CWA24125P Equivalent & Substitute Parts

Part Overview

The CWA24125P is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This component is designed for AC load switching applications with a rated load current of 125 A and operates across input voltage ranges of 90–280 VAC with load voltages from 24–280 V. The part maintains Active product status and is RoHS Compliant. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and continuity of supply for applications requiring SPST-NO solid-state relay functionality with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CWA24125P are identified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 125 A nominal capacity
• Output Type: AC switching with zero-cross detection
• Package Form Factor: Hockey Puck chassis-mount configuration
• Termination Interface: Screw terminal connection
• Compliance Status: RoHS Compliant certification

The substitute part 84137181N (Crouzet, Series GN) meets these core substitution criteria. While the load voltage range differs (48–660 V versus 24–280 V) and input voltage specifications vary (20–265 VAC versus 90–280 VAC), both components maintain identical circuit topology, load current capacity, output switching characteristics, physical form factor, and termination method. These voltage differences reflect design variations within the same functional class and do not preclude substitution in applications where the substitute's voltage ratings encompass the system requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA24125P and 84137181N maintain Active product status and RoHS Compliant certification, ensuring regulatory compliance and ongoing manufacturer support. Selection between these components should be based on system voltage requirements:

• CWA24125P is suitable for applications with input control voltages between 90–280 VAC and load voltages between 24–280 V.
• 84137181N accommodates a broader load voltage range (48–660 V) and lower input voltage threshold (20 VAC minimum), making it applicable to systems requiring extended voltage operating windows.

Both components share identical load current capacity (125 A), circuit topology (SPST-NO), output switching behavior (AC, zero-cross), physical form factor (hockey puck), and termination method (screw terminal). The choice between these parts depends on whether the application's actual voltage parameters fall within the specified ranges of each component.

Frequently Asked Questions (FAQ)

Q: Can the 84137181N replace the CWA24125P in all applications?

A: Substitution is valid only when the application's input and load voltage requirements fall within the 84137181N's specified ranges (20–265 VAC input, 48–660 V load). If the system requires input voltages below 20 VAC or load voltages below 48 V, the CWA24125P is the appropriate choice.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both components use hockey puck form factor with chassis mount configuration and screw terminal termination, ensuring mechanical and electrical interface compatibility.

Q: Do both parts support zero-cross switching?

A: Yes. Both the CWA24125P and 84137181N feature AC output type with zero-cross detection, providing synchronized switching at AC voltage zero-crossing points.

Q: What is the significance of the different load voltage ranges?

A: The CWA24125P operates from 24–280 V, while the 84137181N operates from 48–660 V. These ranges define the minimum and maximum load voltages each relay can safely switch. Selection depends on the actual load voltage in the target application.

Q: Are both parts RoHS Compliant?

A: Yes. Both the CWA24125P and 84137181N carry RoHS Compliant certification and share the same ECCN (EAR99) and HTSUS (8536.49.0080) classifications.

Q: What is the load current capacity for both parts?

A: Both components are rated for 125 A continuous load current, providing equivalent current-switching capability.
