CKRB6020P Equivalent & Substitute Parts

Part Overview

The CKRB6020P 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 is needed to meet project timelines and cost objectives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB6020P is determined by the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) topology
• Load current rating: 20 A minimum
• Load voltage range: Minimum 48 V, maximum 660 V
• Output switching type: AC with zero-cross capability
• Termination interface: Screw terminal connection
• Physical form factor: SSR module with integrated heat sink

Parts meeting all these criteria are considered direct functional equivalents. The substitute parts identified—DR2260A20U and GNR20BCZH—satisfy these core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

DR2260A20U is the manufacturer-recommended substitute from Sensata-Crydom. This part maintains the same manufacturer lineage and shares identical load current and output switching characteristics. The load voltage range of 48-600V is slightly reduced compared to the CKRB6020P (48-660V), which may be a limiting factor in applications requiring operation above 600V. This part carries Active product status and is RoHS3 compliant.

GNR20BCZH, manufactured by Crouzet, provides an alternative from a different manufacturer while maintaining all critical electrical parameters. This part supports the full 48-660V load voltage range and offers flexible mounting options (Chassis Mount and DIN Rail). It is RoHS compliant and carries Active product status. The package classification differs (Module versus SSR with Integrated Heat Sink), which may affect thermal management characteristics in specific applications.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20U replace CKRB6020P in all applications?

A: DR2260A20U is functionally equivalent for applications operating within the 48-600V load voltage range. Applications requiring operation above 600V must use CKRB6020P or GNR20BCZH.

Q: What is the primary difference between DR2260A20U and GNR20BCZH?

A: Both parts share identical circuit topology, load current, and zero-cross AC output characteristics. The key differences are manufacturer (Sensata-Crydom versus Crouzet), load voltage range (600V versus 660V maximum), and mounting flexibility (DIN Rail only versus Chassis Mount and DIN Rail options).

Q: Are there input voltage differences between these parts?

A: Yes. CKRB6020P input voltage is not specified in available data. DR2260A20U operates on 90-280VAC/DC input. GNR20BCZH operates on 80-140VAC input. Verify input voltage compatibility with your control circuit before substitution.

Q: Do all three parts use screw terminal connections?

A: Yes. All three parts—CKRB6020P, DR2260A20U, and GNR20BCZH—use screw terminal termination style, ensuring compatibility with existing wiring harnesses.

Q: What compliance certifications apply to these parts?

A: DR2260A20U is RoHS3 compliant and REACH affected. GNR20BCZH is RoHS compliant and REACH unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction.
