Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA4850-10 is determined by strict alignment of the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must be AC
• Load current rating must be 50A
• Load voltage range must encompass 48V to 660V
• Package form factor must be Hockey Puck
• Termination style must be Screw Terminal
• Mounting type must be Chassis Mount

The substitute part 84137321N, manufactured by Crouzet, meets these core electrical and mechanical requirements. Minor variations in input voltage range (90 ~ 260VAC versus 90 ~ 280VAC) remain within acceptable substitution parameters as the substitute maintains compatibility with standard industrial control voltage supplies.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4850-10 and 84137321N maintain Active product status, ensuring continued manufacturer support and availability. The CWA4850-10 carries RoHS3 compliance certification, while the 84137321N is RoHS compliant. Both components are classified under ECCN EAR99 and share the same HTSUS code (8536.49.0080), indicating equivalent regulatory treatment for export and procurement purposes. Selection between these parts should be based on inventory availability, lead time requirements, and established supplier relationships, as both components satisfy the electrical and mechanical specifications for SPST-NO AC switching applications at 50A load current.

Frequently Asked Questions (FAQ)

Q: Can the 84137321N directly replace the CWA4850-10 in existing installations?

A: Yes. Both components share identical circuit configuration (SPST-NO), output type (AC), load current rating (50A), load voltage range (48V to 660V), package form factor (Hockey Puck), termination style (Screw Terminal), and mounting type (Chassis Mount). The input voltage range difference (90 ~ 260VAC versus 90 ~ 280VAC) does not prevent substitution in standard industrial control applications.

Q: What is the significance of the Hockey Puck package form factor?

A: The Hockey Puck package is a standardized form factor for high-current solid state relays designed for chassis mount applications. This form factor ensures mechanical compatibility with existing mounting infrastructure and thermal management systems. Both the CWA4850-10 and 84137321N utilize this identical package, guaranteeing mechanical interchangeability.

Q: Are there compliance differences between the two parts?

A: The CWA4850-10 is RoHS3 compliant, while the 84137321N is RoHS compliant. Both are REACH Compliant or REACH Unaffected respectively, and both carry EAR99 classification. These certifications indicate suitability for current regulatory environments. Specific compliance requirements should be verified against application-specific standards.

Q: What determines whether a part qualifies as a substitute?

A: Substitution eligibility is strictly determined by matching circuit configuration, output type, load current rating, load voltage range, package form factor, termination style, and mounting type. The CWA4850-10 and 84137321N meet all these criteria, establishing them as equivalent alternatives for SPST-NO AC switching applications.

Q: Does the screw terminal termination style affect installation procedures?

A: No. Both components utilize screw terminal connections, ensuring identical installation procedures and wiring practices. Screw terminals provide secure, field-serviceable connections suitable for industrial control panel applications.
