Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD4890H is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC with zero-cross detection
• Input voltage range must accommodate 4 – 32 VDC
• Load current rating must be 90 A
• Mounting type must be chassis mount
• Package must be hockey puck configuration
• Termination must be screw terminal

The substitute part 84138150N (Crouzet, GN+ series) meets all mandatory functional and mechanical requirements. The load voltage range of the substitute (24 – 500 V) is a subset of the main part's range (48 – 660 V), making it suitable for applications operating within the 24 – 500 V window. Both parts share identical input voltage, load current, circuit topology, and physical form factor specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD4890H and 84138150N are active production components with RoHS compliance certification. Selection between these parts should be based on load voltage requirements. The CWD4890H supports the full 48 – 660 V range and is the primary specification. The 84138150N is functionally equivalent for applications with load voltages between 24 – 500 V. Both parts maintain identical control input specifications (4 – 32 VDC), load current capacity (90 A), and physical form factor, ensuring direct mechanical and electrical compatibility within the specified voltage window.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N substitute for the CWD4890H in all applications?

A: The 84138150N is functionally equivalent only for applications where the load voltage operates within the 24 – 500 V range. Applications requiring load voltages above 500 V or below 24 V must use the CWD4890H.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both parts use the hockey puck package configuration with chassis mount design and screw terminal termination, ensuring identical mechanical compatibility.

Q: Do both parts require the same control input voltage?

A: Yes. Both the CWD4890H and 84138150N operate with identical input voltage specifications of 4 – 32 VDC.

Q: What is the load current capacity for both parts?

A: Both parts are rated for 90 A load current.

Q: Are both parts RoHS compliant?

A: Yes. Both the CWD4890H and 84138150N meet RoHS compliance requirements.

Q: What is the key difference between these two parts?

A: The primary difference is the load voltage operating range. The CWD4890H supports 48 – 660 V, while the 84138150N supports 24 – 500 V. All other electrical and mechanical specifications are identical.
