Frequently Asked Questions (FAQ)

Q: Can 3402.0004.22 be used as a direct replacement for 3402.0004.24?

A: Yes. Both parts are parametric equivalents with identical current ratings (100 mA), voltage ratings (63 V AC/DC), response characteristics (Fast Blow), package configuration (2-SMD, J-Lead), and physical dimensions. They share the same base product number and series designation.

Q: Are there any differences in the package or mounting requirements?

A: No. Both parts use identical 2-SMD, J-Lead surface mount packages with the same physical dimensions (7.40mm x 3.10mm x 2.60mm). They are supplied in Tape & Reel (TR) packaging and require no modification to existing PCB layouts or assembly processes.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the 3402.0004.24 and 3402.0004.22 carry cURus approval certification and maintain ROHS3 compliance. They are classified as REACH Unaffected and carry the same ECCN (EAR99) and HTSUS (8536.10.0040) designations.

Q: What is the difference between these two part numbers if they are identical?

A: The parts are functionally and electrically identical. The different part numbers (3402.0004.24 and 3402.0004.22) represent different manufacturing batches or inventory tracking designations within SCHURTER's product line, both derived from the same base product number (3402.0004).

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

A: Yes. Both parts are rated for 63 V AC and 63 V DC operation, making them suitable for dual-voltage applications. The fast-blow response time applies to both AC and DC circuit protection scenarios.

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

A: Both parts operate across the temperature range of -55°C to 125°C, ensuring performance stability in industrial and commercial applications across standard environmental conditions.
