Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3402.0011.24 is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.6 A
• Voltage Rating (AC/DC): 63 V / 63 V
• Response Time: Fast Blow
• Mounting Type: Surface Mount
• Package Configuration: 2-SMD, J-Lead
• Breaking Capacity: 50 A
• Melting I²t: 0.27
• Operating Temperature Range: -55°C ~ 125°C
• Physical Dimensions: 0.291" L x 0.122" W x 0.102" H

Parts meeting all these parameters are classified as parametric equivalents and may be used interchangeably in circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 3402.0011.24 and 3402.0011.22 are Active product status components with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and lead time considerations. The 3402.0011.22 variant currently maintains higher inventory levels (2167 Pcs) compared to the 3402.0011.24 (857 Pcs). Both parts carry cURus approval certification and ROHS3 compliance, meeting regulatory requirements for equivalent applications. No design modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the 3402.0011.22 be used as a direct replacement for the 3402.0011.24?

A: Yes. Both parts are parametric equivalents with identical current ratings (1.6 A), voltage ratings (63 V AC/DC), response time (Fast Blow), package configuration (2-SMD J-Lead), and all other critical electrical and mechanical parameters. Direct substitution is possible without circuit modification.

Q: What are the key differences between these two part numbers?

A: There are no functional or electrical differences between 3402.0011.24 and 3402.0011.22. Both are from the SCHURTER OMF 63 series with identical specifications. The part number suffix variation reflects internal SCHURTER product coding but does not indicate design changes.

Q: Are there any compatibility concerns with PCB assembly when switching between these parts?

A: No. Both parts share identical physical dimensions (7.40mm x 3.10mm x 2.60mm) and the same 2-SMD J-Lead package configuration. PCB footprints, pick-and-place programming, and reflow profiles remain unchanged.

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

A: Yes. Both the 3402.0011.24 and 3402.0011.22 carry cURus approval certification, are ROHS3 compliant, and are REACH unaffected. Compliance documentation applies equally to both variants.

Q: What is the melting I²t specification and why is it important for substitution?

A: The melting I²t value of 0.27 defines the thermal energy required to melt the fuse element. Both parts share this identical specification, ensuring equivalent protection characteristics and response behavior in overcurrent conditions.
