Key Parameters

Substitute Part Grouping Explanation

Substitution of the Mersen 30353R is determined by the following critical parameters:

• Voltage Rating: Must match or exceed 600V
• Number of Circuits/Poles: Must be 3-pole configuration
• Fuse Block Classification: Class CC fuse block type
• Mounting and Termination: Physical compatibility with existing installation
• Compliance Standards: ROHS3 compliance required

The Littelfuse L60030C3C qualifies as a substitute based on matching voltage rating (600V), 3-circuit configuration, cartridge fuse block design, and equivalent compliance certifications. Both parts are rated for identical voltage and circuit requirements, enabling direct functional replacement in Class CC fuse block applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Mersen 30353R and Littelfuse L60030C3C are active production components with ROHS3 compliance certification. Selection between these parts should be based on:

• Voltage and Circuit Requirements: Both parts satisfy 600V, 3-pole/circuit requirements
• Compliance Verification: Both maintain ROHS3 compliance status
• Inventory Availability: Primary part (908 units) and substitute (853 units) are both in stock
• Physical Installation Constraints: Verify mounting type and termination compatibility with existing equipment before substitution
• Current Rating Compatibility: Confirm that the 30 A rating of the L60030C3C aligns with circuit protection requirements

Frequently Asked Questions (FAQ)

Q: What makes the Littelfuse L60030C3C a valid substitute for the Mersen 30353R?

A: Both parts share identical voltage rating (600V) and 3-circuit configuration, which are the primary substitution criteria for Class CC fuse blocks. Both maintain active production status and ROHS3 compliance.

Q: Are there any physical differences between these parts that would affect installation?

A: The L60030C3C is specified as chassis mount with box lug termination and 30 A current rating. Verify that these specifications align with your equipment's mounting requirements and current protection needs before installation.

Q: Can I use the Littelfuse part as a direct replacement without modification?

A: Physical compatibility depends on your specific installation. Confirm mounting type, termination style, and current rating requirements match your application before substitution.

Q: What compliance standards apply to both parts?

A: Both the Mersen 30353R and Littelfuse L60030C3C are ROHS3 compliant. The L60030C3C additionally carries REACH Unaffected status and EAR99 ECCN classification.

Q: Which part should I select if both are available?

A: Selection should be based on existing equipment compatibility, current rating requirements, and mounting constraints. Both parts meet the core voltage and circuit specifications for Class CC fuse block applications.
