Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.6040 are identified based on strict parametric equivalence across the following critical specifications:

Current Rating: 400 mA (exact match required) Voltage Rating: 250 V AC (exact match required) Response Time: Fast Blow (exact match required) Package / Case: Radial, Can, Vertical (exact match required) Mounting Type: Through Hole (exact match required) Size / Dimension: 0.335" Dia x 0.335" H / 8.50mm x 8.50mm (exact match required) Breaking Capacity: 35A (exact match required) Melting I²t: 0.044 (exact match required) Approval Agencies: CCC, cURus, VDE (exact match required) Operating Temperature Range: -40°C ~ 85°C (exact match required)

Only parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0034.6010 is a direct parametric equivalent to the 0034.6040. Both parts are manufactured by SCHURTER Inc., belong to the MSF 250 series, and carry identical electrical, mechanical, and regulatory specifications. Both components maintain active product status and hold equivalent international certifications (CCC, cURus, VDE). Both are ROHS3 compliant and REACH unaffected, meeting current environmental and safety requirements. Selection between these parts may be based on inventory availability, lead time, or procurement preference, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the 0034.6010 be used as a direct replacement for the 0034.6040?

A: Yes. The 0034.6010 is a parametric equivalent with identical electrical ratings (400 mA, 250 V AC), response time (fast blow), mechanical dimensions (0.335" Dia x 0.335" H), mounting type (through hole), and regulatory certifications. Direct substitution is permissible without circuit modification.

Q: Are there any differences in breaking capacity or melting I²t between these parts?

A: No. Both parts have identical breaking capacity (35A at rated voltage) and melting I²t (0.044), ensuring equivalent protection characteristics in the circuit.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0034.6040 and 0034.6010 carry CCC, cURus, and VDE approvals, are ROHS3 compliant, and are REACH unaffected.

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

A: Both parts operate within the range of -40°C to 85°C, suitable for standard industrial and commercial applications.

Q: Are these parts available in different packaging options?

A: Both parts are supplied in bulk packaging. The mechanical package is identical: radial, can-style, vertical orientation for through-hole mounting.

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

A: No technical difference exists. Both are from the same manufacturer and series. Differences may relate to manufacturing date, inventory batch, or internal SCHURTER part numbering conventions, but electrical and mechanical performance is identical.
