CL240A10R Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CL240A10R is an active, RoHS-compliant solid state relay (SSR) manufactured by Sensata-Crydom. This SPST-NO (1 Form A) relay is designed for AC load switching applications with a rated load current of 10A and load voltage range of 24V to 280V. The hockey puck form factor with screw terminal connections provides chassis-mount installation for industrial control systems.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design requirements permit operation within expanded electrical parameters while maintaining the same functional circuit topology and mechanical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CL240A10R is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit topology: SPST-NO (1 Form A) configuration
• Output type: AC switching
• Mechanical form factor: Hockey puck package
• Termination: Screw terminal connections
• Mounting: Chassis mount capability
• Load voltage range: Minimum 24V to 280V coverage

Allowable Parameter Variations:

• Input voltage range may exceed the original specification (higher input voltage tolerance is acceptable)
• Load current rating may exceed 10A (higher current capacity provides design margin)
• Manufacturer origin (different qualified suppliers)
• RoHS compliance status (RoHS3 acceptable for RoHS-compliant applications)

The two identified substitute parts meet these criteria while maintaining functional and mechanical compatibility with the CL240A10R.

Parameter Comparison

Engineering Selection Recommendations

84137211N (Crouzet): This substitute provides identical load voltage range coverage (24V to 280V) with expanded input voltage tolerance (90 ~ 260VAC versus 90 ~ 250VAC). The 25A load current rating exceeds the CL240A10R specification, providing additional design margin for applications requiring 10A switching. RoHS compliance and active product status confirm ongoing manufacturer support. Selection is appropriate for applications where higher current capacity is beneficial or neutral.

ASR-SI240A10RY-L (Altran Magnetics): This substitute matches the 10A load current rating and provides the widest input voltage range (90 ~ 280VAC). The load voltage range begins at 48V rather than 24V, restricting use to applications where the minimum load voltage is 48V or higher. ROHS3 compliance and active product status are confirmed. Selection requires verification that the 48V minimum load voltage does not conflict with application requirements.

All three parts maintain identical circuit topology, output type, mechanical form factor, and termination style, ensuring direct functional substitution within their respective electrical parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 84137211N (25A rating) be used in place of the CL240A10R (10A rating)?

A: Yes. The 84137211N provides a higher current capacity while maintaining identical load voltage range (24V to 280V) and input voltage compatibility (90 ~ 260VAC). Higher current rating does not prevent operation at lower currents. The hockey puck form factor and screw terminal connections are identical.

Q: What is the key limitation of the ASR-SI240A10RY-L substitute?

A: The ASR-SI240A10RY-L specifies a minimum load voltage of 48V, compared to 24V for the CL240A10R. This substitute is not suitable for applications requiring load switching below 48V. Verify application load voltage requirements before selection.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share the hockey puck package form factor, chassis mount configuration, and screw terminal termination style. Physical installation and electrical connection methods are identical.

Q: Do compliance certifications differ between the three parts?

A: The CL240A10R and 84137211N are RoHS Compliant. The ASR-SI240A10RY-L is ROHS3 Compliant. Both compliance levels are acceptable for RoHS-regulated applications. All three parts are REACH Unaffected or not subject to REACH restrictions.

Q: What input voltage range is supported across all three parts?

A: The CL240A10R supports 90 ~ 250VAC. The 84137211N extends this to 90 ~ 260VAC. The ASR-SI240A10RY-L provides the widest range at 90 ~ 280VAC. All three accommodate standard industrial AC supply voltages.

Q: Can these parts be used interchangeably in existing designs?

A: Functional interchangeability is confirmed for circuit topology, output type, and mechanical installation. Electrical parameter verification is required: confirm that application load voltage and current requirements fall within the substitute part's specification. The ASR-SI240A10RY-L requires specific attention to the 48V minimum load voltage threshold.
