Equivalent & Substitute Parts for BP/SC-15

Part Overview

The BP/SC-15 is a 15 A ceramic cartridge fuse rated for 600 V AC and 170 V DC operation, manufactured by Eaton - Bussmann Electrical Division as part of the SC series. This component is designed for applications requiring slow-blow response characteristics and is approved by CE, CSA, and UL standards. The BP/SC-15 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BP/SC-15 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Current Rating: 15 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: 100 kA AC, 10 kA DC (exact match required)
• Physical Dimensions: 0.410" Dia x 1.310" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Eaton - Bussmann Electrical Division within the SC series.

Parameter Comparison

Engineering Selection Recommendations

The BP/SC-15 is discontinued and should be replaced with either BK/SC-15 or SC-15 for new procurement and system maintenance. Both substitute parts maintain full parametric equivalence with the original component across all electrical and mechanical specifications.

BK/SC-15 and SC-15 are both active products with current availability. Both parts carry identical certifications (CE, CSA, UL) and meet the same breaking capacity requirements. The primary distinction between these substitutes is packaging: BK/SC-15 is supplied in bulk packaging, while SC-15 is also supplied in bulk packaging. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Selection between BK/SC-15 and SC-15 should be based on procurement requirements, inventory availability, and supplier lead times, as both parts are functionally and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can BK/SC-15 or SC-15 be used as direct replacements for BP/SC-15?

A: Yes. Both BK/SC-15 and SC-15 are parametric equivalents to BP/SC-15. All three parts share identical electrical ratings (15 A, 600 V AC, 170 V DC), response characteristics (slow blow), breaking capacity (100 kA AC, 10 kA DC), physical dimensions (0.410" Dia x 1.310" L), and approval certifications (CE, CSA, UL).

Q: What is the difference between BP/SC-15, BK/SC-15, and SC-15?

A: The three parts are electrically and mechanically identical. The primary differences are product status and RoHS compliance level. BP/SC-15 is discontinued; BK/SC-15 and SC-15 are active products. BP/SC-15 is RoHS compliant, while BK/SC-15 and SC-15 are ROHS3 compliant.

Q: Do these fuses require a specific holder?

A: Yes. All three parts (BP/SC-15, BK/SC-15, and SC-15) are cartridge fuses that require a holder for installation. The non-standard cartridge dimensions (0.410" Dia x 1.310" L) must be matched with a compatible SC series fuse holder.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All three parts carry identical certifications: CE, CSA, and UL. Both active substitutes (BK/SC-15 and SC-15) are REACH unaffected and ROHS3 compliant, meeting current regulatory requirements.

Q: Which substitute should I select for new designs or procurement?

A: Either BK/SC-15 or SC-15 is suitable. Both are active products with full parametric equivalence. Selection should be based on packaging requirements, supplier availability, and lead times.
