CMRD2465 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CMRD2465 is a Solid State SPST-NO (1 Form A) relay manufactured by Sensata-Crydom, designed for AC load switching applications with zero-cross detection. This component integrates a heat sink for thermal management and operates with DC control inputs ranging from 3 to 32VDC, switching AC loads from 24V to 280V at up to 65A. The product is designated as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure continued availability and support for new designs or replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMRD2465 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must support AC switching with zero-cross detection for compatible control behavior
• Mounting Interface: Must support DIN Rail mounting for mechanical compatibility
• Termination: Must use Screw Terminal for electrical connection compatibility
• Package Form: Must include integrated heat sink for thermal management equivalence
• Control Input Range: Must accommodate 3 ~ 32VDC input specification
• Load Voltage Range: Must support minimum 24V operation; higher maximum ratings are acceptable
• Current Rating: Must support minimum 65A load current; higher ratings are acceptable

The DR4560D60 meets these substitution criteria with compatible electrical and mechanical specifications, though with enhanced load voltage range (48 ~ 600V) and slightly reduced current rating (60A).

Parameter Comparison

Engineering Selection Recommendations

The DR4560D60 is the designated manufacturer-recommended substitute for the CMRD2465. Both components are manufactured by Sensata Technologies entities and share identical circuit topology, output characteristics, and mechanical form factors.

Compatibility Assessment: The DR4560D60 maintains functional equivalence for applications operating within the CMRD2465 load voltage range (24 ~ 280V). The extended load voltage capability (up to 600V) of the DR4560D60 provides additional design flexibility without compromising performance in lower-voltage applications.

Current Rating Consideration: The DR4560D60 is rated for 60A maximum load current compared to the CMRD2465 at 65A. Applications requiring the full 65A capacity of the original part must be evaluated against the 60A limitation of the substitute.

Product Status: The CMRD2465 is Last Time Buy, indicating production discontinuation. The DR4560D60 maintains Active product status, ensuring long-term availability and continued manufacturer support.

Compliance: Both components meet applicable RoHS requirements. The DR4560D60 carries RoHS Compliant status, while the CMRD2465 is ROHS3 Compliant. Both are subject to REACH regulations and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the DR4560D60 directly replace the CMRD2465 in all applications?

A: The DR4560D60 is functionally equivalent for applications within its specified parameters. The primary consideration is load current: if your application requires the full 65A capacity of the CMRD2465, the 60A rating of the DR4560D60 may not be suitable. For applications operating at or below 60A, the substitute is compatible.

Q: What is the difference in load voltage range between these parts?

A: The CMRD2465 operates with load voltages from 24V to 280V. The DR4560D60 extends this range to 48V to 600V. Both parts function correctly within the CMRD2465 voltage window, so this difference does not restrict substitution for existing designs.

Q: Are the control input voltage ranges compatible?

A: The CMRD2465 accepts 3 ~ 32VDC control input, while the DR4560D60 accepts 4 ~ 32VDC. Applications using control voltages below 4VDC are not compatible with the DR4560D60 substitute.

Q: Do both parts use the same mounting and termination methods?

A: Yes. Both the CMRD2465 and DR4560D60 mount on DIN Rail and use Screw Terminal connections, ensuring mechanical and electrical interface compatibility.

Q: What is the significance of the Last Time Buy status for the CMRD2465?

A: Last Time Buy indicates that the manufacturer has discontinued production of the CMRD2465. This status necessitates transition to an equivalent part for new designs or future procurement. The DR4560D60 is the recommended active alternative.

Q: Are there any RoHS or regulatory differences between these parts?

A: Both parts comply with RoHS requirements and are subject to REACH regulations. The CMRD2465 is specifically ROHS3 Compliant, while the DR4560D60 is RoHS Compliant. Both are classified under ECCN EAR99 for export control purposes.
