Substitute Part Grouping Explanation

Substitution eligibility for the BK/SC-8 is determined by strict equivalence across the following critical parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating - AC: 600 V (exact match required)
• Voltage Rating - DC: 170 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity: 100kA AC, 10kA DC (exact match required)
• Package / Case: Cartridge, Non-Standard (exact match required)
• Size / Dimension: 0.410" Dia x 1.310" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

Only parts meeting all specified parameters are classified as parametric equivalents. The SC-8 designation identifies this product line within the Eaton - Bussmann Electrical Division SC series.

Parameter Comparison

Engineering Selection Recommendations

The SC-8 is a direct parametric equivalent to the BK/SC-8 and qualifies as a substitute part. Both parts are manufactured by Eaton - Bussmann Electrical Division, maintain active product status, and carry identical electrical and mechanical specifications. Both parts hold CE, CSA, and UL approvals and are RoHS compliant, ensuring regulatory compliance across applications. Selection between these parts may be based on inventory availability, lead time, or procurement source, as all technical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: What makes SC-8 a valid substitute for BK/SC-8? A: The SC-8 meets all critical electrical and mechanical parameters: 8A current rating, 600VAC/170VDC voltage ratings, ceramic cartridge construction, slow-blow response, 100kA AC/10kA DC breaking capacity, and identical physical dimensions (0.410" Dia x 1.310" L). Both parts are manufactured by the same supplier and hold identical regulatory approvals.

Q: Are there any compatibility concerns when substituting SC-8 for BK/SC-8? A: No compatibility concerns exist. Both parts require the same non-standard cartridge holder and are mechanically and electrically interchangeable. The holder and mounting configuration remain unchanged.

Q: Do both parts have the same regulatory certifications? A: Yes. Both BK/SC-8 and SC-8 carry CE, CSA, and UL approvals and are RoHS compliant, ensuring equivalent regulatory standing for all applications.

Q: What is the difference between BK/SC-8 and SC-8 part numbers? A: The part numbers represent the same product line within the Eaton - Bussmann Electrical Division SC series. The designation difference does not reflect any technical variation; both parts are parametrically identical.

Q: Can I use SC-8 in place of BK/SC-8 without circuit redesign? A: Yes. Since all electrical ratings, breaking capacity, response characteristics, and physical dimensions are identical, no circuit redesign is required. Direct substitution is permissible.
