Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.7314 is determined by the following critical parameters:

• Current Rating: 800 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Style: Radial, Can, Vertical (exact match required)
• Physical Dimensions: 0.335" Dia x 0.335" H / 8.50mm x 8.50mm (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)

The substitute part 0034.6974 meets all critical electrical and mechanical parameters. Differences in Breaking Capacity (50A vs. 100A) and Melting I²t values (4.05 vs. 1.5) do not disqualify substitution, as these parameters remain within acceptable ranges for the specified current and voltage ratings. The substitute part offers expanded regulatory approvals (CCC, cURus, KC, VDE) compared to the original part (cULus).

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 0034.7314 and 0034.6974 are active production parts with ROHS3 compliance and equivalent electrical and mechanical specifications. The 0034.7314 carries cULus certification, suitable for applications requiring North American regulatory approval. The 0034.6974 provides broader international certifications (CCC, cURus, KC, VDE), making it preferable for global applications or markets requiring specific regional compliance. Selection should be based on the regulatory requirements of the target application and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 0034.6974 be used as a direct replacement for the 0034.7314?

A: Yes. Both parts share identical electrical ratings (800 mA, 250 V AC), response time (Slow Blow), mounting type (Through Hole), and physical dimensions (0.335" Dia x 0.335" H). They are mechanically and electrically interchangeable.

Q: What is the difference in Breaking Capacity between these parts?

A: The 0034.7314 has a Breaking Capacity of 50A, while the 0034.6974 has 100A. Both values exceed the rated current of 800 mA and are acceptable for this application category.

Q: How do the Melting I²t values differ, and does this affect substitution?

A: The 0034.7314 has a Melting I²t of 4.05, while the 0034.6974 has 1.5. Both values are within acceptable ranges for 800 mA slow-blow fuses and do not prevent substitution.

Q: Which part should I select for international applications?

A: The 0034.6974 is recommended for international applications due to its broader regulatory approvals (CCC, cURus, KC, VDE). The 0034.7314 is suitable for North American markets with cULus certification.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.335" Dia x 0.335" H (8.50mm x 8.50mm) and use the same radial, can-style vertical package, ensuring identical PCB footprint compatibility.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the same temperature range of -40°C to 85°C.
