Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0876002.MXESZP are qualified based on the following critical parameters that determine functional interchangeability:

• Current Rating: 2 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)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Size / Dimension: 0.142" Dia x 0.394" L (3.60mm x 10.00mm) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The identified substitutes meet all critical electrical and mechanical parameters. Variations in secondary characteristics such as breaking capacity, melting I²t, DC cold resistance, and approval agency certifications do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products manufactured by Littelfuse Inc. and comply with ROHS3 requirements. Selection between the main part and substitutes should be based on:

• Availability: 0874002.MXEP offers the highest inventory level at 2047 units
• Certification Requirements: 0876002.MXESZP includes cURus, CQC, KC, PSE, VDE, and CQC approvals; 0876002.MXEP includes cULus and VDE; 0874002.MXEP includes cULus only. Verify certification alignment with application requirements
• Secondary Performance Characteristics: 0874002.MXEP provides higher breaking capacity (50A vs 35A) and lower melting I²t (1.812 vs 2.51), which may be advantageous in high-fault-current environments

Frequently Asked Questions (FAQ)

Q: Can 0876002.MXEP and 0874002.MXEP be used interchangeably with 0876002.MXESZP?

A: Yes, both substitutes meet all critical electrical and mechanical parameters: 2A current rating, 250V AC voltage rating, ceramic cartridge construction, fast-blow response, axial package, through-hole mounting, and identical physical dimensions. They are functionally compatible for standard circuit protection applications.

Q: What is the difference between the three parts?

A: The main differences are in secondary performance characteristics and certifications. 0876002.MXESZP and 0876002.MXEP share identical breaking capacity (35A) and melting I²t (2.51), while 0874002.MXEP has higher breaking capacity (50A) and lower melting I²t (1.812). Certification coverage varies across the three parts.

Q: Does the difference in breaking capacity affect compatibility?

A: Breaking capacity is a secondary parameter that does not affect functional interchangeability in standard applications. The higher breaking capacity of 0874002.MXEP (50A vs 35A) provides additional margin in high-fault-current environments but does not prevent substitution in circuits designed for the 35A rating.

Q: Are there any packaging or mounting differences?

A: No. All three parts use identical through-hole axial cartridge packaging with dimensions of 0.142" Dia x 0.394" L (3.60mm x 10.00mm). They mount identically on PCBs and are mechanically interchangeable.

Q: Which part should I select for new designs?

A: Selection depends on certification requirements, availability, and application-specific fault-current conditions. Verify that the chosen part's certifications (cULus, VDE, CQC, KC, PSE) align with your product's regulatory requirements.
