CWU2490-10 Equivalent & Substitute Parts

Part Overview

The CWU2490-10 is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a rated load current of 90 A and operates across a voltage range of 24 V to 280 V. The part is currently active in production and RoHS compliant, making it suitable for modern industrial control and power switching applications where mechanical relay alternatives are no longer preferred.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for alternative manufacturers meeting the same functional and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWU2490-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current Rating: Must be rated for 90 A minimum to handle the same load
• Load Voltage Range: Must support the 24 V to 280 V operating window
• Package Type: Must be hockey puck form factor for mechanical compatibility
• Mounting Type: Must be chassis mount to fit existing mechanical installations
• Termination: Must use screw terminal connections for direct wiring compatibility
• Compliance: Must maintain RoHS compliance for regulatory alignment

The substitute part 84138153N (Crouzet GN+ series) meets all mandatory substitution criteria. While this part offers an extended load voltage range (24 V to 500 V) and includes zero-cross switching capability, these represent functional enhancements rather than deviations from the core specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CWU2490-10 and 84138153N are active production components with RoHS compliance certification, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on supply availability and lead time requirements rather than functional differences.

The CWU2490-10 (Sensata Technologies) is the primary specification. The 84138153N (Crouzet) serves as a qualified substitute when the primary part is unavailable. The Crouzet part's extended load voltage range (500 V maximum versus 280 V) and zero-cross switching feature provide additional operational margin in applications where these characteristics are beneficial, though they are not required for direct substitution.

Both parts maintain identical load current capacity (90 A), circuit configuration (SPST-NO), mechanical form factor (hockey puck), and termination method (screw terminal), ensuring drop-in compatibility within the specified application envelope.

Frequently Asked Questions (FAQ)

Q: Can the 84138153N (Crouzet) be used as a direct replacement for the CWU2490-10 (Sensata)?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current rating (90 A), package type (hockey puck), mounting method (chassis mount), and termination style (screw terminal). The Crouzet part's extended voltage range and zero-cross capability do not prevent substitution within the CWU2490-10 specification envelope.

Q: What is the difference between the input voltage specifications?

A: The CWU2490-10 accepts 20 ~ 280VAC or 20 ~ 48VDC input. The 84138153N accepts 20 ~ 260VAC/DC input. Both specifications overlap sufficiently for standard industrial control applications operating at 24 VDC or 120/240 VAC control voltages.

Q: Does the zero-cross switching feature on the Crouzet part affect compatibility?

A: No. Zero-cross switching is a functional enhancement that reduces electromagnetic interference and switching transients. It does not alter the basic SPST-NO switching behavior required by the CWU2490-10 specification.

Q: Are both parts suitable for the same mechanical installation?

A: Yes. Both parts use identical hockey puck packaging, chassis mount configuration, and screw terminal termination, allowing direct mechanical and electrical substitution without modification to the mounting structure or wiring harness.

Q: What compliance certifications apply to both parts?

A: Both the CWU2490-10 and 84138153N are RoHS compliant, meeting current environmental and regulatory requirements for industrial component applications.
