Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CH141D are identified based on the following critical parameters that determine functional compatibility:

• Fuse size: 14mm x 51mm (0.551" Dia x 2.008" L)
• Mounting configuration: DIN rail single-circuit
• Voltage rating: 600V
• Termination method: Screw terminal
• Fuseholder type: Cartridge holder

The CB1451-1 from Altech Corporation meets these core mechanical and electrical compatibility requirements. While the current rating differs (50 A versus 40 A), both parts accommodate the same 14mm x 51mm cartridge fuse format and share identical mounting, voltage, and termination specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CH141D and CB1451-1 are classified as obsolete products. Selection between these parts should be based on:

• Circuit current requirements: The CH141D is rated for 40 A, while the CB1451-1 is rated for 50 A. Application-specific current demands determine which part is appropriate.
• Regulatory compliance: Both parts maintain REACH Unaffected status and EAR99 export classification, indicating equivalent compliance posture.
• Mechanical compatibility: Both parts are mechanically interchangeable within DIN rail installations designed for 14mm x 51mm cartridge fuses with screw terminal connections.
• Availability: Current inventory shows 763 units of CH141D and 830 units of CB1451-1 in stock.

Frequently Asked Questions (FAQ)

Q: Can CB1451-1 directly replace CH141D in all applications?

A: CB1451-1 is mechanically and electrically compatible with CH141D for DIN rail mounting and 14mm x 51mm cartridge fuse accommodation. The 50 A rating of CB1451-1 exceeds the 40 A rating of CH141D. Substitution is valid when the application circuit current does not exceed 40 A.

Q: What are the critical compatibility parameters for these fuse holders?

A: Fuse size (14mm x 51mm), voltage rating (600V), mounting type (DIN rail), number of circuits (1), and termination style (screw terminal) are the defining parameters for substitution eligibility.

Q: Are there packaging differences between CH141D and CB1451-1?

A: CH141D is supplied with standard packaging, while CB1451-1 is supplied in bulk packaging. Both parts are functionally identical in their electrical and mechanical specifications.

Q: Do both parts meet current regulatory requirements?

A: Both CH141D and CB1451-1 maintain REACH Unaffected status and are classified under ECCN EAR99, indicating equivalent regulatory standing for export and use.
