Frequently Asked Questions (FAQ)

Q: Can the 3404.2321.22 be used as a direct replacement for the 3404.2321.23?

A: Yes. The 3404.2321.22 is a parametric equivalent with identical electrical ratings (375 mA, 125 V AC/DC), response time (Slow Blow), mounting configuration (Requires Holder, Surface Mount), package type (2-SMD, Square End Block with Holder), and physical dimensions (12.00mm x 5.20mm x 6.00mm). No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance status and REACH Unaffected designation. Both are classified as active products from SCHURTER Inc.

Q: What is the significance of the breaking capacity rating?

A: The breaking capacity of 100 A at rated voltage indicates the maximum fault current the fuse can safely interrupt without damage to the fuse holder or circuit board. This specification is identical for both parts.

Q: Does the melting I²t value affect substitution eligibility?

A: Yes. The melting I²t value of 0.054 is a critical thermal characteristic that determines the fuse's response to overcurrent conditions. Both parts have identical values, confirming thermal equivalence.

Q: Are these fuses suitable for both AC and DC applications?

A: Yes. Both parts are rated for 125 V AC and 125 V DC operation, making them suitable for dual-voltage applications within the specified voltage range.

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

A: Both parts operate across the range of -40°C to 85°C, suitable for industrial and commercial environments with standard temperature variations.
