Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD48125P-10 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 125A
• Input voltage range must be 4 ~ 32VDC
• Package type must be Hockey Puck
• Termination style must be Screw Terminal
• Mounting type must be Chassis Mount
• Output type must be AC compatible

The substitute part 84138180N (Crouzet GN+ series) meets these core requirements. However, the load voltage range differs: the substitute supports 24V ~ 500V versus the main part's 48V ~ 660V range. This difference must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD48125P-10 and 84138180N are active production components with RoHS compliance. Selection between these parts must be based on load voltage requirements:

• Use CWD48125P-10 for applications requiring load voltages up to 660V
• Use 84138180N for applications with load voltages up to 500V

The Crouzet 84138180N includes zero-cross switching functionality, which may provide additional benefits in certain AC switching applications. Both parts share identical input voltage ranges, current ratings, and mechanical form factors, ensuring compatibility in chassis-mounted installations with screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can 84138180N replace CWD48125P-10 in all applications?

A: Substitution is valid only when the application load voltage does not exceed 500V. The CWD48125P-10 supports higher load voltages (up to 660V), making it the required choice for high-voltage applications.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts use hockey puck packaging with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility in existing installations.

Q: What is the significance of zero-cross switching in the Crouzet part?

A: Zero-cross switching is a feature provided by the 84138180N. This parameter is specified in the product data but does not affect substitution eligibility based on the core electrical and mechanical criteria.

Q: Do both parts meet the same compliance standards?

A: Both CWD48125P-10 and 84138180N are RoHS compliant and carry ECCN EAR99 classification, meeting equivalent regulatory requirements.

Q: What input voltage range applies to both parts?

A: Both parts accept 4 ~ 32VDC input control voltage, ensuring compatibility with standard industrial control circuits.
