Equivalent & Substitute Parts for ABC-9-R Ceramic Cartridge Fuse

Part Overview

The ABC-9-R is a 9 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation, manufactured by Eaton - Electronics Division. This component is classified as obsolete and requires a compatible fuse holder (3AB, 3AG format, 1/4" x 1-1/4"). Due to its obsolete product status, equivalent substitute parts from the active GBB series are available to maintain circuit protection functionality in applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ABC-9-R is based on strict equivalence of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Current Rating: 9 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)

The GBB series parts (GBB-9-R and BK/GBB-9-R) satisfy all critical substitution parameters and are classified as active products. Both substitute parts maintain identical electrical performance and mechanical compatibility with the original ABC-9-R specification.

Parameter Comparison

Engineering Selection Recommendations

GBB-9-R is the primary substitute for the obsolete ABC-9-R. This part is manufactured by Eaton - Electronics Division and holds active product status. It meets all electrical and mechanical requirements specified for the ABC-9-R, including current rating, voltage ratings, fuse type, response time, and physical dimensions. The GBB-9-R carries CSA and UR approvals and is ROHS3 compliant. Inventory availability is 1107 pieces.

BK/GBB-9-R is an alternative substitute available in bulk packaging. This part is functionally equivalent to GBB-9-R and ABC-9-R across all critical electrical and mechanical parameters. It carries the same regulatory approvals (CSA, UR) and RoHS compliance status. Inventory availability is 812 pieces.

Both substitute parts are direct replacements for the ABC-9-R in applications requiring 9 A ceramic cartridge fuses with 250 V AC / 125 V DC ratings and fast-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can GBB-9-R and BK/GBB-9-R be used interchangeably with ABC-9-R?

A: Yes. Both GBB-9-R and BK/GBB-9-R are direct electrical and mechanical equivalents to ABC-9-R. They share identical current ratings (9 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and physical dimensions (0.250" Dia x 1.250" L). Both fit standard 3AB and 3AG fuse holders.

Q: What is the difference between GBB-9-R and BK/GBB-9-R?

A: The primary difference is packaging. GBB-9-R is supplied in standard packaging, while BK/GBB-9-R is supplied in bulk packaging. Electrically and mechanically, both parts are identical and meet the same specifications.

Q: Why is ABC-9-R listed as obsolete?

A: ABC-9-R has been discontinued by the manufacturer. The GBB series represents the current active product line for equivalent 9 A ceramic cartridge fuses from Eaton - Electronics Division.

Q: Are the regulatory approvals the same between ABC-9-R and the substitute parts?

A: ABC-9-R carries CSA and UL approvals. The substitute parts (GBB-9-R and BK/GBB-9-R) carry CSA and UR approvals. Both approval sets are recognized standards for fuse certification.

Q: Will the substitute parts fit in existing ABC-9-R fuse holders?

A: Yes. Both GBB-9-R and BK/GBB-9-R maintain the same physical dimensions (0.250" Dia x 1.250" L) and are compatible with 3AB and 3AG fuse holder formats.

Q: What is the DC cold resistance specification?

A: GBB-9-R and BK/GBB-9-R both specify 0.0107 Ohms DC cold resistance. This specification was not provided for the original ABC-9-R.

Q: What breaking capacity do the substitute parts provide?

A: GBB-9-R provides 200A AC and 10kA DC breaking capacity. BK/GBB-9-R provides 10kA breaking capacity. Breaking capacity specifications were not provided for the original ABC-9-R.
