GF1007C Equivalent & Substitute Parts

Part Overview

The GF1007C is an 8 Ohm general purpose speaker rated at 10 W with a top-mounted round port configuration. Manufactured by CUI Devices, this component operates across a frequency range of 120 Hz to 10 kHz and delivers 92 dB SPL at 1W/500mm. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GF1007C is determined by the following critical parameters:

• Impedance Match: 8 Ohms (electrical compatibility with existing circuits)
• Port Location: Top-mounted configuration (mechanical fit within enclosure constraints)
• Termination Type: Solder Eyelet(s) (connection method compatibility)
• Material Composition: Paper cone and ferrite magnet (acoustic and thermal characteristics)
• Frequency Range Overlap: Minimum coverage of the 120 Hz to 10 kHz band
• Regulatory Compliance: RoHS compliance status for environmental standards

The GF1004H qualifies as a substitute based on matching impedance, port location, termination type, material composition, and regulatory compliance. Differences in power rating, efficiency, and dimensional specifications reflect design variations within the compatible parameter set.

Parameter Comparison

Engineering Selection Recommendations

The GF1004H serves as the primary substitute for the obsolete GF1007C. Both components maintain identical impedance (8 Ohms), port location (top), termination method (solder eyelet), and core material specifications (paper cone, ferrite magnet), ensuring electrical and mechanical compatibility.

The GF1004H is currently in active production status with ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs. The substitute exhibits an extended lower frequency response (100 Hz versus 120 Hz) and broader frequency range coverage (100 Hz ~ 10 kHz), supporting applications requiring enhanced bass reproduction.

Dimensional differences require verification against enclosure specifications. The GF1004H measures 4.016" x 4.016" (102mm x 102mm) with a maximum seated height of 2.008" (51mm), compared to the GF1007C's 3.937" diameter (100mm) and 1.850" height (47mm). The GF1004H offers dual shape options (round and square frame), providing mounting flexibility.

Power rating elevation (20 W rated, 40 W maximum versus 10 W rated, 15 W maximum) permits operation at higher acoustic output levels without thermal stress. Efficiency specification of 90 dB SPL represents a 2 dB reduction relative to the GF1007C, reflecting the acoustic characteristics of the higher-power design.

Frequently Asked Questions (FAQ)

Q: Can the GF1004H directly replace the GF1007C in existing designs?

A: Electrical compatibility is confirmed through matching impedance (8 Ohms) and termination type (solder eyelet). Mechanical fit requires validation against enclosure dimensions, as the GF1004H is slightly larger (102mm x 102mm versus 100mm diameter) and taller (51mm versus 47mm seated height).

Q: What are the key differences between these two speakers?

A: The GF1004H provides double the rated power capacity (20 W versus 10 W) and extended lower frequency response (100 Hz versus 120 Hz). The GF1007C delivers 2 dB higher efficiency (92 dB SPL versus 90 dB SPL). Both maintain identical impedance, port location, and material composition.

Q: Why is the GF1007C obsolete?

A: The GF1007C is listed as obsolete by the manufacturer. The GF1004H represents the active production alternative within the CUI Devices GF series general purpose speaker line.

Q: Are there packaging differences between these components?

A: The GF1007C is supplied without specified packaging designation. The GF1004H is packaged in boxes. Confirm packaging requirements with procurement specifications.

Q: Do both speakers meet current regulatory standards?

A: The GF1007C carries RoHS Compliant status. The GF1004H meets the more recent ROHS3 Compliant standard and is REACH Unaffected, providing enhanced regulatory alignment for current manufacturing environments.

Q: What is the impact of the efficiency difference on system design?

A: The GF1007C produces 92 dB SPL at 1W/500mm, while the GF1004H produces 90 dB SPL under identical test conditions. This 2 dB difference reflects acoustic design trade-offs associated with the higher power rating. System amplifier output may require adjustment to achieve equivalent sound pressure levels.
