SC-5 Ceramic Cartridge Fuse 5A 600VAC/170VDC Equivalent & Substitute Parts

Part Overview

The SC-5 is a ceramic cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 5A at 600VAC and 170VDC. This slow-blow fuse cartridge requires a holder for installation and is designed for electrical and industrial applications. The part is currently active in production with 1074 units in stock. Substitute parts may be required due to supply chain considerations, inventory availability, or application-specific performance characteristics while maintaining equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-5 is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating - AC: 600 V (exact match required)
• Voltage Rating - DC: 170 V (exact match required)
• Breaking Capacity @ Rated Voltage: 100kA AC, 10kA DC (exact match required)
• Package / Case: Cartridge, Non-Standard (exact match required)
• Mounting Type: Requires Holder (exact match required)

The Littelfuse 0SLC005.T meets all critical electrical parameters and mechanical specifications. While the response time differs (Medium Blow vs. Slow Blow), the part maintains full electrical equivalence and is approved by the same regulatory agencies (CE, CSA, UL). Physical dimensions are within acceptable tolerance for holder compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SC-5 and 0SLC005.T are active production parts with full regulatory compliance. Selection between these parts should be based on the following factors:

SC-5 (Eaton - Bussmann): Primary choice for applications requiring slow-blow response characteristics. Maintains ceramic construction and is RoHS compliant. Approved by CE, CSA, and UL.

0SLC005.T (Littelfuse): Suitable for applications where medium-blow response is acceptable. Offers additional QPL approval and ROHS3 compliance. Physical dimensions are within tolerance for standard holder compatibility.

Both parts share identical electrical ratings (5A, 600VAC, 170VDC) and breaking capacity (100kA AC, 10kA DC), ensuring functional equivalence in circuits designed for these specifications. Holder compatibility should be verified for the specific application, as both use non-standard cartridge packages.

Frequently Asked Questions (FAQ)

Q: Can the 0SLC005.T replace the SC-5 in all applications?

A: The 0SLC005.T is electrically equivalent to the SC-5 across all critical parameters: current rating, voltage ratings, and breaking capacity. However, the response time differs (Medium Blow vs. Slow Blow). Applications sensitive to response time characteristics should be evaluated before substitution.

Q: Are the physical dimensions compatible with the same holder?

A: The SC-5 measures 0.410" Dia x 1.310" L, while the 0SLC005.T measures 0.406" Dia x 1.311" L. These dimensions are within acceptable tolerance for standard non-standard cartridge holders. Physical fit should be confirmed for the specific holder model in use.

Q: What regulatory approvals apply to both parts?

A: Both the SC-5 and 0SLC005.T carry CE, CSA, and UL approvals. The 0SLC005.T additionally holds QPL approval. Both are RoHS compliant (SC-5: RoHS Compliant; 0SLC005.T: ROHS3 Compliant).

Q: What is the difference between Slow Blow and Medium Blow response times?

A: Response time classification indicates how quickly the fuse element melts under overcurrent conditions. Slow Blow fuses tolerate temporary inrush currents before opening, while Medium Blow fuses respond faster to sustained overcurrent. Application requirements determine which response time is appropriate.

Q: Are both parts currently in stock?

A: Yes. The SC-5 has 1074 units in stock, and the 0SLC005.T has 1195 units in stock, both as new original inventory.
