MDA-V-1-R Equivalent & Substitute Parts

Part Overview

The MDA-V-1-R is a 1 A, 250 V AC 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 700 pieces in stock.

Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-V-1-R are identified based on strict electrical and mechanical parameter alignment:

Electrical Parameters:

• Current rating must equal 1 A
• AC voltage rating must be 250 V minimum
• Response time classification must be Slow Blow
• Fuse type must be Cartridge, Ceramic

Mechanical Parameters:

• Package designation must be 3AB, 3AG
• Physical dimensions must be 1/4" x 1-1/4" (Axial) to ensure compatibility with existing fuse holders
• Mounting type must be Through Hole

Compliance Parameters:

• Substitute parts must maintain CE, CSA, and UL certifications as minimum regulatory requirements
• RoHS3 compliance is required

The substitute part 0325001.HXP from Littelfuse Inc. meets all critical substitution criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MDA-V-1-R (Eaton - Electronics Division)

The MDA-V-1-R remains the specified component when supply is available. It carries active product status with 700 pieces in current inventory and meets all required certifications (CE, CSA, UL) and RoHS3 compliance.

Equivalent Substitute: 0325001.HXP (Littelfuse Inc.)

The 0325001.HXP is a direct electrical and mechanical equivalent suitable for substitution when MDA-V-1-R availability is constrained. This part maintains:

• Identical current rating (1 A) and AC voltage rating (250 V)
• Identical fuse type (Cartridge, Ceramic) and response time (Slow Blow)
• Compatible package designation (3AB, 3AG) and through-hole mounting
• Equivalent DC cold resistance (0.389 Ohms vs. 0.38 Ohms)
• Active product status with 896 pieces in inventory
• Full regulatory compliance (CE, CSA, PSE, UL) and RoHS3 certification

The 0325001.HXP provides enhanced breaking capacity (100 A AC vs. 35 A) and includes DC voltage rating (125 V), which represents a superset of the original specification and does not create incompatibility in AC-only applications.

Physical dimensions are within standard tolerance for the 3AB, 3AG package class, ensuring compatibility with existing fuse holders and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can 0325001.HXP be used as a direct replacement for MDA-V-1-R in all applications?

A: Yes. The 0325001.HXP meets all critical electrical parameters (1 A, 250 V AC, Slow Blow, Ceramic Cartridge) and mechanical parameters (3AB, 3AG, 1/4" x 1-1/4" through-hole). Physical dimensions are within standard tolerance for this package class. Both parts carry equivalent regulatory certifications and RoHS3 compliance.

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

A: The 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. In AC-only circuits operating at 250 V, the higher breaking capacity of the substitute does not create incompatibility and provides additional safety margin.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent within standard tolerance for the 3AB, 3AG package designation. MDA-V-1-R measures 0.266" Dia x 1.292" L; 0325001.HXP measures 0.275" Dia x 1.288" L. Both conform to the 1/4" x 1-1/4" (Axial) specification and are compatible with standard fuse holders for this package class.

Q: Does the 0325001.HXP DC voltage rating affect AC-only applications?

A: No. The 0325001.HXP includes a 125 V DC rating in addition to the 250 V AC rating. In AC-only circuits, this additional rating does not impact performance or compatibility. The part is suitable for direct substitution in AC applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MDA-V-1-R and 0325001.HXP are RoHS3 compliant and meet current environmental regulations.

Q: What regulatory certifications apply to both parts?

A: Both parts carry CE, CSA, and UL certifications. The 0325001.HXP additionally carries PSE certification, which does not affect compatibility in markets requiring CE, CSA, or UL compliance.
