CMRA2435 Equivalent & Substitute Parts

Part Overview

The CMRA2435 is a Solid State Relay (SSR) with SPST-NO (1 Form A) configuration, manufactured by Sensata-Crydom. This component features an integrated heat sink, DIN Rail mounting, and screw terminal connections. It is rated for 35A load current with an input voltage range of 90–140VAC and a load voltage range of 24–280V. The CMRA2435 operates with AC output and zero-cross switching characteristics.

The CMRA2435 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMRA2435 is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Load Current Capacity: Minimum 35A rating required
• Load Voltage Range: Must encompass or exceed 24–280V specification
• Input Voltage Compatibility: Must accept 90–140VAC or broader input range
• Output Switching Type: AC output with zero-cross operation required
• Mounting and Termination: DIN Rail mounting with screw terminals required
• Package Form: Integrated heat sink configuration required

Two substitute parts meet these criteria:

1. DR2260A35U (Sensata-Crydom): Maintains identical load current (35A), circuit configuration, and mounting type. Extends load voltage range to 48–600V and input voltage range to 90–280VAC/DC. Remains within the same manufacturer family.

2. ASR-SV240A40ZY-L (Altran Magnetics, LLC): Provides 40A load current capacity (exceeds 35A requirement), maintains SPST-NO configuration, and preserves load voltage range (24–280V) and input voltage range (90–280VAC). Package form is Module rather than integrated heat sink.

Parameter Comparison

Engineering Selection Recommendations

DR2260A35U is the primary substitute for the CMRA2435. Both components are manufactured by Sensata-Crydom, share identical load current ratings and circuit configurations, and maintain the same mounting and termination standards. The DR2260A35U is classified as Active, ensuring continued availability and support. It extends the input voltage range to 90–280VAC/DC and the load voltage range to 48–600V, providing enhanced operational flexibility. Both components are RoHS Compliant.

ASR-SV240A40ZY-L serves as an alternative substitute when higher load current capacity is required or when module-based packaging is acceptable. This component is manufactured by Altran Magnetics, LLC and is classified as Active. It provides 40A load current capacity, exceeding the original 35A specification, and maintains the original load voltage range of 24–280V. The ASR-SV240A40ZY-L is ROHS3 Compliant, representing a more recent compliance standard. The primary distinction is the Module package type rather than integrated heat sink configuration.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A35U directly replace the CMRA2435 in all applications?

A: The DR2260A35U meets all critical substitution parameters: identical load current (35A), circuit configuration (SPST-NO), mounting type (DIN Rail), and termination style (screw terminal). The extended input and load voltage ranges do not create incompatibility. Direct replacement is supported.

Q: What is the primary difference between the DR2260A35U and ASR-SV240A40ZY-L?

A: The DR2260A35U maintains the integrated heat sink package and identical current rating (35A). The ASR-SV240A40ZY-L uses a Module package and provides higher current capacity (40A). Load voltage ranges differ: DR2260A35U extends to 600V, while ASR-SV240A40ZY-L maintains the original 24–280V range.

Q: Does the ASR-SV240A40ZY-L package type (Module vs. integrated heat sink) affect compatibility?

A: Package type affects physical installation and thermal management characteristics. Both configurations maintain DIN Rail mounting and screw terminal termination. Thermal design considerations specific to the application environment determine whether the Module package is suitable.

Q: Are both substitute parts RoHS compliant?

A: Yes. The DR2260A35U is RoHS Compliant. The ASR-SV240A40ZY-L is ROHS3 Compliant, representing a more recent regulatory standard. Both meet RoHS requirements.

Q: Why is the CMRA2435 classified as obsolete?

A: The CMRA2435 is no longer in active production. The DR2260A35U and ASR-SV240A40ZY-L are active alternatives that fulfill the same functional requirements.
