GFA-8 Board Mount Fuse Equivalent & Substitute Parts

Part Overview

The GFA-8 is a board mount fuse manufactured by Eaton - Electronics Division, rated for 8 A at 32 V AC/DC with fast blow response characteristics. This component is designed for through-hole mounting applications using a cartridge, non-standard (axial) package configuration. The part maintains active product status with 645 units currently in stock.

Identifying equivalent and substitute parts is necessary when addressing supply chain requirements, design revisions, or when alternative sourcing options with enhanced compliance certifications are required.

Substitute Part Grouping Explanation

Substitution eligibility for the GFA-8 is determined by strict equivalence across the following critical parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating: 32 V AC (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Physical Dimensions: 0.146" Dia x 0.299" L / 3.70mm x 7.60mm (exact match required)
• Breaking Capacity: 50 A (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute part BK/GFA-8 meets all electrical and mechanical parameters required for direct substitution. Additional differentiation exists in compliance certifications and RoHS status, which may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both GFA-8 and BK/GFA-8 are electrically and mechanically equivalent for applications requiring an 8 A, 32 V AC/DC fast blow board mount fuse in axial cartridge configuration.

Selection between these parts should be based on the following criteria:

GFA-8: Select this part number when RoHS compliance is not a design requirement and approval agency certifications are not mandated by application specifications.

BK/GFA-8: Select this part number when designs require RoHS compliance or when CSA and UL approval agency certifications are specified. This variant provides enhanced regulatory alignment for applications subject to environmental or safety standards.

Both parts maintain identical electrical performance, physical dimensions, and breaking capacity characteristics. Inventory availability is comparable between both options.

Frequently Asked Questions (FAQ)

Q: Can BK/GFA-8 be used as a direct replacement for GFA-8 in existing designs?

A: Yes. BK/GFA-8 is a parametric equivalent with identical electrical ratings (8 A, 32 V AC/DC), response time (fast blow), physical dimensions (0.146" Dia x 0.299" L), and breaking capacity (50 A). Both use through-hole mounting with cartridge, non-standard (axial) packaging. Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the primary difference between GFA-8 and BK/GFA-8?

A: The primary differences are RoHS compliance status and approval agency certifications. BK/GFA-8 is RoHS compliant and carries CSA and UL approvals, while GFA-8 is RoHS non-compliant with no listed approval agencies. Electrical and mechanical specifications are identical.

Q: Are there any dimensional or mounting differences between these parts?

A: No. Both parts share identical physical dimensions of 0.146" Dia x 0.299" L (3.70mm x 7.60mm) and use the same through-hole mounting configuration with cartridge, non-standard (axial) package type.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. If RoHS compliance or CSA/UL certifications are required, specify BK/GFA-8. If these certifications are not mandated, either part is suitable based on availability and cost considerations.

Q: Do both parts have the same breaking capacity?

A: Yes. Both GFA-8 and BK/GFA-8 have a breaking capacity of 50 A at rated voltage, ensuring equivalent protection performance in circuit applications.
