GA0571 Equivalent & Substitute Parts

Part Overview

The GA0571 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 shape. The part is currently in active production status with full RoHS3 compliance. 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 GF0571 is identified as a substitute for the GA0571 based on the following matching parameters:

• Impedance: 8 Ohms (identical)
• Power - Rated: 250 mW (identical)
• Power - Max: 500 mW (identical)
• Port Location: Top (identical)
• Shape: Round (identical)
• Size / Dimension: 2.244" Dia (57.00mm) (identical)
• Termination: Solder Eyelet(s) (identical)
• RoHS3 Compliance: Both parts meet RoHS3 requirements

Variations between the parts exist in frequency range, efficiency rating, magnet material, and physical height. These differences must be evaluated against specific application requirements to determine suitability for substitution.

Parameter Comparison

Engineering Selection Recommendations

Both GA0571 and GF0571 are active production parts with identical RoHS3 and REACH compliance status. Selection between these parts must account for the following documented differences:

The GA0571 provides higher efficiency at 88.00 dBA with Alnico magnet construction and a narrower frequency response optimized for 400 Hz to 4 kHz applications. The GF0571 offers extended frequency range coverage from 380 Hz to 8.1 kHz with Ferrite magnet construction and lower efficiency at 86.00 dBA. The GF0571 is 0.059" (1.50mm) shorter in seated height.

Applications requiring the specific frequency response and efficiency characteristics of the GA0571 should not substitute with the GF0571 without verification that the extended frequency range and reduced efficiency are acceptable. Conversely, applications benefiting from extended frequency coverage and reduced height may use the GF0571 where the 2 dBA efficiency reduction is tolerable.

Frequently Asked Questions (FAQ)

Q: Can the GF0571 be used as a direct replacement for the GA0571?

A: Both parts share identical impedance (8 Ohms), power ratings (250 mW rated, 500 mW max), port location (top), shape (round), diameter (57.00mm), and termination type (solder eyelet). However, they differ in frequency response, efficiency, magnet material, and height. Substitution is valid only when the application requirements accommodate the GF0571's extended frequency range (380 Hz ~ 8.1 kHz), lower efficiency (86.00 dBA vs 88.00 dBA), and reduced height (18.50mm vs 20.00mm).

Q: What is the significance of the magnet material difference between Alnico and Ferrite?

A: The GA0571 uses Alnico (AlNiCo) magnet construction while the GF0571 uses Ferrite. This material difference contributes to the efficiency variation and frequency response characteristics documented in the parameter comparison table. The choice between these materials affects acoustic performance and should be evaluated against specific application requirements.

Q: Are there packaging differences between these parts?

A: Yes. The GA0571 is supplied in Bag packaging while the GF0571 is supplied in Box packaging. This affects handling, storage, and inventory management but does not impact electrical or mechanical compatibility.

Q: Do both parts meet compliance requirements?

A: Both GA0571 and GF0571 are RoHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8518.29.8000 HTSUS code. Compliance status is equivalent between the two parts.

Q: What is the height difference and does it matter?

A: The GA0571 has a maximum seated height of 0.787" (20.00mm) while the GF0571 measures 0.728" (18.50mm). This 0.059" (1.50mm) difference may be significant in space-constrained applications. Verify mechanical clearance requirements before substitution.
