CL240A05C Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CL240A05C is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration with a 5A load current rating. This hockey puck-style relay operates across 24V to 280V load voltage range with zero-cross AC output switching. The component is RoHS compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial control applications requiring reliable AC switching without mechanical contacts.

Substitute parts become necessary when inventory constraints exist, when higher current ratings are required for application scaling, or when alternative manufacturer certifications align with supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CL240A05C is determined by the following critical parameters:

• Circuit Configuration: Must maintain SPST-NO (1 Form A) topology for direct functional replacement
• Output Switching Type: Must support AC with zero-cross capability to preserve load protection characteristics
• Load Voltage Compatibility: Substitute must cover the 24V to 280V range or encompass the application's specific voltage requirement
• Mounting and Termination: Hockey puck package with screw terminal configuration ensures mechanical and electrical interface compatibility
• Current Rating: Substitutes with equal or higher current ratings (5A minimum) maintain or exceed performance capability

The two identified substitutes meet these criteria with the following distinctions:

84137001N (Crouzet): Provides 10A current capacity with identical load voltage range (24V ~ 280V) and input voltage specification (20 ~ 265VAC). Maintains SPST-NO configuration, AC zero-cross output, hockey puck package, and screw terminal termination.

ASR-SI240A10ZY-LV (Altran Magnetics): Provides 10A current capacity with expanded input voltage range (90 ~ 280VAC) and elevated minimum load voltage (48V ~ 280V). Maintains SPST-NO configuration, AC zero-cross output, hockey puck package, and screw terminal termination.

Parameter Comparison

Engineering Selection Recommendations

CL240A05C (Primary Specification): Select when 5A load current capacity meets application requirements and Sensata-Crydom supply chain preference is established. RoHS compliance and active product status support long-term availability.

84137001N (Crouzet Alternative): Select when higher current capacity (10A) is required and input voltage range of 20 ~ 265VAC aligns with system specifications. Maintains identical load voltage coverage (24V ~ 280V) and RoHS compliance. Suitable for applications requiring current margin above 5A threshold.

ASR-SI240A10ZY-LV (Altran Magnetics Alternative): Select when 10A current capacity is required and input voltage extends to 280VAC. Note that minimum load voltage is 48V; this substitute is not suitable for applications requiring 24V to 47V load operation. ROHS3 compliance provides enhanced environmental standards. Recommended by manufacturer for specific supply chain scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 84137001N directly replace the CL240A05C in all applications?

A: Direct replacement is possible when the application load current does not exceed 5A and input voltage remains within 20 ~ 265VAC range. The 10A rating provides current margin without functional penalty. Verify that the application does not require operation below 24V load voltage.

Q: What is the key limitation of the ASR-SI240A10ZY-LV substitute?

A: The minimum load voltage specification is 48V, compared to 24V for the CL240A05C. This substitute cannot be used in applications requiring 24V to 47V load operation. Confirm application load voltage requirements before selection.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical mounting type (chassis mount), termination style (screw terminal), and package configuration (hockey puck). Physical installation is interchangeable.

Q: Do input voltage ranges affect substitution suitability?

A: Input voltage range affects suitability based on control circuit specifications. The CL240A05C operates 90 ~ 250VAC. The 84137001N extends to 265VAC and accepts lower input (20VAC minimum). The ASR-SI240A10ZY-LV operates 90 ~ 280VAC. Confirm control voltage supply matches the selected part's input specification.

Q: What compliance differences exist between the substitutes?

A: CL240A05C and 84137001N are RoHS compliant. ASR-SI240A10ZY-LV is ROHS3 compliant, representing enhanced environmental standards. Both certifications are acceptable for industrial applications; ROHS3 provides additional regulatory alignment for certain markets.

Q: Can the 5A-rated CL240A05C be replaced with a 10A-rated substitute in a 5A application?

A: Yes. Higher current-rated components operate safely at lower current levels. The 10A substitutes provide performance margin and thermal headroom in 5A applications without functional compromise.
