CWU2490 Equivalent & Substitute Parts

Part Overview

The CWU2490 is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. 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 device features zero-cross switching capability and screw terminal connections for chassis mount installation. The CWU2490 maintains Active product status and is RoHS Compliant. Equivalent parts are identified when alternative SSR models meet the same functional and electrical requirements, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The CWU2490 has one identified equivalent part: the Crouzet 84138153N. Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: Both parts must be SPST-NO (1 Form A) topology
• Load Current Rating: Minimum 90 A capacity required
• Output Type: AC switching with zero-cross capability
• Package Form Factor: Hockey puck configuration for mechanical compatibility
• Termination: Screw terminal connection standard
• Mounting: Chassis mount orientation
• Compliance: RoHS Compliant status

The Crouzet 84138153N meets all substitution criteria. While it offers an extended load voltage range (24 V ~ 500 V versus 24 V ~ 280 V), this represents a superset of the CWU2490 operating envelope and does not restrict compatibility in applications designed for the CWU2490.

Parameter Comparison

Engineering Selection Recommendations

Both the CWU2490 and 84138153N are Active products with RoHS Compliant certification, meeting current regulatory requirements. The Crouzet 84138153N provides equivalent functionality with identical load current capacity and circuit topology. The extended load voltage specification of the 84138153N (500 V maximum versus 280 V) does not introduce incompatibility; applications designed for the CWU2490 operate within the Crouzet part's rated envelope. Selection between these parts may be based on availability, lead time, packaging preference (Bulk versus Box), or supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N replace the CWU2490 in existing applications?

A: Yes. Both parts share identical SPST-NO circuit topology, 90 A load current rating, AC zero-cross output type, hockey puck package form factor, screw terminal connections, and chassis mount configuration. The Crouzet part's higher voltage rating (500 V) is a superset of the CWU2490 specification and does not restrict compatibility.

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

A: The CWU2490 accepts 20 ~ 280VAC or 20 ~ 48VDC input. The 84138153N accepts 20 ~ 260VAC/DC input. Both specifications overlap in the 20 ~ 260V range, ensuring compatibility for standard control voltage applications.

Q: Are there packaging differences between these parts?

A: The CWU2490 is supplied in Bulk packaging, while the 84138153N is supplied in Box packaging. Both use identical hockey puck form factors and screw terminal connections. Packaging selection depends on procurement and inventory management requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CWU2490 and 84138153N are RoHS Compliant and carry Active product status, meeting current regulatory and supply continuity requirements.

Q: What determines whether a part can substitute for the CWU2490?

A: Substitution requires matching circuit type (SPST-NO), load current rating (90 A minimum), output type (AC, zero-cross), package form factor (hockey puck), termination style (screw terminal), and mounting configuration (chassis mount). Load voltage and input voltage specifications must not fall below the CWU2490 requirements.
