CWD2490-10 Equivalent & Substitute Parts

Part Overview

The CWD2490-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) in a hockey puck package. This component is designed for AC load switching applications with a rated load current of 90A and operates across a load voltage range of 24V to 280V. The part is currently in active production status and is RoHS compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category. The CWD2490-10 has one qualified substitute in the Crouzet GN+ series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD2490-10 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Load current rating must be rated for 90 A minimum
• Load voltage range must encompass or exceed 24 V ~ 280 V
• Input voltage range must be compatible with 3 ~ 32 VDC control signals
• Package type must be hockey puck with screw terminal termination
• Mounting configuration must support chassis mount installation
• RoHS compliance status must be maintained

The Crouzet 84138150N meets all substitution criteria. While it offers an extended load voltage range (24 V ~ 500 V) and includes zero-cross switching capability, these represent enhanced specifications that do not compromise compatibility with applications designed for the CWD2490-10.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD2490-10 and 84138150N are active production components with RoHS compliance certification. Selection between these parts should be based on application-specific requirements:

The CWD2490-10 is the primary specification for existing designs and applications validated against Sensata-Crydom CW24 series parameters.

The 84138150N serves as a qualified substitute when supply constraints affect CWD2490-10 availability. The extended load voltage range (500V maximum versus 280V) and zero-cross switching feature provide operational flexibility for applications operating within the CWD2490-10 load voltage envelope. The minimum input voltage specification of 4VDC (versus 3VDC) represents a minor operational constraint that does not affect standard 24VDC control signal applications.

Both components maintain identical load current ratings, circuit configurations, and mechanical form factors, ensuring direct functional equivalence within specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138150N be used as a direct replacement for the CWD2490-10?

A: Yes. Both components share identical circuit configuration (SPST-NO), load current rating (90A), package type (hockey puck), and termination style (screw terminal). The 84138150N's extended load voltage range and zero-cross switching do not create incompatibility with CWD2490-10 applications.

Q: What is the difference in input voltage specifications between these parts?

A: The CWD2490-10 accepts input signals from 3VDC to 32VDC, while the 84138150N operates from 4VDC to 32VDC. For standard 24VDC control circuits, this difference is not operationally significant.

Q: Does the zero-cross switching feature on the 84138150N affect compatibility?

A: No. Zero-cross switching is an additional feature that enhances EMI performance and reduces switching transients. It does not compromise compatibility with applications designed for standard AC output switching.

Q: Are both parts suitable for the same load voltage applications?

A: The CWD2490-10 is rated for 24V to 280V loads. The 84138150N extends this range to 500V. Applications operating within the 24V to 280V envelope are fully compatible with either component.

Q: What packaging formats are available for these parts?

A: The CWD2490-10 is supplied in bulk packaging. The 84138150N is supplied in box packaging. Both maintain identical hockey puck form factors and screw terminal configurations.
