Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.0521.PT directly replace the Littelfuse 0675005.MXE in existing designs?

A: Yes. Both components share identical current rating (5A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (slow blow), mounting type (through hole), and physical dimensions (0.154" Dia x 0.433" L). Direct substitution is supported at the circuit level.

Q: What are the differences in breaking capacity between these two fuses?

A: The Littelfuse 0675005.MXE has a breaking capacity of 50A at rated voltage, while the SCHURTER 8020.0521.PT has a breaking capacity of 40A at rated voltage. Both values exceed the 5A current rating and are suitable for standard circuit protection applications.

Q: Does the SCHURTER component meet RoHS requirements?

A: Yes. The SCHURTER 8020.0521.PT is ROHS3 compliant. The Littelfuse 0675005.MXE is RoHS non-compliant. Applications requiring RoHS compliance should specify the SCHURTER component.

Q: Are the certifications equivalent between these two fuses?

A: The certifications differ. The Littelfuse component carries CSA and UL approvals. The SCHURTER component carries CQC, cURus, and VDE approvals. Selection should align with regional and application-specific certification requirements.

Q: What is the difference in melting I²t values?

A: The Littelfuse 0675005.MXE has a melting I²t of 58.8, while the SCHURTER 8020.0521.PT has a melting I²t of 250. Both components are rated for 5A slow-blow operation and are suitable for their intended applications.
