Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/MDA-V-2-R is determined by the following critical parameters:

Current Rating: 2 A (exact match required)

Voltage Rating - AC: 250 V (exact match required)

Fuse Type: Cartridge, Ceramic (exact match required)

Response Time: Slow Blow (exact match required)

Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required for mechanical compatibility)

Mounting Type: Through Hole (exact match required)

Approval Agency: Must include CE, CSA, and UL certifications (minimum requirement)

RoHS Status: ROHS3 Compliant (required for regulatory compliance)

The substitute part 0325002.HXP from Littelfuse Inc. meets all critical substitution criteria. Additional parameters such as DC voltage rating, operating temperature range, and melting I²t may differ but do not preclude substitution when AC-only operation is specified.

Engineering Selection Recommendations

Primary Selection: BK/MDA-V-2-R (Eaton - Electronics Division)

The BK/MDA-V-2-R is the specified component and should be used when available. It carries active product status with 675 pieces in current inventory.

Approved Substitute: 0325002.HXP (Littelfuse Inc.)

The 0325002.HXP is a qualified substitute for the BK/MDA-V-2-R in applications requiring 2A, 250VAC ceramic cartridge fuses with slow-blow response and through-hole mounting. This substitute meets all mandatory electrical and mechanical parameters. Both parts carry identical core certifications (CE, CSA, UL) and ROHS3 compliance. The Littelfuse part offers additional DC voltage rating (125V) and extended operating temperature range (-55°C ~ 125°C), which provide enhanced capability without compromising AC circuit protection performance. The 0325002.HXP has 1067 pieces in inventory, supporting supply chain continuity.

Selection Criteria:

Use BK/MDA-V-2-R when Eaton-specific sourcing is required or when inventory availability is confirmed.

Use 0325002.HXP when Littelfuse supply is preferred, when extended temperature range is beneficial, or when dual AC/DC voltage capability is advantageous for future application flexibility.

Both parts are suitable for direct substitution in 250VAC, 2A circuit protection applications with identical mechanical fit and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 0325002.HXP replace the BK/MDA-V-2-R in a 250VAC application?

A: Yes. The 0325002.HXP is a direct substitute for AC applications. Both parts have identical current rating (2A), AC voltage rating (250V), fuse type (ceramic cartridge), response time (slow blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), and mounting type (through hole). Both carry CE, CSA, and UL certifications and are ROHS3 compliant.

Q: What is the difference in melting I²t between these parts?

A: The BK/MDA-V-2-R has a melting I²t of 8.8, while the 0325002.HXP has a melting I²t of 80. This difference reflects different thermal characteristics but does not affect substitution eligibility for AC applications at the specified 2A, 250V rating. Both parts meet the same current and voltage protection requirements.

Q: Does the 0325002.HXP DC voltage rating affect AC circuit compatibility?

A: No. The 0325002.HXP includes a 125V DC rating in addition to its 250V AC rating. This additional capability does not impact AC-only applications. The part functions identically to the BK/MDA-V-2-R in 250VAC circuits.

Q: Are the physical dimensions identical between these parts?

A: The dimensions are functionally equivalent for through-hole mounting. BK/MDA-V-2-R: 0.266" Dia x 1.292" L (6.76mm x 32.82mm). 0325002.HXP: 0.275" Dia x 1.288" L (6.99mm x 32.72mm). Both fit the 3AB, 3AG standard package specification and are mechanically compatible with standard fuse holders.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on supplier preference, inventory availability, and any specific requirements for operating temperature range or DC voltage capability. Both parts carry equivalent regulatory approvals and compliance certifications.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. Both parts have identical electrical ratings for AC applications, matching package specifications, and equivalent through-hole mounting compatibility. No circuit modifications or holder changes are required for substitution.
