GNR35DHZ Equivalent & Substitute Parts

Part Overview

The GNR35DHZ is a Solid State Relay (SSR) SPST-NO module manufactured by Sensata-Crydom, rated for 35A load current with input voltage range of 4–32VDC and output voltage range of 48–600V. This component features DIN Rail mounting, screw terminal connections, and zero-cross AC output switching. The part is designated as Last Time Buy, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure continued availability and system continuity for applications currently using this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GNR35DHZ is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Switching: AC with zero-cross capability
• Input Voltage Range: 4–32VDC
• Load Voltage Range: Minimum 48V; maximum 600V
• Load Current Rating: 35A or higher
• Mounting Interface: DIN Rail compatibility
• Termination: Screw Terminal connections

Two substitute parts meet these criteria with the following considerations:

DR2260D35U (Sensata-Crydom): Matches all electrical parameters identically. Differs in package configuration (integrated heat sink) and compliance status (ROHS3 vs. RoHS). Maintains DIN Rail mounting and screw terminal termination.

GNR45DCZP (Crouzet): Matches circuit type, input voltage, output type, mounting flexibility, and termination. Load current rating is 32A (below the 35A requirement) and maximum load voltage is 500V (below the 600V maximum). This part is suitable only for applications not requiring the full 35A capacity or 600V maximum voltage.

Parameter Comparison

Engineering Selection Recommendations

DR2260D35U is the primary direct substitute. It maintains identical electrical specifications (35A at 48–600V), input voltage range, and termination interface. The integrated heat sink provides enhanced thermal management compared to the standard module package. Both parts are RoHS compliant; DR2260D35U carries ROHS3 certification, representing a more recent compliance standard. Active product status ensures continued availability and supply chain stability.

GNR45DCZP is a secondary option suitable only for applications where load current does not exceed 32A and maximum load voltage does not exceed 500V. This part offers the advantage of dual mounting flexibility (Chassis Mount and DIN Rail). Use this substitute only when application requirements fall within these reduced electrical limits.

For applications requiring the full 35A capacity at voltages up to 600V, DR2260D35U is the recommended substitute.

Frequently Asked Questions (FAQ)

Q: Can GNR45DCZP replace GNR35DHZ in all applications?

A: No. GNR45DCZP has a maximum load current of 32A (versus 35A) and maximum load voltage of 500V (versus 600V). It is suitable only for applications operating within these reduced limits.

Q: What is the primary advantage of DR2260D35U over GNR35DHZ?

A: DR2260D35U includes an integrated heat sink, improving thermal dissipation during continuous operation. Electrical specifications are identical, and the part maintains active product status.

Q: Are both substitute parts DIN Rail compatible?

A: Yes. Both DR2260D35U and GNR45DCZP support DIN Rail mounting. GNR45DCZP additionally supports Chassis Mount configuration.

Q: Do the substitute parts use the same termination style?

A: Yes. All three parts (GNR35DHZ, DR2260D35U, and GNR45DCZP) use screw terminal connections, ensuring compatibility with existing wiring harnesses.

Q: What is the difference in RoHS compliance between the parts?

A: GNR35DHZ and GNR45DCZP are RoHS Compliant. DR2260D35U is ROHS3 Compliant, representing a more recent regulatory standard. Both certifications meet current environmental requirements.

Q: Why is GNR35DHZ marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory is available for final orders, but long-term availability is not guaranteed. Transition to an active substitute part is recommended for future designs.
