CKRB2430P Solid State Relay SPST-NO 30A Equivalent & Substitute Parts

Part Overview

The CKRB2430P is a Solid State SPST-NO (1 Form A) relay manufactured by Sensata-Crydom, designed for applications requiring 30A switching capacity with integrated heat sink. This component operates across a 24-280V input range and is suitable for AC load switching with zero-cross detection. Finding equivalent and substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific application requirements across different mounting configurations and load voltage ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CKRB2430P is determined by strict alignment of the following electrical and mechanical parameters:

• Load Current Rating: All substitutes must maintain 30A switching capacity
• Circuit Configuration: SPST-NO (1 Form A) topology is mandatory
• Output Type: AC switching with zero-cross detection capability
• Termination: Screw terminal connection required
• Heat Management: Integrated heat sink or equivalent thermal design
• Compliance: RoHS compliance status

The substitute parts identified—DR2260A30U and GNR30BCZH—meet these core requirements while accommodating variations in input voltage ranges and load voltage specifications. These substitutes are interchangeable within applications where the input and load voltage parameters fall within the overlapping operational ranges.

Parameter Comparison

Engineering Selection Recommendations

DR2260A30U (Sensata-Crydom, DR22 Series): This substitute maintains manufacturer continuity with Sensata-Crydom and provides expanded load voltage capability (48-600V). The input voltage range (90-280VAC/DC) overlaps with the CKRB2430P within the 90-280V band. DIN Rail mounting is specified. Product status is Active with RoHS compliance confirmed. This option is suitable for applications where the input voltage remains above 90V and load voltage requirements extend to 600V.

GNR30BCZH (Crouzet, GNR Series): This substitute introduces a different manufacturer (Crouzet) with a module-based package design supporting both Chassis Mount and DIN Rail configurations. The input voltage range (80-140VAC) is narrower than the CKRB2430P, limiting applicability to lower input voltage systems. Load voltage capability extends to 660V. Product status is Active with RoHS compliance and REACH Unaffected status confirmed. This option is appropriate for applications with input voltages between 80-140VAC and requiring modular mounting flexibility.

Frequently Asked Questions (FAQ)

Q: Can DR2260A30U replace CKRB2430P in all applications?

A: DR2260A30U is compatible when the application input voltage is 90V or higher. Applications requiring input voltages below 90V cannot use this substitute. Both parts maintain 30A load current, SPST-NO circuit configuration, AC zero-cross output, and screw terminal termination.

Q: What are the mounting differences between these substitutes?

A: CKRB2430P mounting type is not specified in available data. DR2260A30U is specified for DIN Rail mounting. GNR30BCZH supports both Chassis Mount and DIN Rail configurations, providing greater installation flexibility.

Q: Is GNR30BCZH suitable for 24V input applications?

A: No. GNR30BCZH input voltage range is 80-140VAC, which does not accommodate 24V input. This substitute is limited to applications with input voltages between 80-140VAC.

Q: Are all three parts RoHS compliant?

A: Yes. CKRB2430P, DR2260A30U, and GNR30BCZH are all RoHS Compliant. GNR30BCZH additionally carries REACH Unaffected status.

Q: What load voltage ranges do these parts support?

A: CKRB2430P load voltage range is not specified. DR2260A30U supports 48-600V. GNR30BCZH supports 48-660V. Both substitutes provide extended load voltage capability compared to the main part specification.

Q: Can these parts be used interchangeably in the same circuit board layout?

A: Physical package differences exist. CKRB2430P and DR2260A30U both feature SSR with Integrated Heat Sink design. GNR30BCZH uses a Module package design. Mechanical compatibility must be verified against specific mounting requirements and thermal management needs of the application.
