Littelfuse 0675.200MXEP Ceramic Axial Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0675.200MXEP is a 200 mA, 250 V AC/DC ceramic cartridge fuse with axial through-hole mounting. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The fuse provides slow-blow response characteristics suitable for circuit protection applications requiring ceramic construction and non-standard axial packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0675.200MXEP is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 mA (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)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute: Parts from the same manufacturer (Littelfuse Inc.) with identical electrical and mechanical specifications but different series designations or product status.

Parametric Equivalent: Parts from alternative manufacturers (SCHURTER Inc.) that meet all critical electrical parameters and mechanical dimensions while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

0875.200MXEP (Littelfuse Inc.): This direct manufacturer substitute is the primary replacement option. It maintains active product status, identical electrical specifications, and ROHS3 compliance. The part carries cULus certification and an extended operating temperature range (-55°C to 125°C). Physical dimensions differ slightly (0.142" Dia x 0.394" L versus 0.154" Dia x 0.433" L), and DC cold resistance is lower (0.92 Ohms versus 2.485 Ohms). These dimensional and resistance variations require mechanical fit verification in existing designs.

0675.200MXE (Littelfuse Inc.): This parametric equivalent maintains identical electrical and mechanical specifications to the main part, including the same CSA and UL certifications. However, it carries RoHS non-compliant status, which may restrict use in applications requiring RoHS compliance. Product status is active, supporting continued availability.

8020.0507.PT (SCHURTER Inc.): This parametric equivalent from an alternative manufacturer meets all critical electrical parameters and maintains identical physical dimensions. It carries ROHS3 compliance and CQC/VDE certifications. The breaking capacity is reduced to 35 A (versus 50 A), and the melting I²t value is significantly higher (0.4 versus 0.0158), indicating different thermal response characteristics. Operating temperature range is -20°C to 70°C. This option is suitable only when the reduced breaking capacity and altered thermal response are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 0875.200MXEP be used as a direct replacement for the 0675.200MXEP?

A: The 0875.200MXEP is electrically equivalent with identical current, voltage, and response characteristics. However, physical dimensions differ: the 0875.200MXEP measures 0.142" Dia x 0.394" L compared to 0.154" Dia x 0.433" L for the main part. Mechanical fit verification in the existing PCB or holder is required before substitution.

Q: What is the significance of the different melting I²t values among the substitute parts?

A: Melting I²t defines the thermal energy required to melt the fuse element. The 0875.200MXEP (0.0165) and 0675.200MXE (0.0158) are nearly identical to the main part (0.0158), ensuring comparable thermal response. The 8020.0507.PT (0.4) has substantially higher I²t, resulting in slower thermal response and different protection characteristics.

Q: Are all substitute parts RoHS compliant?

A: The 0875.200MXEP and 8020.0507.PT are ROHS3 compliant. The 0675.200MXE is RoHS non-compliant. RoHS compliance requirements depend on the application's regulatory environment and must be verified before selection.

Q: What certifications apply to each substitute part?

A: The main part carries CSA and UL certifications. The 0875.200MXEP carries cULus certification. The 0675.200MXE carries CSA and UL certifications. The 8020.0507.PT carries CQC and VDE certifications. Certification requirements for the target application must be confirmed before substitution.

Q: Does the reduced breaking capacity of the 8020.0507.PT affect its suitability?

A: The 8020.0507.PT has a breaking capacity of 35 A compared to 50 A for the main part and other substitutes. This reduction may limit its use in applications requiring the higher breaking capacity. System fault current analysis is necessary to determine acceptability.

Q: What is the impact of different DC cold resistance values?

A: DC cold resistance affects voltage drop across the fuse during normal operation. The main part and 0675.200MXE have 2.485 Ohms, while the 0875.200MXEP has 0.92 Ohms. Lower resistance reduces voltage drop and heat generation. Circuit analysis may be required if the application is sensitive to fuse voltage drop.
