GA0776M Equivalent & Substitute Parts

Part Overview

The GA0776M is an 8 Ohm general purpose speaker manufactured by CUI Devices, rated at 1 W with a top port configuration. This speaker operates across a frequency range of 320 Hz to 25 kHz and delivers 90 dB SPL at 1W/500mm. The unit features a round, square frame with polyester/PET cone material and Alnico magnet construction. The GA0776M is an active product with full RoHS3 compliance, making it suitable for standard audio applications requiring compact speaker solutions. Alternative models may be required due to inventory constraints, specific frequency response requirements, or magnet material preferences.

Key Parameters

Substitute Part Grouping Explanation

The GF0776M qualifies as a direct substitute for the GA0776M based on the following critical parameters:

Matching Parameters:

• Impedance: 8 Ohms (identical)
• Power Rating: 1 W rated, 2 W maximum (identical)
• Port Location: Top (identical)
• Shape: Round, Square Frame (identical)
• Physical Dimensions: 77.00mm x 77.00mm (identical)
• Termination: Solder Eyelet(s) (identical)
• Compliance: ROHS3 Compliant, REACH Unaffected (identical)

Differing Parameters:

• Frequency Range: GA0776M operates 320 Hz ~ 25 kHz; GF0776M operates 360 Hz ~ 11 kHz
• Efficiency: GA0776M delivers 90 dB SPL; GF0776M delivers 91 dB SPL
• Magnet Material: GA0776M uses Alnico; GF0776M uses Ferrite
• Height: GA0776M seated height 25.10mm; GF0776M seated height 24.00mm
• Packaging: GA0776M supplied in Bag; GF0776M supplied in Box

The GF0776M maintains electrical and mechanical compatibility while offering higher efficiency and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both GA0776M and GF0776M are active products with full regulatory compliance (ROHS3 and REACH). Selection between these parts should be based on application-specific frequency response requirements:

Select GA0776M when:

• Extended low-frequency response below 360 Hz is required
• Full bandwidth coverage to 25 kHz is necessary
• Alnico magnet characteristics are specified in design requirements

Select GF0776M when:

• Frequency response limited to 360 Hz ~ 11 kHz is acceptable
• Higher efficiency (91 dB SPL vs. 90 dB SPL) provides system advantage
• Ferrite magnet material meets design specifications
• Reduced seated height (24.00mm vs. 25.10mm) accommodates space constraints
• Improved inventory availability is a procurement priority

Both parts maintain identical electrical impedance, power ratings, physical footprint, and compliance certifications, ensuring direct substitution within these parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can GF0776M replace GA0776M in existing designs? A: Yes, provided the application does not require frequency response below 360 Hz or above 11 kHz. Both parts share identical impedance (8 Ohms), power ratings (1 W rated, 2 W max), physical dimensions (77mm x 77mm), and termination style (Solder Eyelet). Verify frequency response requirements before substitution.

Q: What is the difference in magnet material between these parts? A: GA0776M uses Alnico (Aluminum-Nickel-Cobalt) magnets, while GF0776M uses Ferrite magnets. Both materials are suitable for general purpose speaker applications. Ferrite magnets in the GF0776M contribute to the 1 dB efficiency increase (91 dB SPL vs. 90 dB SPL).

Q: Are there packaging differences? A: Yes. GA0776M is supplied in Bag packaging, while GF0776M is supplied in Box packaging. This does not affect electrical or mechanical compatibility.

Q: What is the seated height difference? A: GA0776M has a maximum seated height of 25.10mm, while GF0776M measures 24.00mm. This 1.10mm difference may be relevant for space-constrained applications.

Q: Do both parts meet the same compliance standards? A: Yes. Both GA0776M and GF0776M are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements.

Q: Which part should I select for audio bandwidth below 360 Hz? A: Select GA0776M, which operates from 320 Hz. GF0776M's frequency range begins at 360 Hz and would not provide adequate low-frequency response for applications requiring coverage below this threshold.
