Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0215.800VXP is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 800 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)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Substitute Classification:

Parametric Equivalents (Littelfuse Series 215): Parts 0215.800HXP, 0215.800MXP, and 0215.800TXP are direct parametric equivalents manufactured by Littelfuse Inc. These parts share identical electrical ratings, mechanical dimensions, response characteristics, and approval agency certifications with the main part number.

Direct Manufacturer Equivalent (SCHURTER Inc.): Part 0001.2503 is a ceramic cartridge fuse from SCHURTER Inc. (SPT 5x20 series) that matches all critical electrical and mechanical parameters. This part provides expanded DC voltage rating (300V DC versus unspecified DC for Littelfuse parts) and carries cURus and VDE certifications, making it suitable for applications requiring higher DC voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with international safety standards required for ceramic cartridge fuse applications. Selection between Littelfuse Series 215 equivalents (0215.800HXP, 0215.800MXP, 0215.800TXP) and the main part number 0215.800VXP is based on inventory availability and design documentation requirements, as these parts are parametrically identical with matching certification profiles (CE, CSA, SEMKO, UL, VDE).

The SCHURTER 0001.2503 provides an alternative from a different manufacturer with equivalent AC voltage and current ratings. This part carries cURus and VDE certifications and includes specified 300V DC rating, making it suitable for applications where DC voltage tolerance is a documented requirement. The expanded DC rating does not compromise AC circuit protection performance and maintains the same 1.5kA breaking capacity.

All substitute parts are ROHS3 compliant and operate across the identical temperature range (-55°C ~ 125°C), ensuring compatibility with existing thermal design specifications.

Frequently Asked Questions (FAQ)

Q: Can 0215.800HXP, 0215.800MXP, or 0215.800TXP be used as direct replacements for 0215.800VXP?

A: Yes. These Littelfuse Series 215 parts are parametric equivalents with identical current ratings (800mA), AC voltage ratings (250V), ceramic cartridge construction, slow-blow response time, 5mm x 20mm dimensions, 1.5kA breaking capacity, and approval agency certifications. They are interchangeable for circuit protection applications.

Q: What is the difference between the Littelfuse parts and the SCHURTER 0001.2503?

A: The SCHURTER 0001.2503 is manufactured by a different supplier and carries cURus and VDE certifications rather than the full CE, CSA, SEMKO, UL, VDE certification set of Littelfuse parts. The SCHURTER part specifies 300V DC rating, whereas Littelfuse parts do not specify DC voltage. All parts match on AC voltage (250V), current (800mA), response time (slow-blow), dimensions (5x20mm), and breaking capacity (1.5kA).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts, including 0215.800HXP, 0215.800MXP, 0215.800TXP, and 0001.2503, are ROHS3 compliant and suitable for applications with environmental compliance requirements.

Q: Do these fuses require a holder for installation?

A: Yes. All parts in this substitution group are cartridge fuses that require a fuse holder for installation. The 5mm x 20mm form factor is standard across all parts.

Q: What is the melting I²t specification, and does it affect substitution?

A: The Littelfuse parts specify 0.975 melting I²t, while the SCHURTER 0001.2503 specifies 2.3 melting I²t. This parameter was not identified as a primary matching criterion in the substitution parameters. Both values support the 800mA current rating and 1.5kA breaking capacity across the operating temperature range.

Q: Can I substitute based on approval agency requirements?

A: Substitution should align with your application's certification requirements. If your design requires UL certification, the Littelfuse parts (0215.800HXP, 0215.800MXP, 0215.800TXP) carry UL approval. If your application requires only cURus and VDE certifications, the SCHURTER 0001.2503 is suitable. Verify your specific compliance documentation before final part selection.
