Key Parameters

Substitute Part Grouping Explanation

The GF0778B from CUI Devices qualifies as a substitute based on the following critical parameters:

• Impedance Match: Both parts operate at 8 Ohms, ensuring direct electrical compatibility in circuit designs
• Port Location: Both feature top-mounted ports, maintaining identical mechanical orientation
• Shape Configuration: Both utilize round, square frame construction
• Termination Type: Both employ solder eyelet(s) for connection
• Magnet Technology: Both use ferrite magnet construction
• Material - Cone: Both feature paper cone construction

The GF0778B operates at reduced power ratings (3 W rated, 5 W maximum) compared to the AS07708PS-3-WR-R (10 W rated, 15 W maximum). The frequency range differs slightly (200 Hz ~ 15 kHz versus 120 Hz ~ 17 kHz), and efficiency is higher at 95.00 dB versus 88.00 dB. Physical dimensions are comparable (77.00 mm x 77.00 mm versus 75.00 mm x 75.00 mm) with reduced height (30.50 mm versus 44.00 mm).

Parameter Comparison

Engineering Selection Recommendations

The GF0778B is an active product from CUI Devices with RoHS3 compliance, providing regulatory advantage over the obsolete AS07708PS-3-WR-R. Both parts share identical impedance, port orientation, and termination characteristics, establishing baseline electrical and mechanical compatibility.

Selection of the GF0778B requires evaluation of application power requirements. The substitute operates at 3 W rated power versus the original 10 W, representing a significant reduction in power handling capacity. Applications requiring the full 10 W power rating of the AS07708PS-3-WR-R cannot be directly substituted without circuit redesign.

The frequency response characteristics differ: the GF0778B begins at 200 Hz (versus 120 Hz) and extends to 15 kHz (versus 17 kHz). Applications requiring extended low-frequency response below 200 Hz or high-frequency extension above 15 kHz are not suitable for this substitution.

The GF0778B provides 7 dB higher efficiency (95.00 dB versus 88.00 dB), resulting in increased sound pressure level output at equivalent input power levels. The reduced seated height (30.50 mm versus 44.00 mm) may provide mechanical advantages in space-constrained enclosures.

Both parts maintain REACH compliance and EAR99 export classification. The GF0778B's active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the GF0778B directly replace the AS07708PS-3-WR-R in all applications?

A: Direct replacement is limited to applications where power requirements do not exceed 3 W rated operation. The AS07708PS-3-WR-R is rated at 10 W, and the GF0778B at 3 W. Applications utilizing the full power capacity of the original part require circuit redesign or alternative substitute selection.

Q: What are the impedance compatibility requirements?

A: Both parts operate at 8 Ohms. Impedance matching is maintained, and no circuit modifications are required for impedance compatibility.

Q: Are there mechanical fit considerations?

A: Both parts feature round, square frame construction with top-mounted ports. The GF0778B is slightly larger in lateral dimension (77.00 mm versus 75.00 mm) but significantly shorter in seated height (30.50 mm versus 44.00 mm). Enclosure design must accommodate these dimensional differences.

Q: How do frequency response characteristics affect substitution?

A: The GF0778B operates across 200 Hz to 15 kHz, while the AS07708PS-3-WR-R spans 120 Hz to 17 kHz. Applications requiring response below 200 Hz or above 15 kHz are not suitable for substitution with the GF0778B.

Q: What is the significance of the efficiency difference?

A: The GF0778B provides 95.00 dB efficiency versus 88.00 dB for the original part. This 7 dB difference represents approximately four times greater acoustic output at equivalent input power levels, resulting in higher sound pressure level generation.

Q: Are there compliance or regulatory differences?

A: Both parts maintain REACH compliance and EAR99 classification. The GF0778B carries RoHS3 compliance, providing regulatory advantage. The AS07708PS-3-WR-R is obsolete, while the GF0778B is an active product with ongoing manufacturer support.

Q: What termination compatibility exists?

A: Both parts utilize solder eyelet(s) termination, ensuring direct connection compatibility without adapter requirements.
