Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD24125 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must support AC with zero-cross detection for compatible control behavior
• Load Current Rating: Must be rated for 125 A minimum to handle specified load requirements
• Package / Case: Must be hockey puck form factor to ensure mechanical compatibility with existing mounting infrastructure
• Termination Style: Must use screw terminal connections for direct integration with existing wiring
• Input Voltage Compatibility: Control voltage range must overlap with or encompass the 3 ~ 32 VDC specification
• Load Voltage Range: Must accommodate the application's AC voltage requirements

The substitute part 84137180N (Crouzet GN series) meets these core substitution criteria while offering an extended load voltage range suitable for higher-voltage AC applications.

Engineering Selection Recommendations

CWD24125 (Sensata-Crydom) is the primary selection for applications requiring load voltages in the 24 V to 280 V range with ROHS3 compliance. This part maintains active production status and is REACH Affected, making it suitable for regulated markets.

84137180N (Crouzet) serves as a functional equivalent for applications requiring extended load voltage operation up to 660 V. This substitute maintains identical circuit configuration, output type, load current rating, and mechanical form factor. The input voltage range (4 ~ 32 VDC) is compatible with standard control circuits. This part is RoHS Compliant and REACH Unaffected, offering alternative compliance positioning for specific supply chain requirements.

Both parts share identical load current capacity (125 A), circuit topology (SPST-NO), and physical form factor (hockey puck), ensuring direct functional substitution within their respective voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 84137180N replace the CWD24125 in all applications?

A: The 84137180N is functionally equivalent for applications operating within the overlapping voltage range (48 V to 280 V). Applications requiring load voltages below 48 V must use the CWD24125. Applications requiring load voltages above 280 V can use the 84137180N.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts use identical hockey puck form factor packaging with screw terminal connections and chassis mount configuration, ensuring direct mechanical substitution.

Q: What is the input voltage compatibility between these parts?

A: The CWD24125 accepts 3 ~ 32 VDC control input, while the 84137180N accepts 4 ~ 32 VDC. The 84137180N has a slightly higher minimum input threshold (4 VDC vs. 3 VDC). Both ranges are compatible with standard industrial control circuits.

Q: Do these parts have different compliance certifications?

A: The CWD24125 is ROHS3 Compliant and REACH Affected. The 84137180N is RoHS Compliant and REACH Unaffected. Selection should consider regional regulatory requirements and supply chain compliance obligations.

Q: What determines whether a substitute part is acceptable?

A: Substitution is valid when the alternative part maintains identical circuit configuration (SPST-NO), output type (AC with zero-cross), load current rating (125 A), package form factor (hockey puck), and termination style (screw terminal), while operating within the application's voltage requirements.
