GNR30DHZ Solid State Relay - Equivalent & Substitute Parts

Part Overview

The GNR30DHZ is a Solid State Relay (SSR) manufactured by Sensata-Crydom, designed for SPST-NO (Single Pole Single Throw - Normally Open) switching applications. This module operates with AC output featuring zero-cross detection, rated for 30A load current across 48V to 600V output voltage range, with 4-32VDC input control voltage. The product is classified as Not For New Designs, making identification of active equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GNR30DHZ is determined by strict alignment of the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC with Zero Cross detection
• Input Voltage Range: 4 ~ 32VDC
• Load Voltage Range: Minimum 48V, maximum not less than 600V
• Load Current Rating: 30A
• Termination: Screw Terminal
• Mounting: DIN Rail compatible

Two substitute parts meet these criteria with full parameter alignment:

DR2260D30U (Sensata-Crydom, MFR Recommended) - Matches all critical parameters with integrated heat sink design and Active product status.

GNR30DCZH (Crouzet, Direct Manufacturer) - Matches all critical parameters with extended load voltage range (48-660V) and Active product status. Supports both Chassis Mount and DIN Rail mounting configurations.

Parameter Comparison

Engineering Selection Recommendations

DR2260D30U is the MFR (Manufacturer) Recommended substitute, maintaining Sensata-Crydom manufacturing continuity while offering Active product status. The integrated heat sink design provides enhanced thermal management compared to the standard module configuration. ROHS3 compliance is maintained. This option is optimal for direct replacement in existing Sensata-Crydom supply chains.

GNR30DCZH is the Direct Manufacturer alternative, manufactured by Crouzet under the GNR series designation. This part extends load voltage capability to 660V (versus 600V maximum on GNR30DHZ) and supports dual mounting configurations (Chassis Mount and DIN Rail). Product status is Active with RoHS compliance. This option provides expanded operational flexibility and mounting versatility.

Both substitutes maintain electrical and mechanical compatibility with the GNR30DHZ across all critical switching parameters. Selection between them depends on supply chain preference, thermal management requirements, and mounting configuration needs.

Frequently Asked Questions (FAQ)

Q: Can DR2260D30U replace GNR30DHZ in all applications?

A: Yes. DR2260D30U matches all critical electrical parameters (input voltage, load voltage, current rating, circuit configuration, output type) and termination style. The integrated heat sink is a design enhancement that does not affect compatibility. DIN Rail mounting is supported on both units.

Q: What is the difference between GNR30DCZH and GNR30DHZ?

A: Both are SPST-NO SSR modules with identical input/output voltage ranges, current ratings, and control specifications. GNR30DCZH is manufactured by Crouzet (versus Sensata-Crydom for GNR30DHZ), has Active product status (versus Not For New Designs), supports extended load voltage to 660V, and offers dual mounting options (Chassis Mount and DIN Rail).

Q: Are there thermal management differences between the substitutes?

A: DR2260D30U includes an integrated heat sink, providing enhanced thermal dissipation compared to the standard module design of GNR30DHZ and GNR30DCZH. Applications with high ambient temperatures or continuous operation may benefit from this feature.

Q: Can GNR30DCZH be mounted on a chassis in addition to DIN Rail?

A: Yes. GNR30DCZH supports both Chassis Mount and DIN Rail mounting configurations, providing installation flexibility not available with GNR30DHZ (DIN Rail only) or DR2260D30U (DIN Rail only).

Q: Are all three parts RoHS compliant?

A: Yes. GNR30DHZ and DR2260D30U are ROHS3 Compliant. GNR30DCZH is RoHS Compliant. All three meet environmental compliance requirements.

Q: What is the maximum load voltage for each part?

A: GNR30DHZ and DR2260D30U are rated to 600V maximum load voltage. GNR30DCZH is rated to 660V maximum load voltage, providing 60V additional headroom for higher voltage applications.
