CKRB4810-10 Equivalent & Substitute Parts

Part Overview

The CKRB4810-10 is a Solid State SPST-NO (1 Form A) SSR relay manufactured by Sensata-Crydom, part of the CKR48 series. This component integrates a heat sink and is designed for applications requiring solid-state switching with no moving contacts. The part is currently in stock with 806 units available as new original inventory. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CKRB4810-10 must maintain functional equivalence based on the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC switching capability
• Package Type: SSR with integrated heat sink
• Manufacturer: Sensata-Crydom (same manufacturer ensures design compatibility)
• Load Current Rating: Equal to or greater than 10 A
• Load Voltage Range: Must encompass or exceed the 48 V ~ 530 V specification

The identified substitute DR2260A20UR meets these criteria while offering enhanced current capacity (20 A) and extended voltage range (48 V ~ 600 V), making it suitable for applications where the CKRB4810-10 may be unavailable.

Parameter Comparison

Engineering Selection Recommendations

The DR2260A20UR is an active, RoHS-compliant substitute for the CKRB4810-10. Both components share identical circuit topology (SPST-NO), output type (AC), and package configuration (SSR with integrated heat sink). The DR2260A20UR provides higher current capacity (20 A versus 10 A) and extended voltage range (600 V maximum versus 530 V maximum), making it electrically compatible for applications designed around the CKRB4810-10 specifications. The DIN Rail mounting and screw terminal configuration of the DR2260A20UR support standard industrial installation practices.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A20UR directly replace the CKRB4810-10 in existing applications?

A: Yes, the DR2260A20UR is functionally equivalent for SPST-NO AC switching applications. Both components share identical circuit topology and package type. The higher current rating (20 A) and extended voltage range (600 V) of the DR2260A20UR do not create incompatibility; they provide additional operational margin.

Q: What are the key differences between these two parts?

A: The primary differences are load current capacity (10 A versus 20 A) and maximum load voltage (530 V versus 600 V). The DR2260A20UR also specifies DIN Rail mounting and screw terminal termination, whereas these details are not provided for the CKRB4810-10.

Q: Are there any compliance or certification differences?

A: The DR2260A20UR is confirmed as RoHS Compliant and Active in product status. Compliance information for the CKRB4810-10 is not provided in the available data.

Q: What mounting and termination considerations apply to the DR2260A20UR?

A: The DR2260A20UR is specified for DIN Rail mounting with screw terminal connections, supporting standard industrial control panel installations.
