Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0215.315MXGP are identified based on strict equivalence across the following critical parameters:

• Current Rating: 315 mA
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Package / Case: 5mm x 20mm
• Response Time: Slow Blow
• Breaking Capacity @ Rated Voltage: 1.5 kA
• Operating Temperature Range: -55°C to 125°C

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications designed for the original part number.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and comply with applicable regulatory requirements. The 0215.315MXP is manufactured by Littelfuse, the same manufacturer as the original part, with identical electrical and mechanical specifications and equivalent certifications. The TCD-315MA from OptiFuse meets all critical electrical parameters and dimensional requirements, with certification to IEC 60127 standard. Selection between these substitutes should be based on availability, supply chain requirements, and certification acceptance criteria specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0215.315MXP be used as a direct replacement for the 0215.315MXGP?

A: Yes. Both parts are manufactured by Littelfuse with identical current rating (315 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (slow blow), breaking capacity (1.5 kA), and operating temperature range (-55°C to 125°C). They are mechanically and electrically interchangeable.

Q: Is the OptiFuse TCD-315MA compatible with fuse holders designed for the 0215.315MXGP?

A: Yes. The TCD-315MA shares identical package dimensions (5mm x 20mm) and mounting type (requires holder). All critical electrical parameters match: 315 mA current rating, 250 V AC voltage rating, ceramic cartridge construction, slow-blow response, and 1.5 kA breaking capacity. Physical compatibility with standard 5mm x 20mm fuse holders is confirmed.

Q: What are the key parameters that determine substitutability for this fuse?

A: Substitutability is determined by equivalence in current rating (315 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (slow blow), breaking capacity (1.5 kA), and operating temperature range (-55°C to 125°C). All substitute parts listed meet these criteria.

Q: Are there differences in certifications between the substitute parts?

A: The 0215.315MXP carries CE, SEMKO, UL, and VDE certifications. The TCD-315MA is certified to IEC 60127. Both are ROHS3 compliant. Certification acceptance should be verified against application-specific requirements.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All listed parts are rated for 250 V AC/DC operation, as specified in their detailed descriptions.
