Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/ABC-BV-30-R is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 30 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)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Parametric Equivalent Classification: The part BK/ABC-V-30-R qualifies as a parametric equivalent. This part is manufactured by the same supplier (Eaton - Electronics Division) and maintains identical electrical ratings, fuse characteristics, package dimensions, and mounting configuration. All critical parameters align with the main part specification.

Direct Manufacturer Part Classification: The part 0504030.MXEP is classified as a direct manufacturer part from Littelfuse Inc. This part shares the same current rating (30 A), package form factor (3AB, 3AG, 1/4" x 1-1/4"), and mounting type (Through Hole). However, this part operates at higher voltage ratings (500 V AC, 420 V DC) and exhibits different thermal characteristics (Melting I²t: 2600 versus 1429). This part is suitable only for applications where the higher voltage rating is compatible with the circuit design.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): The BK/ABC-V-30-R is the recommended parametric equivalent for the BK/ABC-BV-30-R. Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical specifications, thermal characteristics, and dimensional tolerances. Both parts carry CSA and UL approvals and ROHS3 compliance. This part provides seamless interchangeability with no circuit design modifications required. Current inventory of 2956 pieces supports immediate availability.

For Higher Voltage Applications (Direct Manufacturer Part): The 0504030.MXEP from Littelfuse Inc. is suitable only when circuit design requirements permit operation at 500 V AC and 420 V DC. This part is not a direct replacement for the BK/ABC-BV-30-R due to voltage rating differences. The higher Melting I²t value (2600 versus 1429) and increased DC cold resistance (0.0031 versus 0.002225 Ohms) indicate different thermal response characteristics. This part carries CE and cURus approvals with specified operating temperature range of -55°C to 125°C. Selection of this part requires circuit-level validation to confirm voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-30-R be used as a direct replacement for BK/ABC-BV-30-R? A: Yes. The BK/ABC-V-30-R is a parametric equivalent with identical current rating (30 A), AC voltage rating (250 V), DC voltage rating (125 V), fuse type (Cartridge, Ceramic), package form (3AB, 3AG, 1/4" x 1-1/4"), and mounting configuration (Through Hole). Both parts are manufactured by Eaton - Electronics Division and carry the same approvals (CSA, UL).

Q: What are the limitations of using 0504030.MXEP as a substitute? A: The 0504030.MXEP operates at higher voltage ratings (500 V AC, 420 V DC) compared to the BK/ABC-BV-30-R (250 V AC, 125 V DC). While the current rating and package dimensions are compatible, the different voltage ratings and thermal characteristics (Melting I²t: 2600 versus 1429) require circuit-level validation before substitution. This part is suitable only for applications designed for higher voltage operation.

Q: Are there dimensional compatibility concerns with 0504030.MXEP? A: The 0504030.MXEP has slightly different dimensions (0.275" Dia x 1.288" L versus 0.266" Dia x 1.292" L). Both parts use the 3AB, 3AG, 1/4" x 1-1/4" package designation and through-hole mounting. The minor dimensional variation should be evaluated against specific mechanical mounting constraints in the application.

Q: What approval agencies certify these parts? A: The BK/ABC-BV-30-R and BK/ABC-V-30-R carry CSA and UL approvals. The 0504030.MXEP carries CE and cURus approvals. Selection should align with regional regulatory requirements for the end application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All three parts (BK/ABC-BV-30-R, BK/ABC-V-30-R, and 0504030.MXEP) are ROHS3 compliant and REACH unaffected.
