Equivalent & Substitute Parts for MDA-V-10-R

Part Overview

The MDA-V-10-R is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 10 A at 250 V AC/DC with slow-blow response characteristics. This through-hole component is housed in a 3AB, 3AG package format (1/4" x 1-1/4" axial) and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in circuit protection applications where the original part number may be unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDA-V-10-R is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Current Rating: 10 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)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Identified Substitute Parts:

1. BK/MDA-V-10-R (Eaton - Electronics Division) – Direct manufacturer variant with identical electrical and mechanical specifications
2. 0325010.HXP (Littelfuse Inc.) – Cross-manufacturer equivalent meeting all primary criteria
3. 0325010.MXP (Littelfuse Inc.) – Cross-manufacturer equivalent meeting all primary criteria

All three substitute parts satisfy the mandatory parameter alignment required for direct replacement in the MDA-V-10-R application.

Parameter Comparison

Engineering Selection Recommendations

BK/MDA-V-10-R Selection: This part is a direct manufacturer variant from Eaton - Electronics Division with identical electrical specifications and certifications (CE, CSA, UL). It provides the most direct substitution path with matching breaking capacity (200 A) and melting I²t (332). Selection is appropriate when maintaining consistency with the original Eaton product line is required.

0325010.HXP and 0325010.MXP Selection: Both Littelfuse parts meet all mandatory substitution criteria and provide enhanced breaking capacity (400 A versus 200 A) and broader temperature operating range (-55°C ~ 125°C). These parts carry expanded approval certifications including K-MARK and PSE. Selection is appropriate when higher breaking capacity or extended temperature performance is beneficial to the application. The Littelfuse parts feature lower melting I²t (137 versus 332), indicating faster thermal response characteristics within the slow-blow classification.

All substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory alignment and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can 0325010.HXP and 0325010.MXP be used interchangeably with MDA-V-10-R?

A: Yes. Both Littelfuse parts satisfy all mandatory electrical and mechanical parameters: 10 A current rating, 250 V AC voltage rating, ceramic cartridge type, slow-blow response, and 3AB/3AG package format. All three parts are Active status with ROHS3 compliance.

Q: What is the difference between the Littelfuse parts (0325010.HXP and 0325010.MXP) and the Eaton parts?

A: The Littelfuse parts feature higher breaking capacity (400 A versus 200 A), lower melting I²t (137 versus 332), specified operating temperature range (-55°C ~ 125°C), and additional approval certifications (K-MARK, PSE). The Eaton parts maintain identical current, voltage, and package specifications.

Q: Are there any physical dimension differences between substitute parts?

A: Minor dimensional variations exist. MDA-V-10-R and BK/MDA-V-10-R are 0.266" diameter x 1.292" length. Littelfuse parts (0325010.HXP and 0325010.MXP) are 0.275" diameter x 1.288" length. Both dimensions conform to 3AB, 3AG package specifications and are compatible with standard through-hole fuse holders.

Q: Which substitute part should be selected for applications requiring extended temperature operation?

A: The Littelfuse parts (0325010.HXP and 0325010.MXP) specify operating temperature range of -55°C ~ 125°C. The Eaton parts do not specify operating temperature limits. Selection depends on application temperature requirements.

Q: Do all substitute parts carry the same regulatory approvals?

A: MDA-V-10-R and BK/MDA-V-10-R carry CE, CSA, and UL approvals. Littelfuse parts (0325010.HXP and 0325010.MXP) carry CE, CSA, K-MARK, PSE, and UL approvals, providing broader international certification coverage.

Q: What is the significance of the different melting I²t values?

A: Melting I²t indicates thermal response speed. MDA-V-10-R and BK/MDA-V-10-R have I²t of 332, while Littelfuse parts have I²t of 137. Both are classified as slow-blow fuses. The lower I²t in Littelfuse parts indicates faster thermal response within the slow-blow category.
