Littelfuse 0313025.HXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0313025.HXP is a 25A, 32V AC/DC glass cartridge fuse with slow-blow response characteristics, designed for circuit protection in applications requiring a 3AB/3AG form factor. This fuse is actively manufactured and maintains full compliance with RoHS3 and REACH regulations. Alternative equivalent parts may be required due to inventory availability, regional sourcing constraints, or specific packaging preferences while maintaining identical electrical and mechanical specifications.

• Voltage Rating (AC): 32 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Breaking Capacity @ Rated Voltage: 300A (exact match required)
• Melting I²t: 16500 (exact match required)
• DC Cold Resistance: 0.0017 Ohms (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Approval Agency: UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 0313025.MXP meets all specified criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 0313025.HXP and 0313025.MXP are active products manufactured by Littelfuse Inc. with identical electrical, mechanical, and compliance characteristics. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Regional sourcing and supply chain considerations
• Packaging format preferences (both utilize identical 3AB/3AG form factor)
• Compliance requirements (both maintain ROHS3 and REACH compliance)
• UL approval status (both carry identical UL certification)

No technical differentiation exists between these parts. Either part is suitable for direct substitution in applications requiring a 25A, 32V AC/DC slow-blow glass cartridge fuse with 3AB/3AG form factor.

Frequently Asked Questions (FAQ)

Q: Can 0313025.MXP be used as a direct replacement for 0313025.HXP?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications (25A, 32V AC/DC), mechanical dimensions (0.250" Dia x 1.250" L), response characteristics (slow-blow), and compliance certifications (UL, ROHS3, REACH). Direct substitution is permissible without circuit modification.

Q: Are there any compatibility issues with existing 3AB/3AG fuse holders?

A: No. Both parts conform to the identical 3AB/3AG package specification and 1/4" x 1-1/4" form factor. Physical and electrical compatibility with standard 3AB/3AG fuse holders is assured.

Q: What is the difference between the HXP and MXP packaging designations?

A: The HXP and MXP designations represent different packaging or distribution formats from Littelfuse Inc. All electrical and mechanical parameters remain identical. The designation does not affect functional performance or circuit compatibility.

Q: Do both parts meet the same regulatory and approval standards?

A: Yes. Both 0313025.HXP and 0313025.MXP carry identical UL approval, ROHS3 compliance, and REACH unaffected status. No regulatory differentiation exists between the parts.

Q: What is the operating temperature range for these fuses?

A: Both parts operate across the temperature range of -55°C to 125°C, ensuring performance consistency across industrial and commercial applications.
