SC-1 Ceramic Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The SC-1 is a 1A ceramic cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 600VAC and 170VDC operation. This component is designed for electrical circuits requiring slow-blow response characteristics and requires a compatible fuse holder for installation. The part maintains active product status with 1077 units currently in stock. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC-1 are identified based on the following critical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 600 V (exact match required)
• Voltage Rating - DC: 170 V (exact match required)
• Fuse Type: Cartridge configuration
• Breaking Capacity: 100kA AC, 10kA DC (exact match required)
• Package / Case: Cartridge, Non-Standard (mechanical compatibility)
• Size / Dimension: 0.410" Dia x 1.310" L ±tolerance (physical fit in holder)
• Approval Agency: CE, CSA, UL certifications (regulatory compliance)

The 0SLC001.T from Littelfuse Inc. qualifies as a substitute based on matching electrical ratings, breaking capacity, and approval certifications. Minor variations in response time classification (Medium Blow vs. Slow Blow) and dimensional tolerances within the non-standard cartridge specification do not preclude substitution when holder compatibility is confirmed.

Parameter Comparison

Engineering Selection Recommendations

Both the SC-1 and 0SLC001.T maintain active product status and carry equivalent regulatory approvals (CE, CSA, UL). The 0SLC001.T includes additional QPL certification. Both components meet RoHS compliance requirements. Dimensional differences are minimal (0.004" diameter, 0.001" length variation) and fall within typical mechanical tolerances for non-standard cartridge fuse holders. The response time classification difference (Slow Blow vs. Medium Blow) reflects manufacturer curve definitions and does not indicate incompatibility for equivalent circuit protection applications. Selection between these parts should be based on holder compatibility verification and application-specific response time requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0SLC001.T replace the SC-1 in existing installations?

A: Yes, provided the fuse holder accommodates the dimensional tolerances. The 0.406" diameter and 1.311" length of the 0SLC001.T are within typical mechanical clearances for non-standard cartridge holders designed for the SC-1 specification.

Q: What is the significance of the response time difference (Slow Blow vs. Medium Blow)?

A: Response time classification indicates the fuse element's thermal response curve. Slow Blow and Medium Blow designations reflect manufacturer-specific curve definitions. Both parts carry identical breaking capacity ratings (100kA AC, 10kA DC) and are suitable for general electrical circuit protection at the specified 1A rating.

Q: Are both parts RoHS compliant?

A: Yes. The SC-1 is RoHS Compliant, and the 0SLC001.T is ROHS3 Compliant. Both meet current RoHS requirements.

Q: What approval certifications are required for this application?

A: Both parts carry CE, CSA, and UL certifications. The 0SLC001.T includes additional QPL certification. Verify that your application requirements align with the certifications provided by your selected part.

Q: Are dimensional differences critical for substitution?

A: Dimensional variations between the SC-1 (0.410" Dia x 1.310" L) and 0SLC001.T (0.406" Dia x 1.311" L) are minimal. Confirm that your fuse holder specification accommodates both dimensions before substitution.
