Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA4890P is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) topology
• Output Characteristics: Must support AC switching with zero-cross detection
• Load Voltage Compatibility: Must accommodate the 48 V ~ 660 V range
• Current Rating: Must meet or exceed 90 A load current capability
• Mechanical Form Factor: Must be Hockey Puck package with Chassis Mount configuration
• Termination Interface: Must use Screw Terminal connection
• Regulatory Compliance: Must maintain RoHS Compliant status

The substitute part 84137141N (Crouzet, GN Series) meets these criteria with a 100 A load current rating, which exceeds the 90 A requirement of the main part, while maintaining identical circuit topology, output type, load voltage range, package form factor, and termination style.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4890P and 84137141N are Active products with current manufacturing status and full RoHS compliance. The 84137141N substitute provides equivalent functionality with a higher load current rating (100 A versus 90 A), which does not create incompatibility in applications designed for the 90 A specification. The input voltage range of the 84137141N (20 ~ 265 VAC) overlaps with the CWA4890P range (90 ~ 280 VAC) across the 90 ~ 265 VAC band, ensuring compatibility in standard industrial control applications. Both parts maintain identical circuit topology, output switching characteristics, load voltage capability, mechanical form factor, and termination interface. Selection between these parts may be based on availability, lead time, or specific application input voltage requirements outside the 90 ~ 265 VAC overlap range.

Frequently Asked Questions (FAQ)

Q: Can the 84137141N be used as a direct replacement for the CWA4890P?

A: Yes, within the overlapping input voltage range of 90 ~ 265 VAC. Both parts are SPST-NO Hockey Puck relays with identical load voltage ranges (48 V ~ 660 V), screw terminal connections, and zero-cross AC switching capability. The 84137141N's 100 A current rating exceeds the CWA4890P's 90 A specification, maintaining compatibility for applications designed around the lower current requirement.

Q: What is the input voltage compatibility between these two parts?

A: The CWA4890P operates at 90 ~ 280 VAC input, while the 84137141N operates at 20 ~ 265 VAC input. The common operating range is 90 ~ 265 VAC. Applications requiring input voltages between 265 ~ 280 VAC must use the CWA4890P. Applications operating below 90 VAC input must use the 84137141N.

Q: Are the mechanical packages identical?

A: Yes. Both parts use the Hockey Puck package form factor with Chassis Mount configuration and Screw Terminal termination style, ensuring identical mechanical fit and installation requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the CWA4890P and 84137141N are RoHS Compliant and carry Active product status, indicating current manufacturing support and compliance with applicable environmental regulations.

Q: What determines whether a part can substitute for the CWA4890P?

A: Substitution requires matching circuit topology (SPST-NO), output type (AC with zero-cross detection), load voltage range (48 V ~ 660 V), package form factor (Hockey Puck), termination style (Screw Terminal), and load current capability equal to or exceeding 90 A. Input voltage range must overlap with the application requirement.
