Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKB-10A is determined by strict equivalence across the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating: 125 VAC / 300 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Physical Dimensions: 0.280" Dia x 1.866" L (exact match required)
• Package / Case: Cylindrical, Alarm Indicating (exact match required)
• Breaking Capacity: 1kA (exact match required)
• Approval Certifications: CE, UR (must be maintained)
• RoHS Compliance: Required

The substitute part 70N-10A meets all these criteria and is manufactured by the same supplier, Eaton - Bussmann Electrical Division, within the same 70 series family.

Parameter Comparison

Engineering Selection Recommendations

The 70N-10A is the direct equivalent substitute for the obsolete GKB-10A. Both components are manufactured by Eaton - Bussmann Electrical Division within the 70 series and maintain identical electrical and mechanical specifications. The 70N-10A holds active product status, ensuring continued availability and supply chain support. Both parts carry CE and UR certifications and comply with RoHS requirements, meeting regulatory and compliance standards for telecom applications. The transition from GKB-10A to 70N-10A requires no circuit redesign or holder modification, as physical dimensions and electrical ratings are identical.

Frequently Asked Questions (FAQ)

Q: Can the 70N-10A be used as a direct replacement for the GKB-10A?

A: Yes. The 70N-10A is electrically and mechanically equivalent to the GKB-10A. Both components share identical current ratings (10A), voltage ratings (125 VAC / 300 VDC), physical dimensions (0.280" Dia x 1.866" L), breaking capacity (1kA), and holder mounting requirements. No circuit modifications are required.

Q: What is the primary difference between GKB-10A and 70N-10A?

A: The GKB-10A is classified as obsolete, while the 70N-10A is an active product. The 70N-10A is the current production equivalent within the Eaton 70 series family.

Q: Are both parts certified to the same standards?

A: Yes. Both the GKB-10A and 70N-10A carry CE and UR certifications and are RoHS compliant, meeting identical regulatory requirements for telecom applications.

Q: Does the packaging differ between these parts?

A: The GKB-10A is packaged individually, while the 70N-10A is supplied in bulk packaging. Both maintain the same cylindrical, alarm indicating case format and are compatible with the same holder assemblies.

Q: Are there any application restrictions when substituting the 70N-10A for the GKB-10A?

A: No. The 70N-10A is suitable for all applications where the GKB-10A was specified, including telecom systems requiring 10A protection at 125 VAC / 300 VDC with alarm indication capability.
