LINK003C.Z Equivalent & Substitute Parts

Part Overview

The LINK003C.Z is a 30 A, 600V cartridge fuse holder designed for DIN rail mounting with 3-circuit configuration. Manufactured by Littelfuse Inc. under the Up-LINK™ series, this component is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and new design implementations where this specification remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LINK003C.Z is determined by strict alignment of the following parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 600V (exact match required)
• Fuse Size: 0.394" Dia x 1.496" L / 10mm x 38mm (exact match required)
• Number of Circuits: 3 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Fuse Type: Cartridge (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The CHCC3DIU from Eaton - Bussmann Electrical Division meets all mandatory electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CHCC3DIU is the qualified substitute for the obsolete LINK003C.Z. Both components share identical electrical ratings (30 A, 600V), mechanical dimensions (10mm x 38mm cartridge), circuit configuration (3-circuit), and mounting interface (DIN rail). Both maintain ROHS3 compliance and EAR99 export classification.

The CHCC3DIU carries active product status, ensuring ongoing availability and supply chain continuity. Selection of this substitute eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing installations and new designs requiring this specification.

Frequently Asked Questions (FAQ)

Q: Can the CHCC3DIU be used as a direct replacement for the LINK003C.Z?

A: Yes. The CHCC3DIU meets all electrical and mechanical parameters: 30 A current rating, 600V voltage rating, 10mm x 38mm cartridge size, 3-circuit configuration, DIN rail mounting, and ROHS3 compliance. Physical and electrical compatibility is confirmed.

Q: What fuse types are compatible with these holders?

A: Both the LINK003C.Z and CHCC3DIU accept Class CC cartridge fuses in the 13/32" x 1-1/2" (10mm x 38mm) format at 30 A rating.

Q: Are there differences in termination between these parts?

A: The LINK003C.Z specifies screw terminal and pressure plate termination. The CHCC3DIU termination style is not specified in available data. Physical verification of terminal compatibility is recommended prior to installation in existing equipment.

Q: Does product status affect electrical performance?

A: No. The obsolete status of the LINK003C.Z reflects manufacturing discontinuation only. Electrical and mechanical performance specifications remain valid. The active status of the CHCC3DIU ensures future availability and supply security.

Q: Are both parts RoHS compliant?

A: Yes. Both the LINK003C.Z and CHCC3DIU are ROHS3 compliant, meeting current environmental and regulatory requirements.
