GNR35DHR Solid State Relay - Equivalent & Substitute Parts

Part Overview

The GNR35DHR is a Solid State SPST-NO (1 Form A) relay module manufactured by Sensata-Crydom, rated for 35A load current with 48V to 600V output voltage capability and 4-32VDC input control voltage. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical performance characteristics while offering current manufacturing availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GNR35DHR are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 35 A minimum
• Load voltage range: 48 V ~ 600 V minimum
• Input voltage compatibility: 4 ~ 32 VDC or equivalent control voltage
• Output type: AC
• Mounting capability: DIN Rail compatible
• Termination: Screw Terminal

Substitute Categories:

Direct Electrical Equivalents (Full Parameter Match): DR2260D35UR and DR2260A35UR maintain identical load current (35A), load voltage range (48-600V), circuit configuration (SPST-NO), and termination style. Both are active products with integrated heat sink packaging.

Functional Equivalent (Reduced Load Voltage Range): GNR45DCZP provides SPST-NO configuration with 32A load current and 24-500V load voltage range. This part operates within the lower voltage spectrum of the original specification and supports both DIN Rail and Chassis Mount configurations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

DR2260D35UR and DR2260A35UR are active products that maintain full electrical equivalence to the GNR35DHR. Both parts preserve the 35A load current rating and 48-600V load voltage range. DR2260D35UR accepts 4-32VDC input control voltage, matching the original specification. DR2260A35UR accepts 90-280VAC/DC input control voltage, requiring verification of control signal compatibility in the target application. Both parts include integrated heat sink packaging, which may require mechanical accommodation in existing mounting structures. RoHS compliance is maintained across both options.

For Functional Substitution (Reduced Performance Envelope):

GNR45DCZP operates as a functional equivalent within applications where load current does not exceed 32A and load voltage remains below 500V. This part maintains SPST-NO configuration, 4-32VDC input control voltage, and screw terminal termination. The integrated zero-cross switching feature provides additional operational capability. Mounting flexibility includes both DIN Rail and Chassis Mount configurations. RoHS compliance is confirmed.

Selection Criteria:

Choose DR2260D35UR or DR2260A35UR when the application requires full 35A load current capacity and 48-600V load voltage range. Verify input control voltage compatibility: DR2260D35UR for 4-32VDC systems, DR2260A35UR for 90-280VAC/DC systems. Confirm mechanical accommodation for integrated heat sink packaging.

Choose GNR45DCZP only when application load current does not exceed 32A and load voltage remains within 24-500V range. This selection is appropriate for lower-power switching applications where the reduced performance envelope is acceptable.

Frequently Asked Questions (FAQ)

Q: Can DR2260D35UR directly replace GNR35DHR without circuit modification?

A: DR2260D35UR maintains identical electrical specifications (35A load current, 48-600V load voltage, 4-32VDC input, SPST-NO configuration, screw terminal termination). The primary difference is integrated heat sink packaging. Verify mechanical mounting space accommodates the heat sink assembly. No circuit modification is required if mounting space is available.

Q: What is the difference between DR2260D35UR and DR2260A35UR?

A: Both parts provide 35A load current and 48-600V load voltage capability. The critical difference is input control voltage: DR2260D35UR accepts 4-32VDC, while DR2260A35UR accepts 90-280VAC/DC. Select based on the control signal voltage available in your application. Verify control voltage compatibility before selection.

Q: Is GNR45DCZP suitable for all GNR35DHR applications?

A: GNR45DCZP is suitable only for applications where load current does not exceed 32A and load voltage remains below 500V. The original GNR35DHR supports 35A at up to 600V. If your application requires the full 35A capacity or operates above 500V load voltage, GNR45DCZP is not appropriate. Use DR2260D35UR or DR2260A35UR for full specification equivalence.

Q: Are all substitute parts RoHS compliant?

A: Yes. GNR35DHR, DR2260D35UR, DR2260A35UR, and GNR45DCZP are all RoHS Compliant.

Q: What mounting configurations are supported by each substitute?

A: GNR35DHR, DR2260D35UR, and DR2260A35UR support DIN Rail mounting. GNR45DCZP supports both DIN Rail and Chassis Mount configurations, providing additional flexibility for applications requiring chassis-level integration.

Q: Do the substitute parts include heat sink packaging?

A: DR2260D35UR and DR2260A35UR include integrated heat sink packaging. GNR35DHR and GNR45DCZP are standard module packages without integrated heat sinks. Verify thermal management requirements and available mounting space when selecting between heat sink and standard module configurations.
