GNR35DCZ Equivalent & Substitute Parts

Part Overview

The GNR35DCZ is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) module with DIN Rail mounting. It provides 35A load switching capability across 48V to 600V AC output with zero-cross detection, controlled by 4–32VDC input signals. The product carries Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure continued availability and support for existing designs and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GNR35DCZ are qualified based on the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC with zero-cross detection
• Load Current: 35 A nominal rating
• Voltage - Input: 4–32 VDC control signal range
• Voltage - Load: 48 V minimum to 600 V maximum AC output
• Mounting Type: DIN Rail compatibility
• Termination Style: Screw Terminal interface

Three substitute parts meet these criteria with allowable parameter variations:

DR2260D35V (Sensata-Crydom): Maintains identical input voltage range (4–32 VDC), load current (35 A), and output voltage window (48–600 V). Differs in package configuration (SSR with Integrated Heat Sink) and RoHS certification level (ROHS3).

DR2260A35V (Sensata-Crydom): Supports expanded input voltage range (90–280 VAC/DC) while maintaining 35 A load current and 48–600 V output voltage. Package includes integrated heat sink. RoHS Compliant status matches the main part.

GNR45DCZP (Crouzet): Provides 32 A load current (within acceptable tolerance for 35 A applications), identical input voltage range (4–32 VDC), and reduced output voltage window (24–500 V). Supports both DIN Rail and Chassis Mount configurations. RoHS Compliant.

Parameter Comparison

Engineering Selection Recommendations

DR2260D35V is the closest functional equivalent, maintaining all critical electrical parameters (35 A, 4–32 VDC input, 48–600 V output) with identical DIN Rail and screw terminal configuration. ROHS3 compliance exceeds RoHS requirements. This part is recommended for direct replacement in applications where the integrated heat sink does not present mechanical constraints.

DR2260A35V provides the same electrical performance as DR2260D35V with expanded input voltage flexibility (90–280 VAC/DC). This part is suitable for applications requiring AC or mixed AC/DC control signaling. RoHS Compliant status matches the original specification.

GNR45DCZP offers compatibility with reduced load current (32 A versus 35 A) and output voltage ceiling (500 V versus 600 V). This part is applicable only in applications where these reduced ratings remain within design margins. The dual mounting capability (DIN Rail and Chassis Mount) provides additional installation flexibility. All three substitute parts maintain active product status, ensuring ongoing availability and support.

Frequently Asked Questions (FAQ)

Q: Can DR2260D35V replace GNR35DCZ in all applications? A: DR2260D35V maintains identical load current (35 A), input voltage range (4–32 VDC), and output voltage window (48–600 V). The integrated heat sink packaging differs from the standard module case. Mechanical fit must be verified for the specific installation.

Q: What is the difference between DR2260D35V and DR2260A35V? A: Both parts provide 35 A load current and 48–600 V output voltage. DR2260A35V accepts input signals from 90–280 VAC/DC, while DR2260D35V requires 4–32 VDC. DR2260A35V is suitable for applications using AC control signals; DR2260D35V is limited to DC control.

Q: Can GNR45DCZP be used as a substitute for GNR35DCZ? A: GNR45DCZP provides 32 A load current and 24–500 V output voltage, both lower than the original 35 A and 48–600 V specifications. This part is compatible only if the application load current does not exceed 32 A and the maximum output voltage requirement does not exceed 500 V.

Q: Are all substitute parts RoHS compliant? A: Yes. GNR35DCZ, DR2260A35V, and GNR45DCZP are RoHS Compliant. DR2260D35V carries ROHS3 Compliant certification, which exceeds RoHS requirements.

Q: What is the significance of "Last Time Buy" status for GNR35DCZ? A: Last Time Buy indicates the manufacturer has discontinued production. Existing inventory is available for final orders only. Substitute parts with Active status (DR2260D35V, DR2260A35V, GNR45DCZP) ensure long-term availability for new designs and ongoing maintenance.

Q: Do all substitute parts use screw terminal connections? A: Yes. GNR35DCZ and all three substitute parts (DR2260D35V, DR2260A35V, GNR45DCZP) use screw terminal termination, ensuring compatibility with existing wiring harnesses.

Q: What is zero-cross detection in these SSR relays? A: Zero-cross detection synchronizes relay switching to the AC voltage zero-crossing point, reducing electromagnetic interference and switching transients. All parts in this comparison include this feature.
