CWA2490-10 Equivalent & Substitute Parts

Part Overview

The CWA2490-10 is a solid-state relay (SSR) manufactured by Sensata Technologies, 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 90 A and input voltage range of 90–280 VAC. The part is currently active in production and RoHS compliant.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters, including circuit topology, load current rating, voltage specifications, termination style, and physical package format. The CWA2490-10 operates within specific voltage and current boundaries that define the scope of acceptable substitutes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA2490-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Load Current Rating: Must be rated for 90 A minimum to handle the specified load
• Voltage - Load Range: Must accommodate the 24–280 V operating window
• Package / Case: Must be hockey puck format to ensure mechanical compatibility with existing mounting infrastructure
• Termination Style: Must use screw terminal connections for direct integration
• Mounting Type: Must support chassis mount configuration

The substitute part 84138153N (Crouzet GN+ series) meets these criteria with the following alignment:

• Identical circuit topology (SPST-NO, 1 Form A)
• Equivalent load current rating (90 A)
• Extended load voltage range (24–500 V, which encompasses the 24–280 V requirement)
• Matching package format (hockey puck)
• Identical termination style (screw terminal)
• Compatible mounting type (chassis mount)
• RoHS compliant status maintained

Parameter Comparison

Engineering Selection Recommendations

Both the CWA2490-10 and 84138153N are active production components with RoHS compliance certification. Selection between these parts should be based on application-specific requirements:

The CWA2490-10 operates within a defined input voltage window of 90–280 VAC and load voltage range of 24–280 V. The 84138153N provides an extended load voltage capability (24–500 V) and broader input voltage flexibility (20–260 VAC/DC), including DC input support. The 84138153N also incorporates zero-cross switching functionality, which may provide additional benefits in AC load applications by reducing electromagnetic interference.

Both components maintain identical load current capacity (90 A), circuit topology (SPST-NO), package format (hockey puck), and termination method (screw terminal). Mechanical and electrical integration points are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 84138153N (Crouzet) directly replace the CWA2490-10 (Sensata) in existing applications?

A: Yes, the 84138153N meets all critical substitution parameters: identical SPST-NO circuit configuration, 90 A load current rating, hockey puck package format, screw terminal termination, and chassis mount compatibility. The extended voltage ratings of the 84138153N (24–500 V load, 20–260 VAC/DC input) encompass the CWA2490-10 operating range, ensuring functional compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are input voltage range (CWA2490-10: 90–280 VAC; 84138153N: 20–260 VAC/DC) and load voltage capability (CWA2490-10: 24–280 V; 84138153N: 24–500 V). The 84138153N includes zero-cross switching functionality, which the CWA2490-10 does not specify. Both parts are RoHS compliant and active in production.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both components use the hockey puck package format with chassis mount configuration and screw terminal connections. Physical compatibility is maintained for direct mechanical substitution.

Q: Do both parts support the same load current?

A: Yes, both the CWA2490-10 and 84138153N are rated for 90 A load current.

Q: What is the significance of zero-cross switching in the 84138153N?

A: Zero-cross switching is a control feature that synchronizes relay activation with the AC voltage waveform zero-crossing point. This reduces inrush current and electromagnetic interference in AC load applications. The CWA2490-10 does not specify this feature.
