CWD4890-10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CWD4890-10 is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device in a Hockey Puck package. This relay is designed for AC load switching applications with input control voltage of 4–32VDC and output load voltage range of 48–660V at 90A capacity. The part is Active status and RoHS Compliant. Substitute parts may be required due to inventory constraints, series discontinuation, or application-specific performance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD4890-10 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC or AC with Zero Cross capability
• Input voltage range must support 4–32VDC control signal
• Load current rating must be equal to or greater than 90A
• Load voltage range must encompass or exceed 48–660V
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Package must be Hockey Puck form factor

Two substitute parts meet these criteria with variations in load current capacity and load voltage range.

Parameter Comparison

Engineering Selection Recommendations

84134340 (Sensata-Crydom GN Series)

This substitute maintains identical load voltage range (48–660V) and input voltage specification (4–32VDC) as the CWD4890-10. The load current rating is increased to 100A, providing additional capacity margin. Both parts are manufactured by Sensata-Crydom, ensuring consistent design philosophy and reliability standards. RoHS Compliance is maintained. This part is suitable for direct substitution in applications where the higher current rating does not create thermal or mechanical constraints.

84138150N (Crouzet GN+ Series)

This substitute maintains the 90A load current rating and 4–32VDC input voltage specification. The load voltage range is reduced to 24–500V, which does not encompass the full 48–660V range of the CWD4890-10. This part includes Zero Cross switching capability, which may provide benefits in noise reduction but is not present in the original specification. This part is suitable only for applications where the load voltage requirement does not exceed 500V. Cross-manufacturer substitution introduces different design and manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can 84134340 be used as a direct replacement for CWD4890-10?

A: Yes. The 84134340 maintains all critical electrical parameters: SPST-NO circuit, AC output, 4–32VDC input, 48–660V load voltage range, and Screw Terminal Hockey Puck package. The increased 100A current rating is compatible with applications designed for 90A operation.

Q: What is the primary limitation of 84138150N as a substitute?

A: The load voltage range of 84138150N is 24–500V, which does not cover the full 48–660V specification of CWD4890-10. Applications requiring load voltages above 500V cannot use this part. Additionally, 84138150N is manufactured by Crouzet rather than Sensata-Crydom.

Q: Are all three parts compatible with the same control circuit?

A: Yes. All three parts accept 4–32VDC input control voltage and use identical Screw Terminal connections. Control circuit compatibility is maintained across all substitutes.

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, ensuring mechanical compatibility in existing installations.

Q: What compliance certifications are maintained across all parts?

A: All three parts are RoHS Compliant and carry ECCN EAR99 classification. Regulatory compliance is consistent across the CWD4890-10 and both substitute parts.
