CSE2490 Solid State Relay SPST-NO 90A 24-280V Equivalent & Substitute Parts

Part Overview

The CSE2490 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device rated for 90A load current at 24-280V AC output. This component features a hockey puck form factor with screw terminal connections and zero-cross switching capability. The CSE2490 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the CSE2490 is determined by the following critical parameters:

Circuit Configuration: Must be SPST-NO (1 Form A)
Load Voltage Range: Must support 24 V – 280 V AC
Output Type: Must be AC with zero-cross switching
Termination Style: Must be screw terminal
Mounting Type: Must be chassis mount
Load Current Rating: Must meet or exceed 90 A

The three substitute parts listed below satisfy these core electrical and mechanical requirements. Variations in input voltage range, package form factor (hockey puck vs. module), and product status are secondary considerations that do not preclude substitution when load current capacity and voltage specifications are met.

Engineering Selection Recommendations

D24125 (Sensata-Crydom): This part provides the highest load current capacity at 125 A, exceeding the CSE2490 requirement of 90 A. It maintains identical load voltage range, output type, and package form factor. The part is active and ROHS3 compliant. The expanded input voltage range (3–32 VDC vs. 15–32 VDC) provides additional operational flexibility. REACH status indicates this part is subject to REACH regulations.

84134040 (Sensata-Crydom): This part delivers 100 A load current capacity, directly exceeding the 90 A requirement. It maintains all critical electrical specifications and package form factor. The part is active and RoHS compliant. The expanded input voltage range (3–32 VDC) offers operational margin. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints.

ASR-SN240D100ZW-L (Altran Magnetics, LLC): This part provides 100 A load current capacity and meets all electrical specifications. It is active and ROHS3 compliant with REACH unaffected status. The primary distinction is the module package form factor rather than hockey puck. The expanded input voltage range (3–32 VDC) provides operational margin.

Frequently Asked Questions (FAQ)

Q: Can the D24125 be used as a direct replacement for the CSE2490?

A: Yes. The D24125 meets all critical substitution parameters: SPST-NO circuit configuration, 24–280 V load voltage range, AC zero-cross output, screw terminal connections, and chassis mount configuration. The 125 A load current rating exceeds the 90 A requirement. The expanded input voltage range (3–32 VDC) is compatible with systems designed for the CSE2490's 15–32 VDC range.

Q: What is the difference between the hockey puck and module package forms?

A: Both package types are chassis mount configurations with screw terminal connections. The hockey puck form factor is a compact cylindrical design, while the module form factor is a rectangular enclosure. Both provide equivalent electrical performance and thermal management for the specified load ratings. Physical mounting dimensions may differ; verify mechanical fit in your application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CSE2490 is RoHS compliant. All three substitute parts are either RoHS compliant or ROHS3 compliant, meeting current regulatory requirements.

Q: Can I use a substitute part with a lower load current rating than 90 A?

A: No. The substitute part must have a load current rating equal to or greater than 90 A to ensure safe operation under the CSE2490's design specifications.

Q: What is the significance of the expanded input voltage range in the substitute parts?

A: The substitute parts accept input voltages from 3–32 VDC, compared to the CSE2490's 15–32 VDC range. This expanded range provides operational margin and compatibility with a broader range of control circuits. Systems designed for the CSE2490 will operate normally with substitute parts.

Q: Are there any REACH compliance considerations?

A: The D24125 is REACH affected. The 84134040 has no specified REACH status in the provided data. The ASR-SN240D100ZW-L is REACH unaffected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.
