Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA4890-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Load Current Rating: Must be rated for 90 A minimum to support the same load capacity
• Package / Case: Must be Hockey Puck format to ensure mechanical compatibility with existing mounting infrastructure
• Termination Style: Must use Screw Terminal connections for direct integration with existing wiring harnesses
• Mounting Type: Must be Chassis Mount to fit the same installation footprint
• Output Type: Must support AC output; zero-cross capability is permissible as an enhancement
• Input Voltage Range: Must accommodate the control signal voltage requirements of the application
• Load Voltage Range: Must encompass the operating voltage of the load circuit
• Product Status: Must be Active to ensure ongoing availability and support
• RoHS Compliance: Must maintain RoHS Compliant status for regulatory consistency

The substitute part 84138153N meets all mandatory substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4890-10 and 84138153N are active products with RoHS Compliant status, ensuring regulatory alignment and long-term supply availability. Selection between these parts depends on application-specific voltage requirements:

• CWA4890-10 is the primary choice for applications requiring load voltage operation up to 660 V, as the 84138153N is limited to 500 V maximum load voltage.
• 84138153N is suitable for applications where load voltage does not exceed 500 V and where input voltage may fall below 90 VAC, as this substitute supports input voltage as low as 20 VAC/DC.
• Both parts maintain identical load current capacity (90 A), circuit configuration (SPST-NO), and mechanical form factor (hockey puck with screw terminals), ensuring direct functional equivalence within their respective voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 84138153N replace the CWA4890-10 in all applications?

A: The 84138153N is functionally equivalent within overlapping voltage ranges. However, if your application requires load voltage operation above 500 V, the CWA4890-10 must be used, as the 84138153N maximum load voltage is 500 V. Verify your load voltage requirement before substitution.

Q: What is the difference between AC and AC with Zero Cross output?

A: Both output types support AC switching. The zero-cross feature in the 84138153N provides additional functionality by synchronizing relay switching to the AC voltage zero-crossing point, reducing electromagnetic interference. This is a compatible enhancement and does not prevent substitution.

Q: Are the physical dimensions and mounting footprints identical?

A: Both parts use the hockey puck package format with chassis mount configuration and screw terminal termination. Mechanical compatibility is confirmed for direct replacement in existing installations.

Q: Do both parts meet the same regulatory requirements?

A: Both the CWA4890-10 and 84138153N are RoHS Compliant and carry ECCN EAR99 classification. Regulatory compliance is equivalent for both parts.

Q: What input voltage range should I verify before substitution?

A: The CWA4890-10 requires input voltage between 90 ~ 280 VAC. The 84138153N accepts 20 ~ 260 VAC/DC. If your control signal voltage is below 90 VAC, only the 84138153N is suitable. If your control signal exceeds 260 VAC, only the CWA4890-10 is suitable.
