Substitute Part Grouping Explanation

Substitute parts for the 0215010.MXF4P are classified into two categories based on substitution criteria:

Parametric Equivalents (Littelfuse Series 215): Parts 0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, and 0215010.MXF56P are direct parametric equivalents manufactured by Littelfuse. These parts share identical electrical specifications (10A, 250VAC, slow-blow ceramic cartridge), mechanical form factor (radial bend cylinder, 5.20mm x 20.00mm), mounting method (through-hole), and operating temperature range (-55°C to 125°C). The primary distinction among these parts lies in their approval agency certifications, which may vary by regional market requirement. All maintain the same 1.5kA breaking capacity and 0.0066 Ohms DC cold resistance.

Direct Manufacturer Equivalent (SCHURTER 0001.2514): Part 0001.2514 from SCHURTER Inc. is a direct functional equivalent with identical current rating (10A), AC voltage rating (250V), ceramic cartridge construction, slow-blow response, and physical dimensions (5.20mm x 20.00mm). This part differs in that it requires a separate fuse holder for mounting (versus radial bend leads) and includes a DC voltage rating specification (150V DC). The breaking capacity is specified as 1kA AC and 1.5kA DC, with a slightly higher melting I²t value of 400 compared to 334.665 for the Littelfuse series.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse Series 215 Parametric Equivalents (0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, 0215010.MXF56P): These parts are direct substitutes for the 0215010.MXF4P in applications requiring identical electrical and mechanical specifications. Selection among these four variants should be based on regional certification requirements. The 0215010.MXF20P includes BSI and METI certifications in addition to the standard set, while 0215010.MXF34P and 0215010.MXF56P include BSI and METI certifications. The 0215010.MXF56P adds CQC and UR certifications. Choose the variant that aligns with your target market's regulatory requirements. All four maintain active product status and are in stock.

SCHURTER 0001.2514: This part is suitable as a substitute when the application permits use of a fuse holder assembly rather than radial bend leads. The SCHURTER part is appropriate for designs where the fuse is mounted in a dedicated holder socket. This part offers significantly higher inventory availability (22,984 units) and includes explicit DC voltage rating (150V DC). The slightly elevated melting I²t value (400 versus 334.665) indicates marginally slower thermal response. Use this substitute only when the circuit board layout and mechanical design accommodate holder-based mounting.

Frequently Asked Questions (FAQ)

Q: Can I use 0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, or 0215010.MXF56P as direct replacements for 0215010.MXF4P?

A: Yes. All four Littelfuse Series 215 parts are parametric equivalents with identical electrical ratings (10A, 250VAC), response time (slow-blow), ceramic construction, and physical dimensions (5.20mm x 20.00mm radial bend cylinder). They differ only in regional approval certifications. Select the variant matching your market's regulatory requirements.

Q: What is the difference between the Littelfuse radial bend variants and the SCHURTER 0001.2514?

A: The Littelfuse parts feature radial bend leads for direct through-hole PCB mounting. The SCHURTER 0001.2514 is a cartridge fuse requiring a separate fuse holder for mounting. Both share identical current and AC voltage ratings. The SCHURTER part includes DC voltage rating specification (150V DC) and higher inventory availability.

Q: Can I substitute the SCHURTER 0001.2514 for the Littelfuse 0215010.MXF4P without circuit board redesign?

A: No. The SCHURTER part requires a fuse holder assembly, whereas the Littelfuse part uses radial bend leads for direct PCB mounting. Circuit board layout and component footprint must be modified to accommodate holder-based mounting.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the Littelfuse Series 215 variants and SCHURTER 0001.2514, are ROHS3 compliant.

Q: Which substitute part has the best availability?

A: The SCHURTER 0001.2514 has the highest inventory with 22,984 units in stock. Among Littelfuse variants, the 0215010.MXF11P offers the highest availability with 6,300 units.

Q: Do the Littelfuse Series 215 variants have different breaking capacities?

A: No. All Littelfuse Series 215 variants (0215010.MXF4P, 0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, and 0215010.MXF56P) maintain identical breaking capacity of 1.5kA at rated voltage and melting I²t of 334.665.
