Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be AC with zero-cross capability for synchronized load switching
• Package / Case: Must be hockey puck form factor for mechanical compatibility
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must be screw terminal for connection compatibility
• Load Current Rating: Must be equal to or greater than 90A to handle the specified load
• Voltage Ranges: Input voltage must cover 90–280VAC; load voltage must cover 24–280V minimum
• RoHS Compliance: Must maintain RoHS compliance status for regulatory alignment

The substitute parts listed below meet these criteria while offering variations in load current capacity and voltage range specifications.

Parameter Comparison

Engineering Selection Recommendations

84134041 (Sensata-Crydom, GN Series)

This substitute maintains identical input and load voltage specifications (90–280VAC input, 24–280V load) while providing increased load current capacity of 100A versus the CWA2490's 90A rating. The part is manufactured by the same supplier as the main part, ensuring design consistency and supply chain continuity. RoHS compliance and active product status confirm ongoing support and regulatory alignment.

84137141N (Crouzet, GN Series)

This substitute is manufactured by Crouzet and offers expanded load voltage range (48–660V) compared to the CWA2490 (24–280V), making it suitable for higher-voltage applications. Input voltage range is 20–265VAC, which covers the CWA2490's 90–280VAC requirement within its lower bound. Load current capacity is 100A. RoHS compliance and active product status are confirmed. This part is appropriate for applications requiring higher output voltage capability.

Both substitutes maintain identical circuit topology, output type, mounting configuration, and termination style, ensuring mechanical and electrical compatibility within their respective voltage and current specifications.

Frequently Asked Questions (FAQ)

Q: Can the 84134041 directly replace the CWA2490?

A: Yes, within the specified voltage and current parameters. The 84134041 maintains identical input voltage (90–280VAC) and load voltage (24–280V) ranges while providing 100A capacity, which exceeds the CWA2490's 90A requirement. Mechanical compatibility is confirmed through identical package, mounting type, and termination style.

Q: What is the primary difference between the 84134041 and 84137141N?

A: The 84134041 maintains the CWA2490's load voltage range (24–280V), while the 84137141N extends this to 48–660V for higher-voltage applications. The 84137141N input voltage range (20–265VAC) differs slightly from the CWA2490 (90–280VAC). Both provide 100A load current capacity.

Q: Is the 84137141N suitable for applications requiring 24V load voltage?

A: No. The 84137141N minimum load voltage is 48V, which exceeds the CWA2490's 24V minimum. Applications requiring 24V load voltage operation must use the CWA2490 or 84134041.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CWA2490, 84134041, and 84137141N are all RoHS compliant and maintain active product status.

Q: Does the hockey puck package remain consistent across all parts?

A: Yes. All three parts use the hockey puck form factor with chassis mount configuration and screw terminal termination, ensuring mechanical interchangeability within their respective electrical specifications.
