Substitute Part Grouping Explanation

Substitution eligibility for the 0215010.MXF3P is determined by strict equivalence across the following critical parameters:

Parametric Equivalents (Littelfuse Series 215): Parts 0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, and 0215010.MXF56P are parametric equivalents manufactured by Littelfuse Inc. These parts share identical electrical specifications (10 A, 250 V AC, slow-blow response), mechanical dimensions (5.20mm x 20.00mm radial bend cylinder), mounting configuration (through-hole), and thermal operating range (-55°C ~ 125°C). All four parts maintain the same breaking capacity (1.5kA), melting I²t value (334.665), and DC cold resistance (0.0066 Ohms). These parts differ only in internal manufacturing batches or certifications but are functionally interchangeable in circuit applications.

Direct Manufacturer Equivalent (SCHURTER 0001.2514): The SCHURTER SPT 5x20 ceramic fuse (0001.2514) is a direct functional equivalent with matching current rating (10 A), AC voltage rating (250 V), ceramic cartridge construction, slow-blow response, and identical physical dimensions (5.20mm x 20.00mm). This part requires a separate fuse holder for mounting, whereas the Littelfuse radial bend cylinder design integrates mounting leads. The SCHURTER part carries a higher melting I²t value (400 versus 334.665) and includes DC voltage rating (150 V DC) not specified for the primary part. Breaking capacity differs slightly (1kA AC, 1.5kA DC for SCHURTER versus 1.5kA for Littelfuse).

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.MXF3P in all circuit applications requiring 10 A, 250 V AC ceramic fuse protection with radial lead through-hole mounting. All four parts maintain identical electrical performance, thermal ratings, and mechanical compatibility. Selection among these four parts should be based on procurement availability and inventory levels. Parts 0215010.MXF11P (6300 units) and 0215010.MXF56P (2268 units) offer the highest stock availability. Certification coverage is consistent across all four parts, with 0215010.MXF20P and 0215010.MXF34P providing additional BSI and METI approvals, and 0215010.MXF56P including CQC and UR certifications.

SCHURTER 0001.2514 Direct Equivalent: The SCHURTER ceramic fuse is functionally equivalent for AC applications but requires evaluation of mounting configuration. This part requires a separate fuse holder, whereas the Littelfuse radial bend cylinder integrates mounting leads directly into the PCB. The SCHURTER part is suitable only if the circuit design includes a dedicated fuse holder socket. The higher melting I²t value (400 versus 334.665) and explicit DC voltage rating (150 V) indicate slightly different thermal and DC performance characteristics. SCHURTER 0001.2514 offers the highest inventory availability (22984 units) and is certified by cURus and VDE.

Frequently Asked Questions (FAQ)

Q: Can I use 0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, or 0215010.MXF56P interchangeably with 0215010.MXF3P?

A: Yes. All four Littelfuse Series 215 parts are parametric equivalents with identical current rating (10 A), voltage rating (250 V AC), response time (slow-blow), physical dimensions (5.20mm x 20.00mm), and mounting configuration (radial bend cylinder through-hole). They are electrically and mechanically interchangeable in all circuit applications.

Q: What is the difference between the Littelfuse radial bend cylinder and the SCHURTER 5x20 package?

A: The Littelfuse 0215010.MXF3P features integrated radial leads for direct through-hole PCB mounting. The SCHURTER 0001.2514 is a standard 5x20mm cartridge fuse that requires a separate fuse holder socket for mounting. Circuit board design must accommodate the appropriate mounting method.

Q: Can I substitute the SCHURTER 0001.2514 for the Littelfuse 0215010.MXF3P?

A: The SCHURTER 0001.2514 is functionally equivalent for AC fuse protection at 10 A and 250 V. However, it requires a fuse holder for mounting, whereas the Littelfuse part has integrated radial leads. Substitution is possible only if the circuit design includes a compatible fuse holder socket. The SCHURTER part also carries a higher melting I²t value (400 versus 334.665), which may affect nuisance trip characteristics in sensitive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 0215010.MXF3P and all listed substitute parts (0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, 0215010.MXF56P, and 0001.2514) are ROHS3 compliant.

Q: Which substitute part has the best availability?

A: The SCHURTER 0001.2514 has the highest inventory level at 22984 units. Among Littelfuse Series 215 equivalents, the 0215010.MXF11P offers the best availability with 6300 units in stock.

Q: Do all substitute parts carry the same international certifications?

A: The Littelfuse Series 215 parts carry overlapping certifications including CE, CSA, KC, SEMKO, UL, and VDE. Parts 0215010.MXF20P and 0215010.MXF34P include additional BSI and METI approvals. The SCHURTER 0001.2514 is certified by cURus and VDE only, with a narrower certification scope.
