Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWU2425P is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current Rating: Must be rated for 25A minimum to handle specified loads
• Load Voltage Range: Must encompass or exceed the 24V to 280V operating window
• Package Type: Must be hockey puck form factor to ensure mechanical fit in existing designs
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must use screw terminal connections
• Output Type: Must be AC with zero-cross switching capability

The substitute part 84138013N (Crouzet GN+ series) meets these criteria with compatible electrical ratings and identical mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWU2425P and 84138013N are active production components with current availability. The CWU2425P maintains RoHS3 certification, while the 84138013N holds RoHS compliance status. Selection between these parts should be based on:

• Supply chain availability: CWU2425P has 1114 units in stock; 84138013N has 723 units available
• Regulatory requirements: Applications requiring RoHS3 specifically should prioritize CWU2425P
• Voltage margin requirements: Applications operating near 270V should confirm compatibility with 84138013N's 270V upper load limit versus CWU2425P's 280V rating
• Input voltage specifications: Confirm system input voltage falls within the 20 ~ 265VAC/DC range for 84138013N

Both components share identical circuit configuration, current rating, package form factor, and termination methodology, confirming functional equivalence within specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can 84138013N directly replace CWU2425P in existing installations?

A: Yes, provided the application load voltage does not exceed 270V and input voltage remains within the 20 ~ 265VAC/DC range. Both components are SPST-NO hockey puck relays with 25A ratings, screw terminal connections, and chassis mount configurations.

Q: What is the voltage difference between these parts?

A: The CWU2425P supports load voltages up to 280V, while 84138013N is rated to 270V. For applications operating between 270V and 280V, CWU2425P is the appropriate selection. The input voltage range for 84138013N extends to 265VAC/DC compared to CWU2425P's 280VAC/DC maximum.

Q: Are the physical dimensions identical?

A: Both components use the hockey puck package type with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility in standard mounting applications.

Q: What compliance certifications apply to each part?

A: CWU2425P holds RoHS3 compliance and is REACH Affected. 84138013N is RoHS Compliant and REACH Unaffected. Applications subject to RoHS3 requirements should specify CWU2425P.

Q: Do both relays support zero-cross switching?

A: Yes, both CWU2425P and 84138013N feature AC output with zero-cross switching capability, providing identical control characteristics for AC load applications.
