GNR30BHZ Equivalent & Substitute Parts

Part Overview

The GNR30BHZ is a Solid State Relay (SSR) SPST-NO module manufactured by Sensata-Crydom, rated for 30A load current with output voltage range of 48V to 600V and zero-cross AC switching. The device features DIN Rail mounting and screw terminal connections, designed for industrial control applications requiring reliable solid-state switching without mechanical contacts.

The GNR30BHZ carries Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new system designs requiring compatible switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GNR30BHZ is determined by the following critical parameters:

Load Current Rating: All substitute parts must maintain the 30A load current specification to ensure equivalent thermal and switching performance in the target application.

Circuit Configuration: SPST-NO (1 Form A) topology is mandatory. This single-pole, single-throw normally-open configuration defines the control logic and cannot be altered in substitution.

Output Voltage Range: Substitute parts must support the full 48V to 600V output voltage window or a range that encompasses the application's operating voltage.

Output Type: AC switching with zero-cross detection is required to maintain synchronization with AC line voltage and reduce electromagnetic interference.

Mounting and Termination: DIN Rail mounting and screw terminal connections ensure mechanical and electrical compatibility with existing installations.

Compliance Status: RoHS compliance is mandatory for regulatory adherence in target markets.

The GNR30BHZ has two identified substitutes that meet these criteria: DR2260A30U (Sensata-Crydom) and GNR30BCZH (Crouzet). Both maintain the core electrical specifications while offering different form factors and input voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

DR2260A30U (Sensata-Crydom): This substitute is manufactured by the same supplier as the GNR30BHZ and maintains Active product status. The DR2260A30U features an integrated heat sink, which provides enhanced thermal management compared to the standard module form factor. The input voltage range extends to 280VAC/DC, offering broader control signal compatibility. This part is suitable for applications where the control signal may originate from either AC or DC sources within the specified range.

GNR30BCZH (Crouzet): This substitute is manufactured by Crouzet and maintains Active product status. The GNR30BCZH supports output voltage up to 660V, exceeding the GNR30BHZ specification by 60V. The input voltage range is 80–140VAC, which overlaps with the GNR30BHZ but does not extend to the higher AC voltages supported by the DR2260A30U. The GNR30BCZH offers dual mounting options (Chassis Mount and DIN Rail), providing installation flexibility. This part is suitable for applications requiring the extended output voltage capability or requiring chassis-mount installation.

Both substitutes maintain the critical electrical specifications: 30A load current, SPST-NO circuit configuration, AC zero-cross output type, and screw terminal connections. Selection between substitutes depends on control signal voltage requirements, thermal management needs, and mounting constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A30U replace the GNR30BHZ in all applications?

A: The DR2260A30U is electrically compatible with the GNR30BHZ for applications where the control signal is within 90–140VAC. The integrated heat sink in the DR2260A30U provides superior thermal performance. However, the DR2260A30U's form factor differs due to the integrated heat sink, which may affect physical installation space. Verify mounting clearance and thermal dissipation requirements before substitution.

Q: What is the advantage of the GNR30BCZH over the GNR30BHZ?

A: The GNR30BCZH supports output voltage up to 660V compared to the GNR30BHZ's 600V maximum, providing 60V additional headroom for high-voltage applications. The GNR30BCZH also offers dual mounting options (Chassis Mount and DIN Rail), whereas the GNR30BHZ supports DIN Rail only. Both maintain identical load current (30A) and circuit configuration (SPST-NO).

Q: Are all three parts RoHS compliant?

A: Yes. The GNR30BHZ, DR2260A30U, and GNR30BCZH are all RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions in target markets.

Q: Can I use the DR2260A30U with DC control signals?

A: Yes. The DR2260A30U input voltage range is specified as 90–280VAC/DC, indicating compatibility with both AC and DC control signals within this range. The GNR30BHZ and GNR30BCZH are specified for AC input only (90–140VAC and 80–140VAC respectively).

Q: What is the difference in packaging between these parts?

A: The GNR30BHZ and GNR30BCZH are supplied as standard modules. The DR2260A30U includes an integrated heat sink as part of the module assembly. Packaging format (Bulk vs. Box) affects order quantities and storage but does not affect electrical or mechanical compatibility.

Q: Which substitute should I select for a new design?

A: For new designs, select based on control signal voltage requirements and thermal environment. If control signals are AC only within 90–140VAC and thermal dissipation is adequate, the GNR30BCZH offers Active status and extended output voltage (660V). If control signals may include DC or exceed 140VAC, or if enhanced thermal management is required, the DR2260A30U is the appropriate choice.
