Substitute Part Grouping Explanation

Substitution eligibility for the 0876005.MXEP is determined by strict equivalence across the following critical 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: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Physical Dimensions: 0.142" Dia x 0.394" L / 3.60mm x 10.00mm (exact match required)
• Breaking Capacity @ Rated Voltage: 50A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part 0874005.MXEP meets all critical electrical and mechanical parameters, enabling direct functional replacement in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0876005.MXEP and 0874005.MXEP are Active product status components manufactured by Littelfuse Inc. and comply with ROHS3 requirements. The primary part 0876005.MXEP carries dual approval from cULus and VDE certification bodies, while the substitute 0874005.MXEP holds cULus approval. Both components satisfy identical electrical ratings (5A, 250VAC), mechanical form factors, and thermal operating ranges required for circuit protection applications. Selection between these parts may be based on supply availability, inventory position, or specific certification requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can 0874005.MXEP directly replace 0876005.MXEP in existing designs?

A: Yes. Both parts share identical current rating (5A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (fast blow), mounting configuration (through hole), physical dimensions (0.142" Dia x 0.394" L), and breaking capacity (50A). Direct substitution is electrically and mechanically compatible.

Q: What are the differences between these two part numbers?

A: The parts differ in DC cold resistance (0.0111 Ohms vs. 0.0139 Ohms) and melting I²t values (26.85 vs. 14.58). The main part carries VDE certification in addition to cULus approval, while the substitute carries cULus approval only. These differences do not affect functional equivalence for standard circuit protection applications.

Q: Are both parts suitable for 250VAC applications?

A: Yes. Both the 0876005.MXEP and 0874005.MXEP are rated for 250VAC operation and are approved for AC/DC fuse cartridge applications.

Q: What is the physical form factor of these fuses?

A: Both parts are non-standard axial ceramic cartridge fuses with dimensions of 0.142" diameter by 0.394" length (3.60mm x 10.00mm). They are designed for through-hole mounting on printed circuit boards.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both 0876005.MXEP and 0874005.MXEP are ROHS3 compliant and REACH unaffected, meeting environmental regulatory standards for electronic component manufacturing.
