Littelfuse 0325005.HXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0325005.HXP is a 5A 250VAC ceramic cartridge fuse designed for through-hole mounting in 3AB/3AG package format (1/4" x 1-1/4" axial). This slow-blow fuse is classified as Active product status and is widely used in industrial and commercial electrical protection circuits. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in existing designs and assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0325005.HXP is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 5 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)
• Approval Certifications: Minimum CE, CSA, UL compliance required

The Eaton Electronics Division part number BK/MDA-V-5-R meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0325005.HXP and Eaton BK/MDA-V-5-R maintain Active product status and satisfy core regulatory compliance requirements (CE, CSA, UL). The Littelfuse part provides higher breaking capacity (400A versus 200A) and lower melting I²t (25 versus 65), while the Eaton part offers lower DC cold resistance (0.023 Ohms versus 0.0522 Ohms). Dimensional tolerances between the two parts are minimal and fall within standard 3AB/3AG package specifications. Selection between these parts should be based on specific circuit protection requirements and breaking capacity demands of the application.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/MDA-V-5-R be used as a direct replacement for the Littelfuse 0325005.HXP?

A: Yes. Both parts share identical electrical ratings (5A, 250VAC), fuse type (ceramic cartridge), response time (slow blow), and package format (3AB/3AG, 1/4" x 1-1/4" axial). Dimensional differences are within standard package tolerances. Both parts carry Active product status and required regulatory certifications.

Q: What are the key differences between these two fuses?

A: The primary differences are breaking capacity (Littelfuse 400A versus Eaton 200A), melting I²t (Littelfuse 25 versus Eaton 65), and DC cold resistance (Littelfuse 0.0522 Ohms versus Eaton 0.023 Ohms). These differences do not affect substitution eligibility for standard 5A 250VAC applications but may influence performance in high-fault-current environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the Littelfuse 0325005.HXP and Eaton BK/MDA-V-5-R are ROHS3 compliant.

Q: What certifications do these fuses carry?

A: The Littelfuse part carries CE, CSA, PSE, and UL certifications. The Eaton part carries CE, CSA, and UL certifications. Both meet minimum required approval standards for industrial and commercial applications.

Q: Are there dimensional compatibility concerns when substituting between these parts?

A: Dimensional differences are minimal (Littelfuse 0.275" Dia x 1.288" L versus Eaton 0.266" Dia x 1.292" L) and fall within standard 3AB/3AG package specifications. Both parts are designed for identical through-hole mounting configurations and will fit standard fuse holders without modification.
