GA0576 Equivalent & Substitute Parts

Part Overview

The GA0576 is an 8 Ohm general purpose speaker manufactured by CUI Devices, rated for 250 mW continuous power with a frequency range of 400 Hz to 4 kHz. This component is designed for applications requiring compact audio output with top-mounted port configuration and round/square frame geometry. The part is Active status and ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this speaker category.

Key Parameters

Substitute Part Grouping Explanation

The GF0576 qualifies as a substitute for the GA0576 based on the following matching electrical and mechanical parameters:

• Impedance: Both parts are 8 Ohms
• Power Rating: Both rated for 250 mW continuous, 500 mW maximum
• Port Location: Both feature top-mounted port configuration
• Physical Dimensions: Both measure 57.00 mm x 57.00 mm
• Termination: Both use Solder Eyelet(s)
• Technology: Both employ magnetic speaker technology
• Material - Cone: Both use paper cone construction
• Compliance: Both are ROHS3 compliant

Substitution is valid when the application requirements accommodate the parameter differences identified in the Parameter Comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both GA0576 and GF0576 are Active status products from CUI Devices with ROHS3 compliance and REACH Unaffected designation. Selection between these parts depends on application-specific requirements:

The GA0576 provides higher acoustic efficiency at 88 dB SPL and offers both round and square frame options. The Alnico magnet construction delivers the specified performance at 1W/500mm test conditions.

The GF0576 provides extended frequency response capability (380 Hz to 8.1 kHz versus 400 Hz to 4 kHz) and a lower seated height of 18.50 mm versus 19.50 mm. The Ferrite magnet construction operates at 250 mW/500mm test conditions with 86 dB SPL efficiency.

Both parts maintain identical impedance, rated power, maximum power, port location, physical footprint, and termination type. Substitution is valid when the application can accommodate the acoustic efficiency difference, frequency response variation, magnet material change, and height reduction of the GF0576.

Frequently Asked Questions (FAQ)

Q: Can GF0576 replace GA0576 in existing designs?

A: Yes, provided the application requirements accommodate the parameter differences. Both parts share identical impedance (8 Ohms), power ratings (250 mW rated, 500 mW max), port location (top), and physical footprint (57 x 57 mm). The GF0576 has lower acoustic efficiency (86 dB SPL versus 88 dB SPL) and extended frequency response (380 Hz to 8.1 kHz versus 400 Hz to 4 kHz).

Q: What is the impact of magnet material difference?

A: GA0576 uses Alnico (AlNiCo) magnet material while GF0576 uses Ferrite. Both are magnetic speaker technologies. The magnet material affects acoustic performance characteristics and efficiency testing conditions. GA0576 is tested at 1W/500mm while GF0576 is tested at 250mW/500mm.

Q: Are there mechanical compatibility concerns?

A: The GF0576 has a maximum seated height of 18.50 mm compared to GA0576 at 19.50 mm, a difference of 1.0 mm. Both parts use identical solder eyelet termination and share the same 57 x 57 mm footprint. Verify enclosure clearance for the GA0576 square frame option if mechanical space is constrained.

Q: Do packaging differences affect component selection?

A: GA0576 is supplied in Bag packaging while GF0576 is supplied in Box packaging. This affects handling, storage, and logistics but does not impact electrical or mechanical compatibility. Select based on procurement and inventory management requirements.

Q: Are both parts suitable for current production?

A: Yes, both GA0576 and GF0576 are Active status products with ROHS3 compliance and REACH Unaffected designation, making them suitable for current production environments.
