Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3402.0007.24 is determined by strict equivalence across the following critical parameters:

Current Rating: 400 mA (exact match required) Voltage Rating: 63 V AC and 63 V DC (both must match) Response Time: Fast Blow (characteristic must be identical) Mounting Type: Surface Mount (package form factor must be compatible) Package / Case: 2-SMD, J-Lead (physical and electrical interface must be identical) Breaking Capacity: 50 A @ Rated Voltage (fault protection capability must match) Melting I²t: 0.016 (thermal energy threshold must be identical) Operating Temperature Range: -55°C to 125°C (thermal performance envelope must match) Series: OMF 63 (product line consistency)

Only parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3402.0007.22 is a direct parametric equivalent to the 3402.0007.24. Both parts are manufactured by SCHURTER Inc., belong to the OMF 63 series, and share identical electrical ratings, thermal characteristics, and mechanical specifications. Both parts maintain active product status and carry cURus approval certification with ROHS3 compliance.

Selection between these two part numbers may be based on inventory availability, supply chain logistics, or manufacturing batch considerations. The 3402.0007.22 currently has higher inventory availability (3965 pcs) compared to the 3402.0007.24 (1020 pcs). Both parts are supplied in Tape & Reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 3402.0007.22 be used as a direct replacement for the 3402.0007.24 in existing designs?

A: Yes. Both parts are parametric equivalents with identical current ratings (400 mA), voltage ratings (63 V AC/DC), response characteristics (Fast Blow), package form (2-SMD, J-Lead), and thermal specifications. No circuit redesign or re-qualification is required.

Q: Are there any differences in the physical footprint between these two parts?

A: No. Both parts have identical dimensions of 7.40 mm length × 3.10 mm width × 2.60 mm height and use the same 2-SMD, J-Lead package configuration. PCB layout and assembly tooling remain unchanged.

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

A: Yes. Both the 3402.0007.24 and 3402.0007.22 are ROHS3 compliant, carry cURus approval certification, and are REACH unaffected. Compliance documentation applies equally to both part numbers.

Q: What is the difference between the part numbers if all specifications are identical?

A: The part numbers differ in their suffix designation (.24 versus .22), which typically indicates different manufacturing batches, tape reel configurations, or internal SCHURTER product line variants. The electrical and mechanical specifications remain identical.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical specifications, they may be used interchangeably within the same assembly or production run without affecting circuit performance or reliability.
