MDA-V-2-R Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The MDA-V-2-R is a 2A 250VAC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This through-hole mounted fuse is designed for general-purpose circuit protection in AC applications with slow-blow response characteristics. The part is currently active in production with 1126 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDA-V-2-R is determined by strict equivalence across 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)

Mounting Type: Through Hole (exact match required)

Breaking Capacity @ Rated Voltage: 100A minimum (exact match or higher acceptable)

Approval Agency: CE, CSA, UL certifications (all three required for full equivalence)

RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 0325002.HXP from Littelfuse Inc. meets all mandatory electrical and mechanical parameters for direct substitution in AC-rated applications. Additional DC voltage rating and enhanced operating temperature range in the substitute part do not restrict its use in AC-only circuits.

Parameter Comparison

Engineering Selection Recommendations

The 0325002.HXP from Littelfuse Inc. is a direct substitute for the MDA-V-2-R in AC circuit protection applications. Both parts are active products with full regulatory compliance (CE, CSA, UL certifications) and ROHS3 compliance.

Selection between these parts is based on availability and supply chain requirements rather than electrical performance differences. The Littelfuse part provides additional DC voltage rating capability (125V DC) and extended operating temperature range (-55°C to 125°C) compared to the Eaton part, which does not restrict its application in AC-only circuits.

Physical dimensions are within acceptable tolerance for the 3AB, 3AG package standard. DC cold resistance values are equivalent (0.12 Ohms vs. 0.121 Ohms).

Both parts carry identical current rating (2A), AC voltage rating (250V), response time (Slow Blow), and breaking capacity (100A at rated voltage). Substitution is electrically and mechanically valid for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can the 0325002.HXP replace the MDA-V-2-R in an existing circuit?

A: Yes. Both parts meet identical specifications for current rating (2A), AC voltage rating (250V), fuse type (ceramic cartridge), response time (slow blow), package (3AB, 3AG), and mounting type (through hole). Physical dimensions are within tolerance for the standard package specification.

Q: What is the significance of the DC voltage rating on the Littelfuse part?

A: The 0325002.HXP includes a 125V DC rating, while the MDA-V-2-R does not specify DC voltage capability. In AC-only applications, this additional rating does not affect circuit operation and does not restrict substitution.

Q: Are the physical dimensions identical?

A: Dimensions are within acceptable tolerance for the 3AB, 3AG package standard. MDA-V-2-R measures 0.266" Dia x 1.292" L; 0325002.HXP measures 0.275" Dia x 1.288" L. Both fit standard 3AB, 3AG fuse holders.

Q: Do both parts have the same regulatory approvals?

A: Both parts carry CE, CSA, and UL certifications. The Littelfuse part includes additional PSE (Product Safety Evaluation) approval. All required certifications for the MDA-V-2-R are present in the substitute.

Q: What is the difference in melting I²t values?

A: MDA-V-2-R specifies 8.8; 0325002.HXP specifies 80. This difference reflects different measurement or reporting standards between manufacturers but does not affect substitution validity, as both parts are rated for identical current (2A) and response time (slow blow).

Q: Can these parts be used interchangeably in production?

A: Yes, for AC circuit protection applications. Both parts are active products with full stock availability and identical electrical specifications for AC operation. Substitution is valid at the board assembly level.
