USCC3 Equivalent & Substitute Parts

Part Overview

The USCC3 is a 600V 30A 3-pole cartridge fuse holder manufactured by Mersen USA Newburyport-MA L.L.C. This component is classified as an active product and serves as a critical interface for Class CC fuse cartridges in electrical distribution systems. The part is ROHS3 compliant and maintains an active product status with substantial inventory availability. Identifying equivalent and substitute parts is necessary to ensure supply chain continuity, optimize procurement timelines, and maintain compatibility across similar electrical protection architectures.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the USCC3 is determined by strict alignment of the following electrical and mechanical parameters:

Voltage Rating: Both the main part and substitute must operate at 600V to ensure safe operation within the same electrical system architecture.

Current Rating: The 30A current rating is a critical specification that determines the thermal and magnetic characteristics of the fuse holder. Substitutes must match this rating exactly.

Number of Circuits: The 3-pole configuration is essential for three-phase electrical systems. Substitutes must maintain this circuit count.

Fuse Type and Compatibility: The USCC3 accommodates Class CC cartridge fuses with dimensions 0.394" Dia x 1.496" L (10mm x 38mm). Substitutes must support the same fuse cartridge standard.

Compliance and Product Status: Both the main part and substitutes must maintain active product status and ROHS3 compliance to ensure regulatory alignment and ongoing manufacturer support.

The LPSC0003Z from Littelfuse Inc. qualifies as a substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the USCC3 and LPSC0003Z maintain active product status and ROHS3 compliance, ensuring regulatory alignment and manufacturer support continuity. Selection between these parts should be based on:

Availability: The LPSC0003Z currently maintains higher inventory levels (1046 units) compared to the USCC3 (936 units), which may influence procurement timelines.

Manufacturer Preference: The USCC3 is the primary specification. The LPSC0003Z serves as a qualified substitute when the primary part is unavailable or when multi-source qualification is required.

Compliance Verification: Both parts meet ROHS3 requirements and are suitable for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can the LPSC0003Z directly replace the USCC3 in existing installations?

A: Yes, provided that the electrical system specifications match the documented parameters: 600V, 30A, 3-circuit configuration, and Class CC cartridge fuse compatibility. Physical mounting and termination compatibility must be verified against the specific installation requirements.

Q: What are the critical parameters that determine substitution eligibility?

A: Voltage rating (600V), current rating (30A), number of circuits (3), and fuse type (Class CC cartridge) are the primary determinants. These parameters must match exactly between the main part and any substitute.

Q: Are there any compliance differences between the USCC3 and LPSC0003Z?

A: Both parts are ROHS3 compliant and maintain active product status. No compliance differences exist based on the provided specifications.

Q: What is the significance of the Class CC fuse cartridge standard?

A: Class CC fuses are a standardized cartridge type with specific dimensions (0.394" Dia x 1.496" L) and electrical characteristics. Both the USCC3 and LPSC0003Z are designed to accommodate this standard, ensuring mechanical and electrical compatibility.

Q: How should mounting type differences be evaluated?

A: The LPSC0003Z is specified for DIN Rail mounting. Installation compatibility depends on whether the existing system supports DIN Rail mounting. Physical installation requirements must be verified before substitution.
