Key Parameters

Substitute Part Grouping Explanation

Substitution of the CH142BI is determined by the following critical parameters:

• Fuse size compatibility: 14mm x 51mm cartridge format
• Number of circuits: 2-circuit configuration
• Mounting interface: DIN rail mounting
• Termination method: Screw terminal connection
• Voltage and current rating envelope

The CH142DIU qualifies as a substitute based on matching fuse size, circuit count, mounting type, and termination style. The CH142DIU operates at higher voltage (700V) and current (50A) ratings, which are compatible with the 600V/40A application envelope of the CH142BI.

Parameter Comparison

Engineering Selection Recommendations

The CH142DIU is the direct substitute for the CH142BI. Both components share identical mechanical form factors, fuse accommodation specifications, and electrical interface characteristics. The CH142DIU is currently in active production status, whereas the CH142BI is obsolete. The CH142DIU carries RoHS compliance certification, providing regulatory advantage in new system designs and replacements. The higher voltage and current ratings of the CH142DIU (700V/50A) encompass the operational envelope of the CH142BI (600V/40A), ensuring functional compatibility in existing circuit configurations.

Frequently Asked Questions (FAQ)

Q: Can the CH142DIU directly replace the CH142BI in existing installations?

A: Yes. Both components accommodate identical 14mm x 51mm cartridge fuses, feature 2-circuit DIN rail mounting, and utilize screw terminal connections. The CH142DIU's higher voltage and current ratings are compatible with CH142BI applications.

Q: What is the physical compatibility between these fuse holders?

A: Both the CH142BI and CH142DIU are designed for the same fuse size (14mm x 51mm) and mounting interface (DIN rail). Mechanical installation dimensions and terminal spacing are equivalent.

Q: Does the CH142DIU require different fuses than the CH142BI?

A: No. Both holders accept the same 14mm x 51mm cartridge fuse format. Fuse selection should be based on the specific circuit protection requirements of the application.

Q: What is the difference in voltage and current ratings?

A: The CH142BI is rated for 600V/40A, while the CH142DIU is rated for 700V/50A. The CH142DIU's higher ratings provide additional operational margin and are suitable for applications originally designed for the CH142BI.

Q: Is the CH142DIU RoHS compliant?

A: Yes. The CH142DIU is RoHS compliant, whereas RoHS status is not specified for the obsolete CH142BI.

Q: Are the termination methods identical?

A: Yes. Both components use screw terminal connections for circuit integration.
