CWD2490P Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CWD2490P is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a 1 Form A circuit configuration. This hockey puck-style relay is designed for AC load switching applications with zero-cross detection capability. The part is currently active in production status. Equivalent and substitute parts may be required due to inventory constraints, supply chain considerations, or application-specific voltage and current requirements within compatible electrical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the CWD2490P is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must support AC switching with zero-cross detection
• Load Current: Must be rated for 90 A minimum
• Mounting Type: Must be chassis mount with hockey puck form factor
• Termination: Must use screw terminal configuration
• Input Voltage Compatibility: Control voltage range must overlap with or exceed 3 ~ 32 VDC
• Load Voltage Range: Must accommodate the application's operating voltage within the relay's rated range
• Compliance: Must maintain RoHS compliance status for regulated applications

The substitute part 84138150N (Crouzet GN+ series) meets all critical substitution criteria. While it features an extended load voltage range (24 V ~ 500 V versus 24 V ~ 280 V) and slightly higher input voltage floor (4 ~ 32 VDC versus 3 ~ 32 VDC), these differences represent enhanced capability rather than incompatibility. The identical load current rating (90 A), circuit type, output characteristics, and physical form factor ensure functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD2490P and 84138150N are active production components with RoHS compliance certification, making either suitable for regulated applications. Selection between these parts should be based on the specific application requirements:

• CWD2490P is the primary choice when the application operates within the 24 V ~ 280 V load voltage range and requires input voltage as low as 3 VDC.
• 84138150N is suitable as a substitute when the application can tolerate a 4 VDC minimum input threshold and may benefit from the extended load voltage capability (up to 500 V).

Both parts maintain identical load current capacity (90 A), circuit topology, and physical form factor. The choice between manufacturers should consider supply availability, lead time, and any existing qualification requirements within the design or procurement framework.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N directly replace the CWD2490P in all applications?

A: The 84138150N is functionally equivalent for applications where the load voltage does not exceed 280 V and the control voltage is 4 VDC or higher. If the application requires control voltages below 4 VDC, the CWD2490P is the required choice.

Q: Are there any physical differences between these relays?

A: Both relays use the hockey puck form factor with chassis mount configuration and screw terminal termination. Physical dimensions and mounting footprints are compatible.

Q: Do both parts support the same switching frequency and zero-cross detection?

A: Yes. Both the CWD2490P and 84138150N feature AC output type with zero-cross detection, ensuring identical switching characteristics for AC load applications.

Q: What is the significance of the extended voltage range on the 84138150N?

A: The 84138150N's load voltage range extends to 500 V, compared to the CWD2490P's 280 V maximum. This provides additional design flexibility for applications requiring higher voltage switching, though both parts are rated for identical load current (90 A).

Q: Are both parts RoHS compliant?

A: Yes. Both the CWD2490P and 84138150N carry RoHS compliance certification, meeting regulatory requirements for restricted substance elimination.

Q: What packaging formats are available?

A: The CWD2490P is supplied in bulk packaging, while the 84138150N is supplied in box packaging. Both formats contain the same component specifications.
