CKRB6020 Equivalent & Substitute Parts

Part Overview

The CKRB6020 is a Solid State SPST-NO (1 Form A) SSR with integrated heat sink manufactured by Sensata-Crydom, part of the CKR60 series. This component is designed for applications requiring reliable switching of AC loads in the 48-660V range at 20A capacity. Finding equivalent and substitute parts is necessary when the primary part is unavailable, when supply chain optimization is required, or when alternative sourcing from qualified manufacturers is preferred while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB6020 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 20 A
• Load voltage range must encompass or match 48-660V
• Output type must be AC with zero-cross switching capability
• Package must provide integrated heat sink functionality
• Termination must be screw terminal type

The substitute parts identified—DR2260A20U (Sensata-Crydom, DR22 series) and GNR20BCZH (Crouzet, GNR series)—meet these core electrical and mechanical requirements, enabling direct functional replacement in applications designed for the CKRB6020.

Engineering Selection Recommendations

DR2260A20U is the primary manufacturer-recommended substitute, maintaining the same manufacturer lineage (Sensata-Crydom) and offering ROHS3 compliance with active product status. The load voltage range of 48-600V is suitable for applications not exceeding 600V. This part is optimized for DIN Rail mounting and represents the most direct functional equivalent.

GNR20BCZH from Crouzet provides an alternative from a different qualified manufacturer. It maintains full compatibility with the CKRB6020 across all critical electrical parameters and extends the load voltage range to 660V, matching the original specification. This part offers RoHS compliance and supports both chassis mount and DIN Rail configurations, providing greater mounting flexibility.

Selection between these substitutes should be based on application voltage requirements, mounting constraints, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20U replace CKRB6020 in all applications?

A: DR2260A20U is electrically compatible for applications operating at 600V or below. If your application requires operation above 600V up to 660V, GNR20BCZH is the appropriate choice.

Q: What is the difference between the package types listed?

A: CKRB6020 and DR2260A20U are specified as SSR with integrated heat sink. GNR20BCZH is specified as a Module. All three provide integrated thermal management and screw terminal connections. Mounting type differences (DIN Rail vs. Chassis Mount) affect installation method but not electrical function.

Q: Are all three parts RoHS compliant?

A: DR2260A20U is ROHS3 compliant. GNR20BCZH is RoHS compliant. RoHS status for CKRB6020 is not specified in the provided data.

Q: What input voltage range does each part support?

A: CKRB6020 input voltage is not specified. DR2260A20U supports 90-280VAC/DC input. GNR20BCZH supports 80-140VAC input. Verify input voltage compatibility with your control circuit before selection.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for the specified parameters. Physical mounting and input voltage requirements must be verified against your specific application design before implementation.
