Equivalent & Substitute Parts for BK/ABC-V-15-R Ceramic Fuse Cartridge

Part Overview

The BK/ABC-V-15-R is a 15 A ceramic fuse cartridge manufactured by Eaton - Electronics Division, rated for 250 V AC and 125 V DC operation. This through-hole mounted component features fast-blow response characteristics and is designed for applications requiring reliable overcurrent protection in industrial and commercial equipment. The part maintains active product status with 1041 units in current inventory stock.

Substitute parts become necessary when primary component availability is limited, when supply chain optimization requires alternative sourcing, or when design flexibility permits equivalent electrical and mechanical specifications from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ceramic fuse cartridges is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

Electrical Equivalence Requirements:

• Current Rating: 15 A (exact match)
• Voltage Rating - AC: 250 V (exact match)
• Voltage Rating - DC: 125 V (exact match)
• Response Time: Fast Blow (exact match)
• Breaking Capacity @ Rated Voltage: 750 A AC, 10 kA DC (exact match)

Mechanical Equivalence Requirements:

• Fuse Type: Cartridge, Ceramic (exact match)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match)
• Mounting Type: Through Hole (exact match)

Compliance Requirements:

• RoHS3 Compliant status
• Regulatory approval from recognized agencies (CSA, UL, or equivalent)

Both substitute parts listed below satisfy all electrical, mechanical, and compliance criteria for direct substitution with BK/ABC-V-15-R.

Parameter Comparison

Engineering Selection Recommendations

Both Littelfuse substitute parts (0324015.HXP and 0324015.MXP) are qualified equivalents to the Eaton BK/ABC-V-15-R based on matching electrical specifications, mechanical form factor, and regulatory compliance.

Compliance Considerations:

The Littelfuse parts carry expanded approval certifications (CE, CSA, K-MARK, UL) compared to the Eaton part (CSA, UL). This expanded certification scope does not create incompatibility; rather, it indicates broader regulatory acceptance across additional markets and standards bodies.

Inventory and Availability:

The Littelfuse 0324015.MXP offers the highest current inventory level at 20,400 units, followed by 0324015.HXP at 9,290 units. The Eaton BK/ABC-V-15-R maintains 1,041 units in stock. Selection between substitute parts may be driven by supply chain logistics and procurement lead times.

Dimensional and Electrical Tolerance:

Minor dimensional variations exist within the specified 3AB, 3AG package envelope. The Littelfuse parts measure 0.275" diameter × 1.288" length compared to the Eaton part at 0.266" diameter × 1.292" length. These variations remain within standard package tolerances for through-hole mounting applications. DC cold resistance values differ slightly (0.00505 Ohms for Littelfuse versus 0.00553 Ohms for Eaton), with no functional impact on circuit protection performance.

All three parts are active products with established supply chains and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can 0324015.HXP and 0324015.MXP be used interchangeably with BK/ABC-V-15-R?

A: Yes. Both Littelfuse parts meet all electrical and mechanical substitution criteria. They share identical current ratings (15 A), voltage ratings (250 V AC, 125 V DC), response characteristics (fast blow), package specifications (3AB, 3AG, 1/4" × 1-1/4"), and breaking capacity (750 A AC, 10 kA DC). All three parts are ROHS3 compliant and carry recognized regulatory approvals.

Q: What is the difference between 0324015.HXP and 0324015.MXP?

A: Both parts are manufactured by Littelfuse and share identical electrical and mechanical specifications. The primary differences are inventory availability (0324015.MXP: 20,400 units; 0324015.HXP: 9,290 units) and melting I²t values (0324015.MXP and 0324015.HXP: 292 versus BK/ABC-V-15-R: 200.2). The I²t difference reflects manufacturing process variations within the fast-blow ceramic fuse category and does not affect substitution eligibility for standard 15 A protection applications.

Q: Are there dimensional compatibility concerns with through-hole mounting?

A: No. The Littelfuse parts measure 0.275" diameter × 1.288" length, compared to the Eaton part at 0.266" diameter × 1.292" length. Both dimensions fall within the 3AB, 3AG standard package envelope and are compatible with standard through-hole fuse holders and sockets designed for this package class.

Q: Do the expanded certifications on Littelfuse parts (CE, K-MARK) affect compatibility?

A: No. Expanded certifications indicate broader regulatory acceptance and do not create incompatibility. The Littelfuse parts retain all certifications held by the Eaton part (CSA, UL) and add additional market approvals. This represents equivalent or superior compliance standing.

Q: What is the significance of the DC cold resistance difference?

A: DC cold resistance values (Eaton: 0.00553 Ohms; Littelfuse: 0.00505 Ohms) reflect minor manufacturing variations in ceramic fuse element construction. These differences are within acceptable tolerances for fast-blow ceramic cartridge fuses and do not impact circuit protection performance or substitution eligibility.

Q: Can these parts be used in applications requiring specific I²t characteristics?

A: The melting I²t values differ between manufacturers (Eaton BK/ABC-V-15-R: 200.2; Littelfuse 0324015.HXP and 0324015.MXP: 292). Applications with strict I²t requirements should confirm compatibility with circuit design specifications. For standard overcurrent protection applications, both values are acceptable for 15 A fast-blow protection.
