CMRD4835P Equivalent & Substitute Parts

Part Overview

The CMRD4835P is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) relay with integrated heat sink for DIN Rail mounting. This component operates with a 4–32VDC input and controls AC loads from 48V to 530V at 35A with zero-cross switching. The CMRD4835P is designated as Last Time Buy, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new system designs requiring compatible SSR functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMRD4835P is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must be AC with zero-cross switching
• Input voltage range must accommodate 4–32VDC
• Load current rating must be at least 35A
• Load voltage range must encompass or exceed 48V–530V
• Mounting type must support DIN Rail installation
• Termination style must be Screw Terminal
• Package must include integrated heat sink or equivalent thermal management

The two substitute parts listed meet these criteria with the following considerations:

DR2260D35U (Sensata-Crydom): Maintains identical input voltage, load current, circuit configuration, and mounting specifications. Load voltage range extends to 600V, exceeding the original specification. Product status is Active, ensuring continued availability.

GNR45DCZP (Crouzet): Maintains identical input voltage, circuit configuration, and mounting flexibility (supports both Chassis Mount and DIN Rail). Load current is rated at 32A, which is 3A below the original 35A specification. Load voltage range is 24V–500V, with the lower bound below the original 48V minimum. This part represents a functional alternative for applications with reduced current requirements.

Parameter Comparison

Engineering Selection Recommendations

DR2260D35U is the primary substitute for direct replacement applications. This part is manufactured by the same supplier (Sensata-Crydom), maintains identical electrical specifications for input voltage and load current, and extends the load voltage capability to 600V. The part holds Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance exceeds the original RoHS requirement. This substitution requires no circuit redesign or thermal management modifications.

GNR45DCZP is suitable for applications where load current requirements do not exceed 32A and load voltage remains within the 24V–500V range. This part is manufactured by Crouzet and holds Active product status. The lower current rating and reduced upper voltage limit require verification against specific application requirements before selection. This part offers mounting flexibility with both Chassis Mount and DIN Rail options.

Frequently Asked Questions (FAQ)

Q: Can DR2260D35U be used as a direct drop-in replacement for CMRD4835P?

A: Yes. DR2260D35U maintains identical input voltage (4–32VDC), load current (35A), circuit configuration (SPST-NO), output type (AC, zero-cross), mounting type (DIN Rail), and termination style (Screw Terminal). The extended load voltage range (48V–600V) is compatible with applications designed for the original 48V–530V specification.

Q: What are the limitations of GNR45DCZP as a substitute?

A: GNR45DCZP has a load current rating of 32A, which is 3A below the CMRD4835P specification of 35A. The load voltage range is 24V–500V, with the upper limit 30V below the original 530V maximum. These differences require application-specific verification to confirm compatibility.

Q: Are there thermal management differences between the substitutes?

A: CMRD4835P and DR2260D35U both feature integrated heat sinks. GNR45DCZP is packaged as a Module. Thermal performance characteristics are determined by the integrated heat sink design and must be evaluated against specific application duty cycles and ambient temperature conditions.

Q: Do the substitute parts have different compliance certifications?

A: DR2260D35U carries ROHS3 compliance, which exceeds the RoHS compliance of CMRD4835P. GNR45DCZP carries RoHS compliance equivalent to the original part. Both substitutes carry the same ECCN (EAR99) and HTSUS (8536.49.0080) classifications as the original part.

Q: What is the inventory status of the substitute parts?

A: DR2260D35U has 843 pieces in stock. GNR45DCZP has 683 pieces in stock. Both parts are available as new original components.
