Substitute Part Grouping Explanation

Substitute parts for the 0285.315HXP are qualified based on strict equivalence of the following electrical and mechanical parameters:

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

Two substitute parts meet these criteria: the 0215.315MXP from Littelfuse Inc. and the TCD-315MA from OptiFuse. Both maintain identical electrical performance specifications and physical dimensions, ensuring direct functional replacement in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical equivalence to the 0285.315HXP. The 0215.315MXP, also from Littelfuse Inc., carries additional approval certifications including CE, SEMKO, UL, and VDE, providing expanded regulatory coverage. The TCD-315MA from OptiFuse meets IEC 60127 standards and maintains equivalent performance specifications. Selection between these substitutes should be based on supply availability, regulatory requirements specific to the application, and existing component qualification within the design.

Frequently Asked Questions (FAQ)

Q: Can the 0215.315MXP be used as a direct replacement for the 0285.315HXP?

A: Yes. Both parts are 315 mA, 250 V AC/DC ceramic cartridge fuses in 5mm x 20mm packages with slow-blow response and 1.5 kA breaking capacity. They are electrically and mechanically equivalent.

Q: What is the difference between the 0285.315HXP and 0215.315MXP?

A: The primary differences are the series designation (285 versus 215) and approval certifications. The 0215.315MXP includes CE, SEMKO, UL, and VDE approvals, while the 0285.315HXP does not list specific approval agencies. All electrical and mechanical parameters are identical.

Q: Is the TCD-315MA from OptiFuse compatible with the 0285.315HXP?

A: Yes. The TCD-315MA meets all electrical and mechanical requirements: 315 mA current rating, 250 V AC/DC voltage rating, ceramic cartridge construction, 5mm x 20mm package, slow-blow response, and 1.5 kA breaking capacity. It is certified to IEC 60127 standards.

Q: Do these fuses require a specific holder?

A: All three parts require a fuse holder rated for 5mm x 20mm cartridge fuses. The holder must be compatible with the circuit voltage and current specifications of the application.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 0285.315HXP, 0215.315MXP, and TCD-315MA are all ROHS3 compliant.

Q: What is the operating temperature range for these fuses?

A: All three parts operate across the temperature range of -55°C to 125°C.
