Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CHCC2 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• 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: 2 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Fuse Type: Cartridge (exact match required)
• Termination Style: Screw Terminal (compatible if present)

The LPSC0002Z from Littelfuse Inc. meets all substitution criteria and is classified as an active product, providing a direct functional replacement for the obsolete CHCC2.

Parameter Comparison

Engineering Selection Recommendations

The LPSC0002Z is the direct equivalent substitute for the CHCC2. Both components share identical electrical ratings (30 A, 600V), mechanical dimensions (10mm x 38mm cartridge), circuit configuration (2-circuit), and mounting interface (DIN rail with screw terminal). The LPSC0002Z maintains active product status and full regulatory compliance (REACH Unaffected, EAR99 classification). The addition of pressure plate termination in the LPSC0002Z provides enhanced contact reliability without compromising backward compatibility. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or installation.

Frequently Asked Questions (FAQ)

Q: Can the LPSC0002Z directly replace the CHCC2 in existing installations?

A: Yes. The LPSC0002Z meets all electrical and mechanical specifications of the CHCC2, including current rating (30 A), voltage rating (600V), fuse size (10mm x 38mm), circuit count (2), mounting type (DIN rail), and termination style (screw terminal). Physical dimensions and electrical performance are identical.

Q: What is the difference between screw terminal and pressure plate termination?

A: Both termination methods provide electrical connection to the fuse holder. The LPSC0002Z includes both screw terminal and pressure plate options, offering flexibility in installation methods while maintaining compatibility with standard screw terminal applications.

Q: Are there any compliance or regulatory differences between these components?

A: No. Both the CHCC2 and LPSC0002Z share identical regulatory classifications: REACH Unaffected, EAR99 ECCN, and HTSUS code 8538.90.8180. Both are classified as Moisture Sensitivity Level 1 (Unlimited).

Q: Why is the CHCC2 listed as obsolete?

A: The CHCC2 is no longer manufactured by Eaton - Bussmann Electrical Division. The LPSC0002Z from Littelfuse Inc. is the active equivalent product available for new orders and ongoing supply.

Q: What fuse types are compatible with these holders?

A: The CHCC2 is specified for 5AG, 13/32" x 1-1/2" (Midget) fuses. The LPSC0002Z is specified for Class CC Fuses, 13/32" x 1-1/2". Both accept the same physical fuse dimensions (10mm x 38mm).
