CWU2425P-10 Equivalent & Substitute Parts

Part Overview

The CWU2425P-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a rated load current of 25 A and operates across a voltage range of 24 V to 280 V. The part is currently in active production status and maintains RoHS compliance.

Equivalent and substitute parts are identified when they share the same functional circuit topology, load current rating, output type, termination style, and package configuration. This ensures direct compatibility in applications where the CWU2425P-10 is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWU2425P-10 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 25 A
• Output type must be AC or AC with zero-cross capability
• Load voltage range must encompass or match 24 V ~ 280 V
• Package must be hockey puck with screw terminal termination
• Mounting type must be chassis mount

The substitute part 84138013N (Crouzet GN+ series) meets these criteria. While the input voltage range differs slightly (20 ~ 265 VAC/DC versus 20 ~ 280 VAC, 20 ~ 48 VDC), the load voltage range of 12 V ~ 270 V provides functional compatibility for applications within the overlapping voltage window of 24 V ~ 270 V. Both parts maintain identical circuit topology, current rating, package configuration, and termination style.

Parameter Comparison

Engineering Selection Recommendations

Both the CWU2425P-10 and 84138013N are active production components with RoHS compliance certification. Selection between these parts should be based on application voltage requirements and input control signal specifications.

The CWU2425P-10 supports a broader input voltage range (20 ~ 280 VAC, 20 ~ 48 VDC) and load voltage ceiling (280 V), making it suitable for applications requiring operation at the upper voltage limits. The 84138013N provides zero-cross switching capability, which reduces EMI and is beneficial in noise-sensitive applications, though its load voltage range extends only to 270 V.

For applications operating within the overlapping voltage window (24 V ~ 270 V), both parts are functionally equivalent. Compliance requirements and supply chain availability should guide final selection.

Frequently Asked Questions (FAQ)

Q: Can the 84138013N replace the CWU2425P-10 in all applications?

A: The 84138013N is compatible with applications operating within the overlapping load voltage range of 24 V ~ 270 V. Applications requiring operation above 270 V load voltage must use the CWU2425P-10.

Q: What is the significance of zero-cross switching in the 84138013N?

A: Zero-cross switching synchronizes relay activation with the AC voltage zero-crossing point, reducing inrush current and electromagnetic interference. This feature is present in the 84138013N but not specified for the CWU2425P-10.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts use hockey puck packaging with chassis mount configuration and screw terminal termination. Physical compatibility is ensured for direct substitution in existing mechanical assemblies.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the CWU2425P-10 and 84138013N are RoHS compliant and carry ECCN EAR99 classification. Both are assigned HTSUS code 8536.49.0080.

Q: What input voltage range should be verified before substitution?

A: Verify that the control signal voltage supplied to the relay falls within the specified input range. The CWU2425P-10 accepts 20 ~ 280 VAC or 20 ~ 48 VDC. The 84138013N accepts 20 ~ 265 VAC/DC. Confirm compatibility with your control circuit before implementation.
