GA0876 Equivalent & Substitute Parts

Part Overview

The GA0876 is an 8 Ohm general purpose speaker rated at 1 W with a top port configuration and 90 dBA sound pressure level. Manufactured by CUI Devices, this component operates across a frequency range of 200 Hz to 14 kHz and features an Alnico magnet with a paper cone. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in applications where the main part is unavailable or when design requirements permit higher performance specifications within the same form factor and termination standard.

Key Parameters

Substitute Part Grouping Explanation

The GF0876 qualifies as a substitute for the GA0876 based on the following matching parameters:

• Impedance: 8 Ohms (identical)
• Port Location: Top (identical)
• Shape: Round, Square Frame (identical)
• Size / Dimension: 87.00mm x 87.00mm (identical)
• Height - Seated (Max): 32.50mm (identical)
• Termination: Solder Eyelet(s) (identical)
• Material - Cone: Paper (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The GF0876 differs in magnet material (Ferrite vs. Alnico), rated power (2 W vs. 1 W), maximum power (3 W vs. 3 W), efficiency (99.00 dBA vs. 90.00 dBA), and frequency range (232 Hz ~ 18 kHz vs. 200 Hz ~ 14 kHz). These differences represent performance enhancements within the same mechanical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both GA0876 and GF0876 maintain identical mechanical form factors, mounting configurations, and regulatory compliance status. The GF0876 provides increased rated power capacity (2 W vs. 1 W) and higher acoustic efficiency (99.00 dBA vs. 90.00 dBA) while maintaining the same maximum power rating and impedance specification. The magnet material transition from Alnico to Ferrite represents a manufacturing variation that does not affect electrical compatibility or mechanical interchangeability.

Selection between these parts depends on application power requirements and acoustic output specifications. Both parts are active products with full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the GF0876 directly replace the GA0876 in existing designs?

A: Yes. Both parts share identical impedance (8 Ohms), mechanical dimensions (87.00mm x 87.00mm), height (32.50mm), port location (top), termination type (solder eyelet), and form factor. The GF0876 operates within the same electrical envelope and mounting configuration.

Q: What are the key differences between GA0876 and GF0876?

A: The GF0876 features higher rated power (2 W vs. 1 W), increased acoustic efficiency (99.00 dBA vs. 90.00 dBA), extended frequency range (232 Hz ~ 18 kHz vs. 200 Hz ~ 14 kHz), and uses Ferrite magnets instead of Alnico. Maximum power rating remains 3 W for both parts.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1). Regulatory requirements are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on power and acoustic output requirements. The GF0876 is suitable for applications requiring higher power handling and acoustic efficiency. The GA0876 remains appropriate for lower power applications within the 1 W rated specification.

Q: Are the solder eyelet terminations compatible with the same PCB footprints?

A: Yes. Both parts use identical solder eyelet termination and maintain the same mechanical dimensions, ensuring compatibility with existing PCB layouts and assembly processes.
