CL240D05RC Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CL240D05RC is an active SPST-NO (1 Form A) solid state relay manufactured by Sensata-Crydom, designed for AC load switching applications. This hockey puck-style relay operates with a 3–32VDC input and handles loads from 24–280V at 5A maximum current. The component is RoHS3 compliant and features unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial control and switching applications requiring reliable solid-state performance.

Substitute parts become necessary when the original CL240D05RC is unavailable, when higher current capacity is required for the application, or when alternative sourcing is preferred while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CL240D05RC is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be AC to match load switching requirements
• Load Voltage Range: Must encompass or exceed the 24–280V specification
• Input Voltage Range: Must accommodate the 3–32VDC control signal
• Package / Case: Must be Hockey Puck form factor for mechanical compatibility
• Termination Style: Must be Screw Terminal for connection compatibility
• Mounting Type: Must be Chassis Mount for installation compatibility

The two identified substitute parts meet these core criteria while offering variations in load current capacity and input voltage minimums. Both maintain the same circuit topology, output type, load voltage range, package form factor, and termination method as the original CL240D05RC.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and compliance certifications required for industrial applications.

84137210N (Crouzet): This substitute provides a 5× increase in load current capacity (25A versus 5A) while maintaining the identical load voltage range (24–280V) and input voltage compatibility (4–32VDC minimum). The input voltage minimum increases from 3VDC to 4VDC, which is negligible for most control circuits. RoHS compliance is confirmed. This part is suitable when higher current switching capacity is required within the same voltage envelope.

ASR-SI240D10R-LRV (Altran Magnetics): This substitute provides a 2× increase in load current capacity (10A versus 5A) with a higher minimum load voltage specification (48V versus 24V). The input voltage range matches the Crouzet option (4–32VDC). RoHS3 compliance is confirmed. This part is suitable for applications where load voltage does not drop below 48V and moderate current increases are acceptable.

Selection between substitutes depends on application load voltage minimums and required current capacity. The Crouzet option supports the full 24V minimum load voltage of the original part. The Altran option requires minimum 48V load voltage but offers intermediate current capacity between the original and Crouzet options.

Frequently Asked Questions (FAQ)

Q: Can the 84137210N replace the CL240D05RC in all applications?

A: The 84137210N is mechanically and electrically compatible with the CL240D05RC for applications requiring up to 25A load current. The input voltage minimum increases from 3VDC to 4VDC, which does not affect standard control circuits. Both parts support the identical 24–280V load voltage range and hockey puck package form factor.

Q: What is the key difference between the two substitute parts?

A: The 84137210N (Crouzet) supports load voltages as low as 24V and provides 25A capacity. The ASR-SI240D10R-LRV (Altran Magnetics) requires minimum 48V load voltage but provides 10A capacity. Choose based on your application's minimum load voltage and required current rating.

Q: Are both substitutes RoHS compliant?

A: Yes. The 84137210N is RoHS compliant. The ASR-SI240D10R-LRV is RoHS3 compliant, matching the original CL240D05RC certification level.

Q: Will the substitutes fit in the same mounting location?

A: Yes. Both substitutes use the hockey puck package form factor with chassis mount configuration and screw terminal termination, identical to the CL240D05RC. Physical and electrical connection compatibility is maintained.

Q: Can I use the ASR-SI240D10R-LRV if my load voltage is 24V?

A: No. The ASR-SI240D10R-LRV specifies a minimum load voltage of 48V. For applications with 24V loads, use the CL240D05RC or the 84137210N (Crouzet), both of which support the full 24–280V load voltage range.

Q: What is the input voltage difference between the original and substitutes?

A: The CL240D05RC accepts input voltage from 3–32VDC. Both substitutes accept 4–32VDC. This 1VDC difference at the minimum is negligible for standard industrial control applications using 5V, 12V, or 24VDC control signals.
