CKRB2410P Equivalent & Substitute Parts

Part Overview

The CKRB2410P is a Solid State SPST-NO (1 Form A) SSR relay manufactured by Sensata-Crydom, part of the CKR24 series. This component functions as a single-pole, single-throw normally open relay with integrated heat sink, designed for AC load switching applications. The part is currently in active inventory with 1031 units in stock. Substitute parts may be required due to supply constraints, application-specific voltage requirements, or load current specifications that exceed the main part's rated capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB2410P is determined by the following parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain functional equivalence
• Output Type: Must support AC switching with zero-cross capability
• Load Voltage Range: Substitute must accommodate the 24 V - 280 V operating window or provide a superset range
• Load Current Rating: Substitute must meet or exceed the 10 A requirement
• Package Type: SSR with integrated heat sink preferred for thermal management compatibility
• Termination Style: Screw terminal connection for direct replacement capability

Both identified substitutes (DR2260A20U and GNR20BCZH) meet these core criteria while offering enhanced current capacity and extended voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

DR2260A20U (Sensata-Crydom): This substitute maintains manufacturer continuity within the Sensata-Crydom product line. It provides doubled load current capacity (20 A vs. 10 A) and extended voltage range (48 V - 600 V), making it suitable for applications requiring higher switching capacity. The part is ROHS3 compliant and REACH affected, meeting current regulatory requirements. DIN Rail mounting is supported.

GNR20BCZH (Crouzet): This substitute offers equivalent current capacity (20 A) and extended voltage range (48 V - 660 V) with RoHS compliance and REACH unaffected status. The module package type and dual mounting options (Chassis Mount and DIN Rail) provide installation flexibility. This option is suitable when cross-manufacturer substitution is acceptable and regulatory status requires REACH unaffected components.

Both substitutes support zero-cross output switching, enhancing EMI performance compared to the main part specification.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20U or GNR20BCZH directly replace CKRB2410P in existing applications?

A: Both substitutes maintain SPST-NO circuit configuration and screw terminal termination, enabling direct replacement in most applications. However, the extended voltage ranges (48 V - 600 V and 48 V - 660 V respectively) require verification that the application's load voltage does not fall below 48 V, as the CKRB2410P supports operation down to 24 V.

Q: What is the advantage of the higher current rating in substitute parts?

A: The 20 A rating in both DR2260A20U and GNR20BCZH provides margin for applications with inrush current or future load expansion. The CKRB2410P's 10 A rating is suitable only for applications with confirmed maximum load current at or below 10 A.

Q: Are there differences in input voltage requirements?

A: The CKRB2410P input voltage specification is not provided in the available data. DR2260A20U supports 90 V - 280 VAC/DC input, while GNR20BCZH supports 80 V - 140 VAC input. Application input voltage must be verified against the selected substitute.

Q: What mounting considerations apply to these substitutes?

A: CKRB2410P mounting type is not specified. DR2260A20U supports DIN Rail mounting. GNR20BCZH supports both Chassis Mount and DIN Rail mounting, offering greater installation flexibility.

Q: How do RoHS and REACH compliance differ among these parts?

A: DR2260A20U is ROHS3 compliant and REACH affected. GNR20BCZH is RoHS compliant and REACH unaffected. Applications subject to REACH restrictions should specify GNR20BCZH; applications requiring ROHS3 certification should specify DR2260A20U.
