Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for BK1/ABC-10-R is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

• Current Rating: 10 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)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below satisfy these mandatory criteria. Variations in secondary parameters such as DC Cold Resistance, Melting I²t, Breaking Capacity, and RoHS compliance status do not disqualify substitution eligibility when primary electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Eaton ABC Series (Active Status):

ABC-10-R and BK/ABC-10-R are direct parametric equivalents to BK1/ABC-10-R with identical electrical specifications, mechanical dimensions, and breaking capacity ratings. Both parts maintain active product status and ROHS3 compliance. These parts are preferred for applications requiring exact specification matching within the Eaton ABC series family.

Secondary Recommendation - Eaton ABC Series (Alternative Variants):

BK1/ABC-10DX-R provides identical parametric specifications to the main part with active product status and ROHS3 compliance. This variant is suitable for direct substitution in all applications.

Alternative Recommendation - Eaton GBB Series:

BK/GBB-10-R and GBB-10-R are parametrically equivalent across all mandatory criteria. These parts feature lower DC cold resistance (0.00934 Ohms versus 0.011 Ohms) and maintain active product status with ROHS3 compliance. Selection of GBB series parts is appropriate when secondary parameter variations are acceptable.

Cross-Manufacturer Recommendation - Littelfuse 314 Series:

0314010.HXP, 0314010.MXANP, 0314010.MXP, and 0314010.VXP are parametrically equivalent ceramic cartridge fuses from Littelfuse Inc. These parts satisfy all mandatory electrical and mechanical specifications. The Littelfuse 314 series offers higher breaking capacity (750A AC versus 200A AC) and extended operating temperature range (-55°C to 125°C). All Littelfuse variants maintain active product status and ROHS3 compliance.

Compliance Consideration:

BK/ABC-B-10 is parametrically equivalent but carries RoHS non-compliant status. Selection of this part is restricted to applications where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can BK1/ABC-10-R be directly replaced with ABC-10-R or BK/ABC-10-R?

A: Yes. ABC-10-R and BK/ABC-10-R are direct parametric equivalents with identical current rating (10 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package configuration (3AB/3AG), and physical dimensions (0.250" Dia x 1.250" L). Both parts are compatible with the same holder configurations and mounting systems.

Q: What is the difference between Eaton ABC series and GBB series substitutes?

A: Both series maintain identical mandatory electrical and mechanical specifications. The primary difference is DC cold resistance: ABC series parts measure 0.011 Ohms while GBB series parts measure 0.00934 Ohms. This variation does not affect substitution eligibility. Breaking capacity specifications differ slightly, with GBB-10-R and BK/GBB-10-R specifying 10kA DC only, while ABC series parts specify 200A AC and 10kA DC.

Q: Are Littelfuse 314 series fuses compatible with Eaton ABC series holders?

A: Yes. Littelfuse 0314010.HXP, 0314010.MXANP, 0314010.MXP, and 0314010.VXP maintain identical package configuration (3AB, 3AG) and physical dimensions (0.250" Dia x 1.250" L) as BK1/ABC-10-R. These parts are mechanically and electrically compatible with all 3AB/3AG holder systems.

Q: What is the significance of the higher breaking capacity in Littelfuse parts?

A: Littelfuse 314 series parts specify 750A AC breaking capacity compared to 200A AC in Eaton ABC series. Breaking capacity indicates the maximum fault current the fuse can safely interrupt. Higher breaking capacity provides additional safety margin in high-fault-current applications but does not affect substitution eligibility when all other parameters match.

Q: Should I select ROHS3 compliant parts over RoHS non-compliant alternatives?

A: ROHS3 compliance status is determined by application requirements and regulatory jurisdiction. All recommended primary substitutes (ABC-10-R, BK/ABC-10-R, BK1/ABC-10DX-R, GBB series, and Littelfuse 314 series) are ROHS3 compliant. BK/ABC-B-10 is RoHS non-compliant and should be selected only when RoHS compliance is not a system requirement.

Q: What is the operating temperature range for each substitute?

A: Eaton ABC and GBB series parts do not specify operating temperature limits in the provided data. Littelfuse 314 series parts operate across -55°C to 125°C. For applications requiring extended temperature operation, Littelfuse 314 series parts provide documented temperature specifications.

Q: Are there inventory considerations when selecting substitutes?

A: Current inventory levels vary across substitute parts. BK/ABC-10-R maintains the highest Eaton inventory (3104 Pcs), while 0314010.MXP maintains the highest overall inventory (5887 Pcs). Inventory status should be verified at time of procurement to ensure supply continuity.
