Substitute Part Grouping Explanation

Substitute parts for the CKRB4820-10 are qualified based on the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 20 A minimum
• Load Voltage Range: Minimum 48 V lower bound with upper bound at or exceeding 530 V
• Output Type: AC switching capability
• Package Type: SSR with integrated heat sink
• Termination Style: Screw terminal connection
• Manufacturer: Sensata-Crydom product line

The DR2260A20UR meets all substitution criteria, offering equivalent switching performance with an extended load voltage range of 48-600V, providing additional operational margin.

Parameter Comparison

Engineering Selection Recommendations

Both the CKRB4820-10 and DR2260A20UR are active products from Sensata-Crydom with identical load current ratings and circuit configurations. The DR2260A20UR provides an extended load voltage range (48-600V versus 48-530V), offering additional operational headroom for applications approaching the upper voltage limit of the primary part.

The DR2260A20UR is RoHS compliant and specified for DIN Rail mounting, providing additional environmental and installation flexibility. Selection between these parts should be based on specific application voltage requirements and mounting infrastructure compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A20UR directly replace the CKRB4820-10 in all applications?

A: Yes, provided the application load voltage does not exceed 530V. The DR2260A20UR supports the full 48-530V range of the CKRB4820-10 and extends to 600V. Screw terminal connections and 20A current ratings are identical. Verify DIN Rail mounting compatibility with your installation framework.

Q: What is the significance of the extended voltage range in the DR2260A20UR?

A: The DR2260A20UR load voltage range of 48-600V encompasses the CKRB4820-10 specification of 48-530V. This extended range provides operational margin for applications operating near the upper voltage boundary and reduces the risk of exceeding component ratings in variable load conditions.

Q: Are there input voltage differences between these parts?

A: The DR2260A20UR specifies input voltage as 90-280VAC/DC. The CKRB4820-10 input voltage specification is not provided in the available data. Confirm input voltage compatibility with your control circuit before substitution.

Q: Does RoHS compliance affect substitution decisions?

A: The DR2260A20UR is RoHS compliant. If your application or regulatory framework requires RoHS compliance, the DR2260A20UR is the appropriate selection. The CKRB4820-10 RoHS status is not specified in available documentation.

Q: Are there packaging or inventory considerations?

A: The CKRB4820-10 is available in 761 units as new original stock. The DR2260A20UR is available in 1079 units in bulk packaging. Both are active products. Packaging format should be verified against your procurement and assembly requirements.
