Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-V-15-R are classified based on strict electrical and mechanical parameter alignment. The substitution logic is structured as follows:

Direct Equivalent Classification: Parts classified as direct equivalents maintain identical specifications across all critical parameters: 15 A current rating, 250 V AC voltage rating, ceramic cartridge fuse type, 3AB/3AG package format, slow-blow response, through-hole mounting, 750 A breaking capacity, and RoHS3 compliance. These parts are interchangeable without circuit redesign or application re-evaluation.

Compatible Substitute Classification: Parts classified as compatible substitutes share the core electrical characteristics (15 A, 250 V AC, ceramic cartridge, slow-blow response, through-hole mounting, 3AB/3AG package) but may differ in secondary parameters such as DC voltage rating, breaking capacity, melting I²t value, or operating temperature range. These parts are suitable for applications where the differing parameters do not conflict with circuit requirements.

Key Parameters Determining Substitution:

• Current Rating: 15 A (mandatory match)
• Voltage Rating - AC: 250 V (mandatory match)
• Fuse Type: Cartridge, Ceramic (mandatory match)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (mandatory match)
• Response Time: Slow Blow (mandatory match)
• Mounting Type: Through Hole (mandatory match)

Parameter Comparison

Engineering Selection Recommendations

BK/MDA-V-15-R (Eaton - Electronics Division): This part is classified as a direct equivalent to the MDA-V-15-R. Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical and mechanical specifications, including 15 A current rating, 250 V AC voltage rating, 750 A breaking capacity, 336.82 melting I²t, and 0.00553 Ohms DC cold resistance. Both parts carry Active product status and hold CE, CSA, and UL certifications. Both are RoHS3 compliant. The BK/MDA-V-15-R designation represents a variant packaging or distribution channel designation within the same product family. This part is suitable for direct substitution in all applications where the MDA-V-15-R is specified.

0325015.MXP (Littelfuse Inc.): This part is classified as a compatible substitute. The 0325015.MXP shares the core electrical and mechanical characteristics with the MDA-V-15-R: 15 A current rating, 250 V AC voltage rating, ceramic cartridge fuse type, 3AB/3AG package format, slow-blow response, and through-hole mounting. Both parts are Active products with RoHS3 compliance and hold CE, CSA, and UL certifications. The 0325015.MXP differs in the following parameters: breaking capacity (400 A AC, 500 A DC versus 750 A), melting I²t (245 versus 336.82), DC cold resistance (0.005 Ohms versus 0.00553 Ohms), and specified operating temperature range (-55°C ~ 125°C). The 0325015.MXP also includes DC voltage rating (60 V) and additional certifications (K-MARK, PSE). This part is suitable for substitution in applications where the lower breaking capacity and melting I²t values do not conflict with circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-15-R be used as a direct replacement for MDA-V-15-R? A: Yes. The BK/MDA-V-15-R is a direct equivalent. Both parts are manufactured by Eaton - Electronics Division and maintain identical specifications across all critical electrical and mechanical parameters, including current rating, voltage rating, breaking capacity, melting I²t, and resistance values. No circuit modification is required.

Q: What are the key differences between MDA-V-15-R and 0325015.MXP? A: Both parts share identical current rating (15 A), AC voltage rating (250 V), fuse type (ceramic cartridge), package format (3AB/3AG), response time (slow-blow), and mounting type (through-hole). The 0325015.MXP differs in breaking capacity (400 A AC, 500 A DC versus 750 A), melting I²t (245 versus 336.82), DC cold resistance (0.005 Ohms versus 0.00553 Ohms), and includes a specified operating temperature range (-55°C ~ 125°C). The 0325015.MXP also includes DC voltage rating (60 V) and additional certifications (K-MARK, PSE).

Q: Is the 0325015.MXP suitable for all applications using MDA-V-15-R? A: The 0325015.MXP is suitable for applications where the lower breaking capacity (400 A AC, 500 A DC) and lower melting I²t value (245) do not conflict with circuit protection requirements. Applications requiring the full 750 A breaking capacity or higher melting I²t value of the MDA-V-15-R should not use the 0325015.MXP as a substitute.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The MDA-V-15-R, BK/MDA-V-15-R, and 0325015.MXP are all RoHS3 compliant.

Q: What certifications do these fuses hold? A: The MDA-V-15-R and BK/MDA-V-15-R hold CE, CSA, and UL certifications. The 0325015.MXP holds CE, CSA, K-MARK, PSE, and UL certifications.

Q: Are the physical dimensions identical across all three parts? A: The MDA-V-15-R and BK/MDA-V-15-R have identical dimensions (0.266" Dia x 1.292" L / 6.76mm x 32.82mm). The 0325015.MXP has slightly different dimensions (0.275" Dia x 1.288" L / 6.99mm x 32.72mm). Both package formats are 3AB/3AG and are mechanically compatible with standard through-hole fuse holders designed for this package type.

Q: What is the difference between the MDA-V-15-R and BK/MDA-V-15-R part numbers? A: Both parts are manufactured by Eaton - Electronics Division and are electrically and mechanically identical. The BK/ prefix designation represents a variant in packaging, distribution channel, or internal product classification. The parts are interchangeable.

Q: Can I use 0325015.MXP in a circuit designed for MDA-V-15-R if the breaking capacity is not a critical factor? A: The 0325015.MXP can be used in applications where the lower breaking capacity (400 A AC, 500 A DC) and lower melting I²t value (245) are acceptable for the circuit protection scheme. The core electrical characteristics (15 A, 250 V AC, slow-blow ceramic cartridge) are identical. Verify that the application does not require the higher breaking capacity or melting I²t value of the MDA-V-15-R before substitution.
