Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA2410H is determined by the following criteria:

Circuit configuration must remain SPST-NO (1 Form A) to maintain functional equivalence in single-pole, normally-open switching applications. Output type must be AC with zero-cross detection to preserve load control characteristics. Load current rating must be rated for minimum 10A to ensure safe operation under specified conditions. Load voltage range must encompass the 24–280V specification. Mounting type and package form factor must be chassis mount hockey puck to ensure mechanical compatibility with existing installations. Termination style must be screw terminal for connection compatibility. RoHS compliance status must be maintained for regulatory alignment.

The substitute part 84137001N (Crouzet, GN series) meets these criteria with the following considerations: input voltage range is 20–265VAC, which provides coverage across the primary operating window of the main part, though the lower bound differs. All other electrical and mechanical parameters align with the CWA2410H specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA2410H and 84137001N are active production components with RoHS compliance certification, meeting current regulatory requirements. Selection between these parts should be based on application-specific input voltage requirements. The CWA2410H operates across 90–280VAC input range, while the 84137001N operates across 20–265VAC input range. For applications requiring operation below 90VAC input, the CWA2410H is the appropriate selection. For applications operating within the 90–265VAC window, both parts are functionally equivalent. All other electrical and mechanical parameters are identical, ensuring direct substitution capability within the specified input voltage overlap range.

Frequently Asked Questions (FAQ)

Q: Can the 84137001N replace the CWA2410H in all applications?

A: The 84137001N is functionally equivalent for applications where input voltage remains within the 90–265VAC range. Applications requiring input voltage operation below 90VAC or above 265VAC require the CWA2410H.

Q: Are the mechanical dimensions identical between these parts?

A: Both parts share identical mounting type (chassis mount) and package form factor (hockey puck), ensuring mechanical compatibility in existing installations.

Q: Do both parts support the same load voltage and current specifications?

A: Yes. Both parts are rated for 24–280V load voltage range and 10A load current, providing identical load-side performance.

Q: What is the significance of zero-cross output type?

A: Zero-cross detection ensures the relay switches at the AC voltage zero-crossing point, reducing electromagnetic interference and extending load component life in AC switching applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the CWA2410H and 84137001N carry RoHS compliance certification, meeting environmental and regulatory standards.

Q: Can these parts be used interchangeably in existing circuit designs?

A: Yes, provided the application input voltage falls within the 90–265VAC overlap range. Screw terminal connections and chassis mount configuration are identical, enabling direct mechanical and electrical substitution.
