Key Parameters

Substitute Part Grouping Explanation

The 0874005.MXEP qualifies as a functional equivalent to the 0672005.MXEP based on the following critical parameters:

• Current Rating: Both parts are rated at 5 A
• Voltage Rating (AC): Both parts are rated at 250 V
• Response Time: Both parts feature fast-blow characteristics
• Breaking Capacity: Both parts maintain 50A breaking capacity at rated voltage
• Mounting Type: Both are through-hole axial cartridge configurations
• Approval Certifications: Both meet recognized safety standards (CSA, UL for main part; cULus for substitute)
• RoHS Compliance: Both are ROHS3 compliant

The primary difference is the cartridge material: the 0672005.MXEP uses glass construction, while the 0874005.MXEP uses ceramic construction. Both materials are acceptable for this current and voltage rating class. The 0874005.MXEP is currently active in production, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The 0874005.MXEP is the manufacturer-recommended substitute for the obsolete 0672005.MXEP. Both parts maintain identical electrical specifications for current rating, voltage rating, and response characteristics. The substitute part is currently in active production status, ensuring availability for procurement and inventory management.

The ceramic cartridge construction of the 0874005.MXEP provides equivalent performance to the glass construction of the original part within the specified electrical parameters. Both parts carry recognized safety certifications and maintain ROHS3 compliance. The dimensional differences are minor and fall within the non-standard axial cartridge form factor classification.

Frequently Asked Questions (FAQ)

Q: Can the 0874005.MXEP directly replace the 0672005.MXEP in existing designs?

A: Yes. Both parts share identical current rating (5A), voltage rating (250VAC), response time (fast-blow), and breaking capacity (50A). The electrical performance is equivalent. Physical dimensions differ slightly, but both conform to the non-standard axial cartridge package specification.

Q: What is the difference between glass and ceramic cartridge fuses?

A: Glass and ceramic are both acceptable cartridge materials for this current and voltage class. The 0874005.MXEP ceramic construction provides the same electrical protection characteristics as the glass construction of the 0672005.MXEP.

Q: Are there any compliance or certification differences?

A: The 0672005.MXEP carries CSA and UL approvals. The 0874005.MXEP carries cULus approval. Both certifications are recognized safety standards. Both parts are ROHS3 compliant.

Q: Why is the 0672005.MXEP obsolete?

A: The 0672005.MXEP is classified as obsolete by the manufacturer. The 0874005.MXEP is the active equivalent part in the Littelfuse product line.

Q: Will the 0874005.MXEP fit in the same footprint?

A: The 0874005.MXEP dimensions are 0.142" Dia x 0.394" L (3.60mm x 10.00mm), compared to 0.154" Dia x 0.433" L (3.90mm x 11.00mm) for the original part. Both are classified as non-standard axial cartridge form factors. Physical fit depends on the specific socket or holder design in your application.
