Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0677002.MXE is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (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)
• Physical Dimensions: 0.154" Dia x 0.433" L / 3.90mm x 11.00mm (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)

The SCHURTER Inc. part 8020.0517.PT meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0677002.MXE and SCHURTER 8020.0517.PT maintain active product status with full regulatory compliance. The Littelfuse part carries CSA, UL, and VDE approvals, while the SCHURTER substitute carries CQC, cURus, and VDE approvals. Both parts are ROHS3 compliant and REACH unaffected. Selection between these parts should be based on supply availability, approval agency requirements specific to the end application, and inventory status. The SCHURTER part currently maintains higher inventory (3277 units) compared to the Littelfuse part (1038 units).

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.0517.PT be used as a direct replacement for the Littelfuse 0677002.MXE?

A: Yes. Both parts are parametric equivalents with identical current rating (2A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (slow blow), mounting type (through hole), and physical dimensions (0.154" Dia x 0.433" L). Both maintain active product status and equivalent regulatory compliance.

Q: What is the difference in Melting I²t between these parts?

A: The Littelfuse part specifies 20.8 while the SCHURTER part specifies 32. This parameter was provided in the source data and is documented for reference. Both parts meet the 35A breaking capacity requirement at rated voltage.

Q: Are there operating temperature differences between these parts?

A: The Littelfuse part does not specify an operating temperature range. The SCHURTER part specifies -20°C ~ 70°C. Both parts are suitable for standard industrial and commercial applications within normal operating conditions.

Q: Which regulatory approvals should I consider for my application?

A: The Littelfuse part carries CSA, UL, and VDE approvals. The SCHURTER part carries CQC, cURus, and VDE approvals. Select the part whose approval agencies align with your application's geographic and regulatory requirements.

Q: Is there a difference in moisture sensitivity between these parts?

A: The Littelfuse part specifies MSL 1 (Unlimited). The SCHURTER part specifies MSL as Not Applicable. Both parts are suitable for standard handling and storage conditions.
