Substitute Part Grouping Explanation

Substitute parts for the CKRB4830P are qualified based on the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 30 A minimum
• Load Voltage Range: Minimum 530 V upper limit (or higher)
• Output Type: AC with Zero Cross switching
• Termination: Screw Terminal connection
• Package Form: SSR module with integrated heat sink or equivalent thermal management
• RoHS Compliance: Required for regulatory alignment

Two substitute parts meet these criteria: DR2260A30U (Sensata-Crydom, DR22 series) and GNR30BCZH (Crouzet, GNR series). Both maintain the 30 A load current specification and exceed the minimum 530 V load voltage requirement, with DR2260A30U supporting 48-600V and GNR30BCZH supporting 48-660V.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CKRB4830P, DR2260A30U, and GNR30BCZH—are active products with RoHS compliance and meet the core electrical requirements for SPST-NO 30A AC switching applications. Selection between these parts should be based on:

Voltage Margin: DR2260A30U and GNR30BCZH both provide higher maximum load voltage ratings (600V and 660V respectively) compared to the CKRB4830P (530V), offering additional design margin for applications operating near the upper voltage limit.

Mounting Compatibility: DR2260A30U and GNR30BCZH both support DIN Rail mounting, enabling standardized panel integration. GNR30BCZH additionally supports Chassis Mount configuration, providing flexibility for non-standard installations.

Regulatory Compliance: All three parts maintain RoHS compliance. GNR30BCZH includes REACH Unaffected status, providing additional environmental documentation for regulated markets.

Inventory Availability: CKRB4830P has 794 units in stock, DR2260A30U has 715 units, and GNR30BCZH has 1151 units available.

Frequently Asked Questions (FAQ)

Q: Can DR2260A30U directly replace CKRB4830P in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current (30 A), output type (AC, Zero Cross), and termination style (Screw Terminal). DR2260A30U supports a higher maximum load voltage (600V vs. 530V), ensuring compatibility with the CKRB4830P's operating range.

Q: What is the primary difference between DR2260A30U and GNR30BCZH?

A: Both parts meet the core electrical specifications. The primary differences are manufacturer (Sensata-Crydom vs. Crouzet), maximum load voltage (600V vs. 660V), and mounting options. GNR30BCZH supports both Chassis Mount and DIN Rail, while DR2260A30U supports DIN Rail only.

Q: Are there input voltage differences between these parts?

A: Yes. CKRB4830P does not specify input voltage. DR2260A30U accepts 90-280VAC/DC input, while GNR30BCZH accepts 80-140VAC input. Verify input voltage compatibility with your control circuit before selection.

Q: Do all three parts require the same thermal management?

A: All three parts include integrated heat sink design. Mounting configuration may affect thermal performance; DIN Rail and Chassis Mount options provide different thermal dissipation characteristics depending on installation environment.

Q: Are these parts suitable for international applications?

A: All three parts are RoHS compliant. GNR30BCZH includes REACH Unaffected status. Verify ECCN and HTSUS classifications (all three are EAR99 and 8536.49.0080) for specific export or import requirements in your target market.
