CWA4890 Equivalent & Substitute Parts

Part Overview

The CWA4890 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 90A and operates across a load voltage range of 48V to 660V. The device features zero-cross switching capability and screw terminal connections for industrial applications.

The CWA4890 maintains Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified to provide alternatives for procurement flexibility, inventory management, or when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA4890 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross switching
• Load Voltage Range: Must support 48V to 660V operation
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• Package / Case: Must be Hockey Puck form factor

The identified substitute parts meet these core electrical and mechanical requirements. Load current ratings may vary within acceptable operational ranges for the application category. Input voltage ranges may differ while maintaining compatibility with standard control circuit voltages.

Engineering Selection Recommendations

84134141 (Sensata-Crydom GN Series)

This substitute maintains identical input and load voltage specifications to the CWA4890 while providing a higher load current rating of 100A. Both components are manufactured by Sensata-Crydom and share ROHS3 compliance. The 84134141 is suitable for applications where the CWA4890 is unavailable and higher current capacity is acceptable within the system design.

84137141N (Crouzet GN Series)

This substitute is manufactured by Crouzet and provides equivalent load voltage and current specifications to the 84134141. The input voltage range is 20 ~ 265VAC, which encompasses the CWA4890 operating range. The 84137141N carries RoHS compliance and is packaged in a box format rather than bulk. This component is suitable for applications where cross-manufacturer substitution is acceptable and REACH compliance requirements differ from the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 84134141 directly replace the CWA4890 in existing designs?

A: Yes. Both components share identical load voltage ranges (48V to 660V), input voltage specifications (90 ~ 280VAC), circuit configuration (SPST-NO), output type (AC, zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form (hockey puck). The 84134141 has a higher load current rating (100A vs. 90A), which does not prevent substitution in applications designed for the CWA4890.

Q: What is the difference between the 84134141 and 84137141N?

A: Both parts have identical load current (100A) and load voltage specifications (48V to 660V). The primary differences are manufacturer (Sensata-Crydom vs. Crouzet), input voltage range (90 ~ 280VAC vs. 20 ~ 265VAC), RoHS certification level (ROHS3 vs. RoHS), REACH status (affected vs. unaffected), and packaging format (bulk vs. box). The 84137141N input voltage range is broader and includes lower voltage operation.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three components share identical mounting type (chassis mount), termination style (screw terminal), and package form (hockey puck). Physical installation and electrical connection methods are equivalent.

Q: Does the higher load current rating of the substitute parts affect circuit design?

A: No. The substitute parts are rated for higher load current (100A) than the CWA4890 (90A). This represents increased capability and does not require circuit redesign for applications operating within the CWA4890 current specifications.

Q: What compliance differences exist between these parts?

A: The CWA4890 and 84134141 are both ROHS3 compliant and REACH affected. The 84137141N is RoHS compliant and REACH unaffected. Selection should consider regulatory requirements specific to the end application and target market.
