BK/MDA-V-1-R Equivalent & Substitute Parts

Part Overview

The BK/MDA-V-1-R is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated at 1 A, 250 V AC, with slow-blow response characteristics. This through-hole mounted fuse is designed for applications requiring overcurrent protection in AC circuits. The part is currently active in production with 751 pieces in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative components that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/MDA-V-1-R is permissible with components that maintain the following critical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (minimum requirement)
• Fuse Type: Cartridge, Ceramic (form factor and material)
• Response Time: Slow Blow (thermal response characteristic)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (mechanical compatibility)
• Mounting Type: Through Hole (circuit board integration)
• Approval Agency: Compliance with CE, CSA, and/or UL standards

The substitute part 0325001.HXP from Littelfuse Inc. satisfies all critical substitution criteria. This part maintains identical current and AC voltage ratings, ceramic cartridge construction, slow-blow response, and compatible package dimensions. The substitute additionally provides DC voltage rating (125 V DC) and enhanced breaking capacity, which do not conflict with the original specification and may provide additional design flexibility.

Parameter Comparison

Engineering Selection Recommendations

The 0325001.HXP from Littelfuse Inc. is a direct substitute for the BK/MDA-V-1-R. Both components are active products with current manufacturing status and full RoHS3 compliance. The substitute part meets or exceeds all critical electrical parameters required for the original application.

Selection between these two parts should be based on:

• Availability: Both parts are in stock (751 pcs for BK/MDA-V-1-R; 896 pcs for 0325001.HXP)
• Regulatory Compliance: Both parts carry CE, CSA, and UL certifications, meeting international safety standards
• Environmental Specifications: The Littelfuse part specifies operating temperature range (-55°C ~ 125°C) and MSL rating (1 - Unlimited), providing additional environmental documentation
• Supply Chain Continuity: The Littelfuse part offers enhanced breaking capacity and DC voltage rating, which may provide design margin in applications requiring future flexibility

No technical barriers exist to substituting 0325001.HXP for BK/MDA-V-1-R in circuits designed for the original component.

Frequently Asked Questions (FAQ)

Q: Can 0325001.HXP be used as a direct replacement for BK/MDA-V-1-R?

A: Yes. Both components share identical current rating (1 A), AC voltage rating (250 V), ceramic cartridge construction, slow-blow response, and 3AB/3AG package dimensions. The substitute part is mechanically and electrically compatible for through-hole mounting applications.

Q: What is the difference in breaking capacity between these two fuses?

A: The BK/MDA-V-1-R has a breaking capacity of 35 A at rated voltage. The 0325001.HXP has a breaking capacity of 100 A AC and 10 kA DC. The higher breaking capacity of the substitute part does not create incompatibility; it indicates enhanced fault current handling capability.

Q: Does the Littelfuse part provide DC voltage rating while the Eaton part does not?

A: The 0325001.HXP is rated for 125 V DC in addition to 250 V AC. The BK/MDA-V-1-R specification does not include a DC voltage rating. If the application requires DC circuit protection, the Littelfuse part provides this additional capability. If the application is AC-only, both parts are suitable.

Q: Are the physical dimensions identical?

A: The dimensions are equivalent for practical mounting purposes. BK/MDA-V-1-R: 0.266" Dia x 1.292" L (6.76mm x 32.82mm). 0325001.HXP: 0.275" Dia x 1.288" L (6.99mm x 32.72mm). Both conform to the 3AB, 3AG, 1/4" x 1-1/4" (Axial) package standard and are compatible with standard fuse holders designed for this form factor.

Q: What certifications do both parts carry?

A: BK/MDA-V-1-R carries CE, CSA, and UL certifications. 0325001.HXP carries CE, CSA, PSE, and UL certifications. Both parts meet the primary international safety standards required for industrial and commercial applications.

Q: Is there a difference in DC cold resistance?

A: BK/MDA-V-1-R: 0.38 Ohms. 0325001.HXP: 0.389 Ohms. The difference is negligible (0.009 Ohms) and does not affect circuit performance or fuse operation.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BK/MDA-V-1-R and 0325001.HXP are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.
