Key Parameters

Substitute Part Grouping Explanation

The GA0576M from CUI Devices is identified as a substitute for the AS05004PS-R based on the following shared parameters:

• Port Location: Top (matching orientation requirement)
• Shape: Round, Square Frame (matching mechanical form factor)
• Size / Dimension: 57.00 mm x 57.00 mm (identical footprint)
• Termination: Solder Eyelet(s) (compatible connection method)
• Technology: Magnetic (same operational principle)
• Type: General Purpose (same application category)

The GA0576M differs in impedance (8 Ohms vs. 4 Ohms), power rating (250 mW vs. 3 W), frequency range (500 Hz ~ 12 kHz vs. 200 Hz ~ 20 kHz), efficiency (80 dB vs. 84 dB), and physical height (19.50 mm vs. 40.00 mm). These differences require circuit-level evaluation for compatibility in specific applications.

Parameter Comparison

Engineering Selection Recommendations

The GA0576M is an active product from CUI Devices and represents a viable alternative for applications where the AS05004PS-R is no longer available. The substitute maintains identical mechanical mounting dimensions (57.00 mm x 57.00 mm footprint) and top port orientation, enabling direct physical replacement in existing enclosures.

Circuit-level compatibility requires verification of impedance matching. The GA0576M operates at 8 Ohms compared to the AS05004PS-R's 4 Ohm impedance, necessitating impedance network adjustment in the driving circuit. The GA0576M's reduced power rating (250 mW vs. 3 W) and narrower frequency range (500 Hz ~ 12 kHz vs. 200 Hz ~ 20 kHz) must be evaluated against application requirements.

The GA0576M is RoHS3 Compliant and carries REACH Unaffected status, meeting current regulatory requirements. The AS05004PS-R's obsolete status and the GA0576M's active product status support long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the GA0576M be used as a direct drop-in replacement for the AS05004PS-R?

A: Physical mounting is compatible due to identical footprint dimensions (57.00 mm x 57.00 mm) and top port orientation. Electrical compatibility requires circuit modification to accommodate the impedance difference (8 Ohms vs. 4 Ohms).

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

A: The AS05004PS-R is a 4 Ohm, 3 W speaker with extended frequency response (200 Hz ~ 20 kHz). The GA0576M is an 8 Ohm, 250 mW speaker with a narrower frequency range (500 Hz ~ 12 kHz). The GA0576M is also physically more compact (19.50 mm height vs. 40.00 mm).

Q: Are there compliance or regulatory differences?

A: The GA0576M is RoHS3 Compliant with active product status. The AS05004PS-R is classified as Obsolete. Both carry REACH Unaffected status and share the same ECCN and HTSUS classifications.

Q: What packaging is available for the GA0576M?

A: The GA0576M is supplied in Box packaging. The AS05004PS-R packaging information is not specified in available documentation.

Q: How do the cone materials differ?

A: The AS05004PS-R uses a paper cone, while the GA0576M uses Polyester/Polyethylene Terephthalate (PET). The AS05004PS-R employs a Ferrite magnet; the GA0576M uses Alnico (AlNiCo) magnet material.
