Substitute Part Grouping Explanation

Substitution eligibility for the 0215.630VXP is determined by the following critical parameters:

• Current Rating: 630 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute parts are grouped into two categories:

Parametric Equivalents (Littelfuse Series 215): Parts 0215.630HXP and 0215.630TXP match all critical electrical and mechanical parameters with identical specifications across current rating, voltage, breaking capacity, melting I²t, and thermal characteristics.

Direct Manufacturer Substitute (SCHURTER Inc.): Part 0001.2502 matches all critical parameters with the exception of DC voltage rating (300V DC vs. unspecified for main part) and breaking capacity specification availability. This part is suitable for applications where AC 250V operation is the primary requirement.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 0215.630HXP and 0215.630TXP: These parts are direct parametric equivalents to the 0215.630VXP. All electrical characteristics, mechanical dimensions, thermal performance, and regulatory certifications are identical. Selection between these three Littelfuse parts may be based on inventory availability and lead time requirements. All three parts carry full UL, CSA, SEMKO, CE, and VDE approvals.

SCHURTER 0001.2502: This part is suitable as a substitute where AC 250V operation is the primary circuit requirement. The part meets all critical mechanical and electrical parameters for 630mA, 250VAC operation in a 5x20mm ceramic cartridge form factor. The SCHURTER part carries cURus and VDE approvals. The absence of specified breaking capacity and melting I²t values in the provided data should be cross-referenced with the manufacturer's technical documentation for applications requiring these specific performance metrics. The higher DC voltage rating (300V) provides additional margin in mixed AC/DC applications.

Frequently Asked Questions (FAQ)

Q: Can 0215.630HXP and 0215.630TXP be used interchangeably with 0215.630VXP?

A: Yes. These Littelfuse parts are parametric equivalents with identical current ratings (630mA), voltage ratings (250VAC), package dimensions (5x20mm), response characteristics (slow blow), breaking capacity (1.5kA), and thermal specifications. All three parts carry the same regulatory certifications.

Q: Is the SCHURTER 0001.2502 a direct replacement for the Littelfuse 0215.630VXP?

A: The SCHURTER 0001.2502 is functionally compatible for 630mA, 250VAC applications in the 5x20mm ceramic cartridge format. It meets the critical electrical and mechanical parameters. However, the SCHURTER part has a different approval agency set (cURus, VDE vs. CE, CSA, SEMKO, UL, VDE). Verify that the SCHURTER certifications satisfy your application's regulatory requirements before substitution.

Q: What is the significance of the 5x20mm package dimension?

A: The 5x20mm dimension specifies the physical form factor of the ceramic cartridge fuse. This dimension determines compatibility with standard fuse holders designed for this size. All substitute parts listed maintain this exact dimension, ensuring mechanical interchangeability in existing fuse holder installations.

Q: Why is the response time specification important for substitution?

A: Response time (slow blow vs. fast blow) determines how quickly the fuse element melts under overcurrent conditions. All parts listed are slow-blow fuses, meaning they tolerate brief inrush currents before opening. Substituting with a fast-blow fuse would cause nuisance trips in circuits with normal inrush current characteristics.

Q: What does the melting I²t value indicate?

A: The melting I²t (0.635) is a thermal energy parameter that characterizes the fuse's response to overcurrent. This value must match between the main part and substitute to ensure identical protection characteristics. The Littelfuse equivalents (0215.630HXP and 0215.630TXP) match this specification exactly.

Q: Are all listed parts RoHS3 compliant?

A: Yes. All four parts (0215.630VXP, 0215.630HXP, 0215.630TXP, and 0001.2502) are ROHS3 compliant and suitable for applications with RoHS requirements.
