Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.6946 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Equivalence Criteria:

• Current Rating: 1.25 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Size / Dimension: 0.335" Dia x 0.335" H / 8.50mm x 8.50mm (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)

All substitute parts listed meet these criteria and are manufactured by SCHURTER Inc. Variations in Breaking Capacity, Melting I²t, and specific approval agencies are noted but do not preclude substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

0034.6916 (Primary Equivalent): This part is a direct parametric equivalent to the 0034.6946. Both components share identical electrical ratings (1.25A, 250VAC), response characteristics (Slow Blow), mechanical form factor (Radial, Can, Vertical, 8.50mm x 8.50mm), and performance specifications (100A breaking capacity, 6.3 Melting I²t). Both maintain active product status and full compliance with CCC, cURus, KC, PSE/JET, and VDE certifications. This substitute provides the highest level of functional interchangeability with superior inventory availability (15,217 units in stock versus 1,104 units for the main part).

0034.7116 and 0034.7216 (Functional Equivalents): These parts maintain identical electrical ratings, response time, and mechanical dimensions as the 0034.6946. Both are manufactured in the MSTU 250 series with active product status and ROHS3 compliance. The primary difference is reduced Breaking Capacity (50A versus 100A) and increased Melting I²t (7.93 versus 6.3). These parts are suitable for applications where the lower breaking capacity meets circuit protection requirements. Approval agency coverage is limited to cULus certification compared to the broader certification portfolio of the main part and 0034.6916.

All substitute parts maintain the required operating temperature range (-40°C ~ 85°C) and are REACH Unaffected with identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can 0034.6916 be used as a direct replacement for 0034.6946? A: Yes. The 0034.6916 is a direct parametric equivalent with identical current rating (1.25A), voltage rating (250VAC), response time (Slow Blow), mechanical package (Radial, Can, Vertical, 8.50mm x 8.50mm), and performance specifications (100A breaking capacity, 6.3 Melting I²t). Both parts carry the same certifications and maintain active product status.

Q: What is the difference between 0034.6916 and 0034.7116? A: The primary differences are Breaking Capacity (0034.6916: 100A; 0034.7116: 50A) and Melting I²t (0034.6916: 6.3; 0034.7116: 7.93). Both share identical electrical ratings, response time, and mechanical dimensions. The 0034.7116 is suitable for applications with lower breaking capacity requirements.

Q: Are 0034.7116 and 0034.7216 interchangeable with each other? A: Yes. Both parts are manufactured in the MSTU 250 series with identical electrical ratings (1.25A, 250VAC), response time (Slow Blow), mechanical package (Radial, Can, Vertical, 8.50mm x 8.50mm), Breaking Capacity (50A), and Melting I²t (7.93). The primary difference is inventory availability.

Q: Do all substitute parts meet the same safety certifications as the main part? A: The 0034.6916 carries the same full certification portfolio (CCC, cURus, KC, PSE/JET, VDE) as the 0034.6946. The 0034.7116 and 0034.7216 carry cULus certification, which is a subset of the main part's certifications. Application requirements should determine if this reduced certification scope is acceptable.

Q: Can these fuses be used in applications requiring 100A breaking capacity? A: The 0034.6946 and 0034.6916 are rated for 100A breaking capacity and are suitable for such applications. The 0034.7116 and 0034.7216 are rated for 50A breaking capacity and should not be used in applications requiring higher breaking capacity.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (0034.6916, 0034.7116, 0034.7216) are ROHS3 Compliant and REACH Unaffected, matching the environmental compliance status of the main part.
