CMRA6035 Equivalent & Substitute Parts

Part Overview

The CMRA6035 is a Solid State SPST-NO (1 Form A) relay manufactured by Sensata-Crydom, designed for AC load switching applications with integrated heat sink and DIN Rail mounting. This component operates with input voltage range of 90–140VAC and supports load voltages from 48V to 660V at 35A capacity with zero-cross switching capability.

The CMRA6035 is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMRA6035 are identified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 35A capacity
• Output Type: AC switching with zero-cross detection
• Mounting Interface: DIN Rail compatibility
• Termination Method: Screw Terminal connection
• Package Form: SSR with Integrated Heat Sink
• Compliance: RoHS Compliant status

The DR2260A35U qualifies as a substitute based on matching these core parameters. While input voltage range and maximum load voltage differ, the substitute maintains functional compatibility for applications within the overlapping voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The DR2260A35U is an active product from Sensata-Crydom and serves as the recommended substitute for the CMRA6035. Both components are RoHS Compliant and maintain identical circuit topology, current rating, and mechanical form factor.

The DR2260A35U offers extended input voltage capability (90–280VAC/DC versus 90–140VAC) and broader input flexibility. The maximum load voltage specification of the DR2260A35U is 600V compared to 660V for the CMRA6035; applications requiring operation above 600V load voltage must retain the CMRA6035 or identify alternative solutions.

Selection of the DR2260A35U is appropriate for new designs and production applications where the load voltage requirement does not exceed 600V and input voltage falls within the 90–280VAC/DC range.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A35U directly replace the CMRA6035 in existing applications?

A: Direct replacement is possible when the application load voltage does not exceed 600V. The DR2260A35U maintains identical circuit configuration, current rating, DIN Rail mounting, and screw terminal termination. Verify that your application load voltage specification is within the 48V–600V range supported by the substitute.

Q: What is the primary difference between these two parts?

A: The CMRA6035 supports load voltages up to 660V with input voltage range of 90–140VAC. The DR2260A35U supports load voltages up to 600V but offers broader input voltage flexibility (90–280VAC/DC). Both parts are electrically and mechanically equivalent for applications within the overlapping voltage specifications.

Q: Why is the CMRA6035 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The DR2260A35U from the active DR22 series is the recommended path forward for continued component availability.

Q: Are both parts RoHS Compliant?

A: Yes, both the CMRA6035 and DR2260A35U are RoHS Compliant and suitable for applications requiring environmental compliance.

Q: What mounting and termination options are available?

A: Both parts feature DIN Rail mounting and screw terminal termination, ensuring mechanical and electrical interface compatibility in standard industrial control panel installations.
