CHCC3DI Equivalent & Substitute Parts Reference

Part Overview

The CHCC3DI is a 30 A, 600V cartridge fuse holder designed for DIN rail mounting with 3-circuit configuration. Manufactured by Eaton - Bussmann Electrical Division, this component is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and component sourcing in applications requiring 30 A, 600V cartridge fuse protection on DIN rail installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CHCC3DI is determined by strict equivalence across the following critical 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)

The CHCC3DIU qualifies as a direct substitute because it maintains identical electrical ratings, mechanical dimensions, circuit configuration, and mounting interface. The transition from obsolete to active product status, combined with maintained compatibility with Class CC fuses (13/32" x 1-1/2"), confirms functional equivalence for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The CHCC3DIU is the direct substitute for the obsolete CHCC3DI. Selection is based on:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring continued availability and supply chain reliability
• RoHS3 compliance of the substitute part, indicating adherence to current environmental standards
• Maintained regulatory classification (REACH Unaffected, EAR99) ensuring no additional compliance barriers
• Same tariff classification (HTSUS 8538.90.8180) confirming equivalent product category

The CHCC3DIU provides a direct replacement path for applications currently using the CHCC3DI, with no design modifications or system reconfiguration required.

Frequently Asked Questions (FAQ)

Q: Can the CHCC3DIU directly replace the CHCC3DI without modification?

A: Yes. The CHCC3DIU maintains identical current rating (30 A), voltage rating (600V), fuse size (10mm x 38mm), circuit count (3), and DIN rail mounting interface. No design changes are necessary.

Q: What is the primary reason for substitution?

A: The CHCC3DI is obsolete. The CHCC3DIU is the active equivalent from the same manufacturer, ensuring continued component availability and supply chain continuity.

Q: Are there packaging differences between the two parts?

A: Yes. The CHCC3DI is packaged as specified in the original documentation, while the CHCC3DIU is supplied in bulk packaging. This affects order quantities and logistics but does not impact electrical or mechanical performance.

Q: Do both parts support the same fuse types?

A: Both parts accommodate cartridge fuses in the 10mm x 38mm size. The CHCC3DIU explicitly references Class CC fuses (13/32" x 1-1/2"), which are compatible with the specified fuse dimensions.

Q: Are there compliance differences?

A: The CHCC3DIU includes RoHS3 compliance certification, reflecting current environmental standards. Both parts maintain REACH Unaffected status and EAR99 export classification, with no additional compliance barriers introduced by substitution.
