AS04008PS-4W-WR Equivalent & Substitute Parts

Part Overview

The AS04008PS-4W-WR is an 8 Ohm general purpose speaker rated at 2 W with a frequency range of 380 Hz to 20 kHz. This component features a top-mounted oval rectangular frame with a paper coated cone and neodymium-iron-boron magnet. The speaker delivers 84 dBA sound pressure level at 1W/500mm and includes water resistant ingress protection with solder eyelet termination.

The AS04008PS-4W-WR is classified as obsolete. Locating equivalent or substitute parts becomes necessary when original inventory is depleted or when design revisions require components with improved compliance status or availability.

Substitute Part Grouping Explanation

Substitution eligibility for the AS04008PS-4W-WR is determined by strict equivalence across the following electrical and mechanical parameters:

• Impedance: 8 Ohms (exact match required)
• Power Rating: 2 W rated, 4 W maximum (exact match required)
• Frequency Range: 380 Hz ~ 20 kHz (exact match required)
• Self Resonant Frequency: 380 Hz (exact match required)
• Efficiency: 84.00 dBA at 1W/500mm (exact match required)
• Port Location: Top (exact match required)
• Shape: Oval, Rectangular Frame (exact match required)
• Termination: Solder Eyelet(s) (exact match required)
• Ingress Protection: Water Resistant (exact match required)
• Mounting Dimensions: 40.00mm x 28.30mm (exact match required)

The AS04008PS-4W-WR-R meets all substitution criteria and is identified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AS04008PS-4W-WR-R is a direct functional equivalent to the AS04008PS-4W-WR across all critical electrical and mechanical parameters. The primary distinctions are:

• Product Status: The AS04008PS-4W-WR-R is Active, whereas the original part is Obsolete. This ensures long-term availability and supply chain continuity.
• RoHS Compliance: The AS04008PS-4W-WR-R is ROHS3 compliant, addressing regulatory requirements that the original part does not meet.
• Packaging: The AS04008PS-4W-WR-R is supplied in Tray packaging, compared to unspecified packaging for the original.
• Height Variance: The AS04008PS-4W-WR-R has a maximum seated height of 0.472" (12.00mm) versus 0.453" (11.50mm) for the original. This 0.019" (0.50mm) difference must be evaluated against available mounting clearance in the application.
• Inventory Availability: The AS04008PS-4W-WR-R has significantly higher stock levels (10119 Pcs vs. 1053 Pcs).

Selection of the AS04008PS-4W-WR-R is appropriate when regulatory compliance and long-term availability are required, provided the increased height does not conflict with mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Are the AS04008PS-4W-WR and AS04008PS-4W-WR-R electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 8 Ohm impedance, 2 W rated power, 4 W maximum power, 380 Hz to 20 kHz frequency range, and 84 dBA efficiency. They are functionally equivalent in audio circuit applications.

Q: What is the significance of the height difference between these parts?

A: The AS04008PS-4W-WR-R has a maximum seated height of 0.472" (12.00mm) compared to 0.453" (11.50mm) for the AS04008PS-4W-WR. This 0.50mm difference must be verified against available mounting depth in the enclosure or device design to ensure mechanical fit.

Q: Why is RoHS compliance important for this substitution?

A: The AS04008PS-4W-WR-R is ROHS3 compliant, whereas the original is non-compliant. For applications subject to RoHS regulations or customer requirements, the AS04008PS-4W-WR-R is the appropriate selection.

Q: Does packaging affect the substitution decision?

A: The AS04008PS-4W-WR-R is supplied in Tray packaging. If your procurement or assembly process requires specific packaging formats, this should be confirmed with your supplier. Electrical and mechanical performance are unaffected by packaging type.

Q: Can I use the AS04008PS-4W-WR-R in place of the AS04008PS-4W-WR in existing designs?

A: Yes, provided the 0.50mm height increase does not violate mechanical constraints. All electrical parameters and mounting dimensions (40.00mm x 28.30mm) are identical. Verify clearance before implementation.
