CWA2425 Equivalent & Substitute Parts

Part Overview

The CWA2425 is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) with a hockey puck form factor. This component is designed for AC load switching applications with input voltage range of 90–280VAC and output load voltage range of 24–280V at 25A capacity. The device features zero-cross switching for AC output control and screw terminal connections for chassis-mount installation.

The CWA2425 maintains Active product status with full ROHS3 compliance and REACH affected designation. Identifying equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory alternatives, and maintain design compatibility across manufacturing batches and procurement cycles.

Substitute Part Grouping Explanation

Substitution eligibility for the CWA2425 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross switching for synchronized load control
• Load Current Rating: Must be rated for 25A minimum
• Load Voltage Range: Must accommodate 24–280V output specification
• Package / Case: Must be hockey puck form factor for mechanical compatibility
• Mounting Type: Must support chassis mount installation
• Termination Style: Must use screw terminal connections

The substitute part 84137011N (Crouzet, GN series) meets all mandatory equivalence criteria. While input voltage range differs (20–265VAC versus 90–280VAC), the substitute's input specification encompasses the lower end of the main part's range and remains within acceptable operational parameters for this product category. All other electrical and mechanical specifications align precisely with the CWA2425.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA2425 and 84137011N maintain Active product status, ensuring continued manufacturer support and availability. The CWA2425 carries ROHS3 compliance with REACH affected designation, while the 84137011N is RoHS compliant with REACH unaffected status. Selection between these parts should be based on regulatory requirements specific to the end application and regional compliance obligations.

The CWA2425 is currently in stock with 1119 units available in bulk packaging. The 84137011N substitute is available with 1099 units in box packaging. Both components share identical electrical performance characteristics for AC load switching at 25A with zero-cross output control.

Frequently Asked Questions (FAQ)

Q: Can the 84137011N replace the CWA2425 in existing designs?

A: Yes. Both components are SPST-NO solid-state relays with identical circuit configuration, output type, load current rating, load voltage range, mounting type, termination style, and package form factor. The electrical performance and mechanical interface are equivalent.

Q: What is the significance of the input voltage range difference?

A: The CWA2425 accepts 90–280VAC input, while the 84137011N accepts 20–265VAC input. The substitute's range covers the lower portion of the main part's specification. For applications operating within the 20–265VAC window, both parts are functionally equivalent. Applications requiring input voltages above 265VAC must use the CWA2425.

Q: Are there compliance differences between these parts?

A: The CWA2425 is ROHS3 compliant and REACH affected. The 84137011N is RoHS compliant and REACH unaffected. Compliance selection depends on the regulatory framework applicable to the end product and its intended market.

Q: Do both parts use the same termination method?

A: Yes. Both the CWA2425 and 84137011N use screw terminal connections, ensuring identical installation procedures and wiring compatibility.

Q: What is the hockey puck package form factor?

A: The hockey puck is a cylindrical chassis-mount package commonly used for solid-state relays. Both parts use this identical form factor, ensuring mechanical compatibility in existing mounting configurations.
