Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.6983 are classified based on electrical and mechanical parameter alignment:

Parametric Equivalent Classification: Parts sharing identical current rating (6.3 A), voltage rating (250 V AC), response time (Slow Blow), mounting type (Through Hole), fuse type (Board Mount), and package configuration (Radial, Can, Vertical) with matching physical dimensions and operating temperature range.

Similar Manufacturer Classification: Parts meeting all core electrical parameters and mechanical mounting requirements with minor dimensional or performance characteristic variations within acceptable tolerance for board mount fuse applications.

The following parameters determine substitution eligibility:

Current Rating: 6.3 A (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 Configuration: Radial, Can, Vertical (exact match required)
Physical Dimensions: 8.50mm diameter (exact match required)
Operating Temperature: -40°C ~ 85°C (exact match required)

Engineering Selection Recommendations

SCHURTER 0034.7323 (Parametric Equivalent): This part maintains identical electrical ratings and physical dimensions as the primary part. Both are ROHS3 compliant and active products. The primary distinction is the breaking capacity (50A versus 100A) and melting I²t value (287 versus 262). Selection of this substitute is appropriate when application requirements align with the lower breaking capacity specification and the MSTU 250 series characteristics are acceptable. Approval agency certification differs (cULus only versus CQC, cURus, PSE/JET, VDE), requiring verification against specific regional compliance mandates.

Littelfuse 38216300000 (Similar Manufacturer): This part satisfies all core electrical parameters and mounting requirements with active product status and ROHS3 compliance. The height dimension is 0.315" (8.00mm) versus 0.335" (8.50mm), representing a 0.50mm reduction. Breaking capacity matches the primary part at 100A. Melting I²t is 148.84, lower than both SCHURTER options. This part carries broader approval agency certifications (CQC, cURus, KC, PSE/JET, SEMKO, VDE). Selection is appropriate when the reduced height dimension accommodates board layout constraints and the TR5® 382 series performance characteristics meet application requirements.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.7323 be used as a direct replacement for SCHURTER 0034.6983?

A: Both parts share identical current rating (6.3 A), voltage rating (250 V AC), response time (Slow Blow), mounting type (Through Hole), package configuration (Radial, Can, Vertical), and physical dimensions (8.50mm x 8.50mm). The breaking capacity differs (50A versus 100A) and approval certifications vary. Direct substitution is permissible when application requirements do not exceed 50A breaking capacity and regional compliance requirements align with cULus certification.

Q: What is the primary dimensional difference between the Littelfuse 38216300000 and SCHURTER 0034.6983?

A: The Littelfuse part has a height of 0.315" (8.00mm) compared to 0.335" (8.50mm) for the SCHURTER part. The diameter remains identical at 0.335" (8.50mm). This 0.50mm height reduction may affect board layout and component spacing considerations.

Q: Are all three parts ROHS3 compliant?

A: Yes, all three parts—SCHURTER 0034.6983, SCHURTER 0034.7323, and Littelfuse 38216300000—are ROHS3 compliant with active product status.

Q: Which part has the highest breaking capacity?

A: Both SCHURTER 0034.6983 and Littelfuse 38216300000 have a breaking capacity of 100A at rated voltage. SCHURTER 0034.7323 has a breaking capacity of 50A.

Q: Do all parts operate within the same temperature range?

A: Yes, all three parts operate within the identical temperature range of -40°C to 85°C.

Q: What approval agencies certify the Littelfuse 38216300000?

A: The Littelfuse 38216300000 carries certifications from CQC, cURus, KC, PSE/JET, SEMKO, and VDE, providing broader regional compliance coverage than the SCHURTER 0034.6983 (CQC, cURus, PSE/JET, VDE).
