• 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" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Acceptable Variation Parameters:

• DC Cold Resistance: Minor variations within 0.004–0.0055 Ohms range
• Breaking Capacity: Variations permitted (750A AC minimum, 10kA DC minimum)
• Melting I²t: Variations permitted within manufacturer specifications

• Product Status: Active status preferred over obsolete

All substitute parts listed maintain identical electrical performance and mechanical fit within the specified tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Eaton ABC Series - Direct Lineage):

ABC-V-15-R and BK/ABC-V-15-R are the preferred direct replacements for BK/ABC-V-15. Both parts maintain identical electrical specifications, mechanical dimensions, and breaking capacity ratings. These parts are active products with ROHS3 compliance, ensuring regulatory alignment and extended lifecycle support. The ABC series maintains design continuity with the original obsolete part.

Secondary Substitutes (Eaton GBB Series - Parametric Equivalent):

BK/GBB-V-15-R and GBB-V-15-R are parametric equivalents from the Eaton GBB series. These parts meet all mandatory electrical and mechanical criteria. The GBB series offers lower DC cold resistance (0.00472 Ohms versus 0.005425 Ohms), which may provide marginal performance benefits in DC applications. Both parts carry ROHS3 compliance and active product status.

Tertiary Substitutes (Littelfuse 324 Series - Cross-Manufacturer Equivalent):

0324015.HXP, 0324015.MXP, and 0324015.VXP are Littelfuse 324 series alternatives. These parts satisfy all mandatory substitution criteria with identical current, voltage, and package specifications. The Littelfuse parts feature expanded approval agency certifications (CE, CSA, K-MARK, UL for HXP/MXP; CE, CSA, KC, PSE, UL for VXP) and specified operating temperature range (-55°C to 125°C). ROHS3 compliance and active product status are confirmed. The 0324015.MXP variant offers the highest inventory availability (20,400 pieces).

Selection Priority:

1. ABC-V-15-R or BK/ABC-V-15-R for design continuity within Eaton ABC series
2. BK/GBB-V-15-R or GBB-V-15-R for Eaton platform standardization with enhanced DC performance
3. 0324015.MXP for maximum supply chain availability and cross-manufacturer flexibility

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-15 be directly replaced with ABC-V-15-R?

A: Yes. ABC-V-15-R is a direct substitute. Both parts share identical current rating (15 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB/3AG), and breaking capacity (750A AC / 10kA DC). ABC-V-15-R is active and ROHS3 compliant, addressing the obsolete status of BK/ABC-V-15.

Q: What is the difference between ABC-V-15-R and BK/ABC-V-15-R?

A: Both parts are electrically and mechanically identical. The primary difference is packaging designation. ABC-V-15-R uses bulk packaging, while BK/ABC-V-15-R also uses bulk packaging. Both are active Eaton products with ROHS3 compliance and equivalent DC cold resistance (0.00553 Ohms).

Q: Are Littelfuse 0324015 series parts compatible with Eaton ABC fuses?

A: Yes. The Littelfuse 0324015.HXP, 0324015.MXP, and 0324015.VXP parts are parametric equivalents meeting all mandatory substitution criteria: 15 A current rating, 250 V AC / 125 V DC voltage ratings, ceramic cartridge type, fast blow response, 3AB/3AG package, and through-hole mounting. Mechanical dimensions are within acceptable tolerance (0.275" Dia x 1.288" L for Littelfuse versus 0.266" Dia x 1.292" L for Eaton). All three Littelfuse variants are active products with ROHS3 compliance.

Q: What is the significance of DC cold resistance variation among substitutes?

A: DC cold resistance values range from 0.00472 Ohms (GBB series) to 0.00553 Ohms (ABC-R series) to 0.00505 Ohms (Littelfuse 324 series). These variations fall within acceptable engineering tolerance for ceramic cartridge fuses and do not affect functional performance in standard circuit protection applications. Lower resistance values may provide marginal benefits in high-current DC circuits, but all values are within manufacturer specifications.

Q: Which substitute offers the best supply chain availability?

A: Littelfuse 0324015.MXP provides the highest inventory availability at 20,400 pieces. This variant is recommended for applications requiring immediate procurement or high-volume requirements. The part maintains full electrical and mechanical equivalence with BK/ABC-V-15.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (ABC-V-15-R, BK/ABC-V-15-R, BK/ABC-BV-15-R, BK/GBB-V-15-R, GBB-V-15-R, 0324015.HXP, 0324015.MXP, 0324015.VXP) are ROHS3 compliant. The original BK/ABC-V-15 is RoHS non-compliant, making substitution necessary for regulatory alignment.

Q: Can GBB series fuses be used interchangeably with ABC series fuses?

A: Yes, within the specified parameters. BK/GBB-V-15-R and GBB-V-15-R are parametric equivalents to BK/ABC-V-15. Both maintain identical current, voltage, package, and mounting specifications. The GBB series offers lower DC cold resistance and active product status. Both series are manufactured by Eaton and carry appropriate certifications (CSA, UL for ABC; CSA, UR for GBB).

Q: What approval agencies certify these fuse products?

A: Eaton ABC series parts carry CSA and UL certifications. Eaton GBB series parts carry CSA and UR certifications. Littelfuse 324 series parts carry expanded certifications: CE, CSA, K-MARK, and UL (0324015.HXP and 0324015.MXP); CE, CSA, KC, PSE, and UL (0324015.VXP). All certifications meet or exceed the original BK/ABC-V-15 approval requirements.

Q: Is mechanical dimension variation between Eaton and Littelfuse parts significant?

A: Dimension variation is minimal and acceptable. Eaton parts measure 0.266" Dia x 1.292" L (6.76mm x 32.82mm). Littelfuse parts measure 0.275" Dia x 1.288" L (6.99mm x 32.72mm). Both conform to 3AB/3AG package standards and fit standard through-hole fuse holders designed for this package format. No mechanical incompatibility exists.
