Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABC-V-25-R is determined by the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 25 A (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG format (exact match required)
• Mounting Type: Through Hole (exact match required)
• Voltage Rating - AC: 250 V minimum
• Voltage Rating - DC: 125 V minimum

Secondary Considerations:

• Breaking Capacity at rated voltage
• Melting I²t characteristics
• Physical dimensions (0.266" Dia x 1.292" L nominal)
• RoHS compliance status
• Regulatory approvals (CSA, UL, CE, cURus)

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical and mechanical specifications) and Functional Equivalents (same current and fuse type with equal or higher voltage ratings).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - BK/ABC-V-25-R (Eaton - Electronics Division)

The BK/ABC-V-25-R is a direct equivalent to the ABC-V-25-R with identical electrical specifications (25 A, 250 V AC, 125 V DC), fuse type, package format, and breaking capacity. Both parts carry CSA and UL approvals and are ROHS3 compliant. This substitute provides seamless interchangeability with higher inventory availability (1973 units in stock). Selection of this part introduces no technical risk and maintains full compliance with the original design specifications.

Functional Equivalent - 0324025.MXP (Littelfuse Inc.)

The 0324025.MXP meets the core substitution criteria with matching current rating (25 A), voltage ratings (250 V AC, 125 V DC), fuse type, and package format. Physical dimensions are within tolerance (0.275" Dia vs. 0.266" Dia). This part carries expanded regulatory approvals (CE, K-MARK, PSE, UL) and specifies operating temperature range (-55°C ~ 125°C). The breaking capacity at rated AC voltage is reduced to 100A (versus 200A for the main part), and melting I²t is elevated to 1450. This part is suitable for applications where the lower AC breaking capacity does not conflict with circuit protection requirements. Inventory availability is significantly higher (10532 units in stock).

Functional Equivalent with Elevated Voltage Rating - 0504025.MXEP (Littelfuse Inc.)

The 0504025.MXEP maintains the 25 A current rating and 3AB/3AG package format but provides elevated voltage ratings (500 V AC, 420 V DC). This part is suitable only for applications where the circuit operates at or below the original voltage specifications (250 V AC, 125 V DC) and where the higher voltage rating does not introduce design conflicts. The part carries CE and cURus approvals, specifies operating temperature range (-55°C ~ 125°C), and has the highest inventory availability (30368 units in stock). Selection of this part for circuits designed for 250 V AC / 125 V DC operation introduces no functional risk, as the fuse will operate within its rated envelope.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-25-R be used as a direct replacement for ABC-V-25-R?

A: Yes. The BK/ABC-V-25-R is a direct equivalent with identical current rating (25 A), voltage ratings (250 V AC, 125 V DC), fuse type (Cartridge, Ceramic), package format (3AB, 3AG), and breaking capacity (200A AC, 400A DC). Both parts are manufactured by Eaton - Electronics Division and carry CSA and UL approvals. No design modifications are required.

Q: What is the difference between the Littelfuse 0324025.MXP and the Eaton ABC-V-25-R?

A: The 0324025.MXP matches the ABC-V-25-R in current rating, voltage ratings, fuse type, and package format. Key differences include: (1) physical diameter is 0.275" versus 0.266", (2) breaking capacity at rated AC voltage is 100A versus 200A, (3) melting I²t is 1450 versus 839.3, and (4) regulatory approvals include CE, K-MARK, and PSE in addition to UL. The part is suitable for applications where the lower AC breaking capacity is acceptable.

Q: When should the 0504025.MXEP be selected instead of the ABC-V-25-R?

A: The 0504025.MXEP should be selected when circuit design requires elevated voltage ratings (500 V AC, 420 V DC) or when the higher voltage rating provides system-level benefits. For circuits designed for 250 V AC / 125 V DC operation, the 0504025.MXEP operates safely within its rated envelope and provides equivalent protection. The elevated voltage rating does not degrade performance in lower-voltage applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The ABC-V-25-R, BK/ABC-V-25-R, 0324025.MXP, and 0504025.MXEP are all ROHS3 compliant and REACH unaffected.

Q: What are the physical dimension tolerances for package compatibility?

A: The ABC-V-25-R specifies 0.266" Dia x 1.292" L (6.76mm x 32.82mm). The Littelfuse parts (0324025.MXP and 0504025.MXEP) specify 0.275" Dia x 1.288" L (6.99mm x 32.72mm). The diameter difference is 0.009" (0.23mm) and the length difference is 0.004" (0.10mm). These variations are within standard 3AB/3AG package tolerances and do not affect mechanical fit in standard fuse holders.

Q: Which substitute part has the best inventory availability?

A: The 0504025.MXEP has the highest inventory availability with 30368 units in stock, followed by 0324025.MXP with 10532 units, BK/ABC-V-25-R with 1973 units, and ABC-V-25-R with 684 units.

Q: Do all substitute parts have the same response time (Fast Blow)?

A: The ABC-V-25-R, BK/ABC-V-25-R, and 0324025.MXP are specified as Fast Blow. The 0504025.MXEP does not specify response time in the provided data.
