CKRB6010 Equivalent & Substitute Parts

Part Overview

The CKRB6010 is a Solid State SPST-NO (1 Form A) SSR relay manufactured by Sensata-Crydom, designed for applications requiring 10A switching capacity at 48-660V load voltage. This component integrates a heat sink for thermal management in industrial control and power switching applications. The part is currently in stock with 794 units available.

Substitute parts become necessary when the original CKRB6010 is unavailable, when higher current capacity is required, or when alternative sourcing is preferred while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CKRB6010 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Voltage Range: Must encompass or exceed the 48-660V specification
• Output Type: Must support AC with Zero Cross switching
• Termination Style: Must use Screw Terminal for mechanical compatibility
• Package Type: Must include integrated heat sink for thermal management
• Load Current: Substitute parts may have equal or higher current rating; lower ratings are not acceptable

The identified substitute parts meet these criteria while offering alternative sourcing options or enhanced current capacity.

Parameter Comparison

Engineering Selection Recommendations

DR2260A20U (Sensata-Crydom): This substitute maintains manufacturer continuity with Sensata-Crydom while providing doubled current capacity at 20A. The load voltage range of 48-600V covers the primary operating window of the CKRB6010, with the upper limit 60V lower than the original specification. DIN Rail mounting is supported. Product status is Active with ROHS3 compliance and REACH Affected designation.

GNR20BCZH (Crouzet): This substitute provides equivalent 20A current capacity with full load voltage coverage at 48-660V, matching the original specification ceiling. The component supports both Chassis Mount and DIN Rail configurations, offering greater installation flexibility. Product status is Active with RoHS compliance and REACH Unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20U replace CKRB6010 in all applications? A: DR2260A20U is functionally compatible for SPST-NO switching applications. The load voltage maximum of 600V is 60V lower than CKRB6010's 660V rating. Applications operating above 600V require GNR20BCZH or the original CKRB6010.

Q: What is the difference between the two substitute parts? A: Both DR2260A20U and GNR20BCZH provide 20A capacity and SPST-NO switching. DR2260A20U is Sensata-Crydom manufactured with 48-600V load range and DIN Rail mounting. GNR20BCZH is Crouzet manufactured with 48-660V load range and dual mounting options (Chassis Mount and DIN Rail).

Q: Does higher current rating affect compatibility? A: Substitute parts with equal or higher current ratings are compatible. The 20A rating of both substitutes exceeds the 10A requirement, providing additional capacity margin without affecting circuit functionality.

Q: Are there input voltage differences between these parts? A: DR2260A20U accepts 90-280VAC/DC input. GNR20BCZH accepts 80-140VAC input. Application input voltage requirements must align with the selected substitute's input specification.

Q: What compliance differences exist? A: DR2260A20U is ROHS3 Compliant and REACH Affected. GNR20BCZH is RoHS Compliant and REACH Unaffected. Selection depends on regulatory requirements for the end application.
