Key Parameters

Substitute Part Grouping Explanation

The CH223DU qualifies as a direct substitute for the CH223B based on the following critical parameters:

• Fuse Size Compatibility: Both accept 22mm x 58mm cartridge fuses
• Current Rating: Both rated for 100 A
• Number of Circuits: Both feature 3-pole configuration
• Mounting Type: Both mount on DIN rail
• Termination: Both use screw terminal connections
• Fuse Type: Both accept cartridge-type fuses

The CH223DU operates at 700V, which exceeds the CH223B's 600V rating. In electrical systems, a component rated for higher voltage can safely replace one rated for lower voltage when all other parameters align. The CH223DU is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CH223DU is the direct equivalent for CH223B replacement. Selection is based on the following factors:

• Obsolescence: The CH223B is obsolete; the CH223DU is active and maintains current manufacturing support
• Electrical Compatibility: The CH223DU's 700V rating encompasses the CH223B's 600V operating range, ensuring safe operation in existing 600V circuits
• Mechanical Compatibility: Identical fuse size, mounting configuration, and terminal style enable direct installation without mechanical modification
• Regulatory Compliance: The CH223DU carries RoHS Compliant certification, meeting current environmental standards

Frequently Asked Questions (FAQ)

Q: Can CH223DU replace CH223B in a 600V circuit? A: Yes. The CH223DU is rated for 700V, which exceeds the 600V requirement. Higher voltage-rated components operate safely in lower-voltage applications.

Q: Are the physical dimensions identical? A: Yes. Both holders accept 22mm x 58mm cartridge fuses and mount identically on DIN rail with screw terminal connections.

Q: What is the difference in packaging? A: CH223B packaging is listed as standard; CH223DU is supplied in bulk packaging. This does not affect functional compatibility.

Q: Why is CH223B obsolete? A: Product obsolescence is determined by the manufacturer. The CH223DU represents the active equivalent in the CH series product line.

Q: Are there any circuit modifications required? A: No. The CH223DU is a direct mechanical and electrical substitute requiring no circuit or installation modifications.

Q: What certifications apply to the substitute? A: The CH223DU is RoHS Compliant. The CH223B certification status is not specified in available documentation.
