The AS04008PS-4W is obsolete. The AS04008PS-4W-R provides an active, production-available equivalent with improved regulatory compliance (ROHS3).

Q: Are there packaging differences between these parts?

A: Yes. The AS04008PS-4W-R is supplied in tray packaging, while the original part's packaging specification is not provided. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the 0.50mm height difference affect compatibility?

A: The seated height increase from 11.50mm to 12.00mm is minimal but must be evaluated within your specific mechanical design. Verify clearance and mounting constraints before implementation.

Q: Are both parts RoHS compliant?

A: No. The AS04008PS-4W is RoHS non-compliant. The AS04008PS-4W-R is ROHS3 compliant, meeting current regulatory requirements for electronic component procurement.
