GNR10ACZ Equivalent & Substitute Parts

Part Overview

The GNR10ACZ is a Solid State Relay (SSR) SPST-NO module manufactured by Sensata-Crydom, rated for 10A load current with input voltage range of 180–280VAC and load voltage range of 24–280V. This component features DIN Rail mounting, screw terminal connections, and zero-cross AC output switching. The product is designated as Last Time Buy, indicating discontinued production status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the GNR10ACZ is determined by compatibility across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Output Switching: AC with zero-cross capability required
• Mounting Interface: DIN Rail compatibility
• Termination: Screw terminal connection standard
• Input Voltage Range: 180–280VAC input specification
• Load Voltage Range: Minimum 24V to maximum 280V capability
• Load Current Rating: Minimum 10A capacity

The substitute parts identified (DR2260A20V and GNR20ACZH) exceed the load current specification (20A vs. 10A) and support higher load voltage ranges, making them suitable for applications requiring the GNR10ACZ while providing additional capacity margin. Both maintain the required circuit topology, output type, mounting standard, and termination style.

Parameter Comparison

Engineering Selection Recommendations

DR2260A20V is an active product from Sensata Technologies with ROHS3 compliance and REACH affected status. It provides 20A load current capacity with extended input voltage range (90–280VAC/DC) and load voltage range (48–600V). The integrated heat sink design supports higher thermal dissipation. This part is suitable for applications where the GNR10ACZ is no longer available and where the extended voltage and current specifications do not conflict with system design constraints.

GNR20ACZH is an active product from Crouzet with RoHS compliance and REACH unaffected status. It maintains the same input voltage range as the GNR10ACZ (180–280VAC) while providing 20A load current and extended load voltage range (48–660V). Dual mounting options (Chassis Mount and DIN Rail) provide installation flexibility. This part is suitable for direct substitution in applications where the GNR10ACZ specifications are met and where the higher current rating provides operational margin.

Both substitute parts maintain the required SPST-NO circuit topology, AC zero-cross output switching, screw terminal termination, and DIN Rail mounting compatibility. Selection between DR2260A20V and GNR20ACZH depends on input voltage range requirements (90–280VAC/DC vs. 180–280VAC), load voltage ceiling (600V vs. 660V), thermal management needs, and compliance documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20V and GNR20ACZH be used interchangeably with GNR10ACZ?

A: Both parts maintain the same circuit topology (SPST-NO), output type (AC zero-cross), mounting standard (DIN Rail), and termination style (screw terminal). However, they differ in input voltage range, load voltage range, and current rating. Verify that your application's input voltage, load voltage, and current requirements fall within the specifications of the selected substitute before implementation.

Q: What is the difference in input voltage capability between the substitute parts?

A: DR2260A20V accepts 90–280VAC/DC input, while GNR20ACZH accepts 180–280VAC input. If your application requires input voltage below 180VAC, DR2260A20V is the appropriate selection. If your application operates only within 180–280VAC, both parts are compatible.

Q: Why do the substitute parts have higher load current ratings than the GNR10ACZ?

A: Both DR2260A20V and GNR20ACZH are rated for 20A load current, compared to the GNR10ACZ's 10A rating. This higher capacity provides operational margin and allows these parts to serve applications with current requirements up to 20A. For applications requiring exactly 10A or less, the higher rating does not create incompatibility; it represents additional available capacity.

Q: What is the significance of the integrated heat sink in DR2260A20V?

A: The integrated heat sink in DR2260A20V provides enhanced thermal dissipation for higher current applications. This design feature supports sustained operation at the 20A rating with improved thermal management compared to module-only designs. Selection depends on your application's thermal environment and sustained current requirements.

Q: Are there packaging differences between these parts?

A: GNR10ACZ and GNR20ACZH are both supplied as modules. DR2260A20V is supplied as an SSR with integrated heat sink. GNR20ACZH offers dual mounting options (Chassis Mount and DIN Rail), while GNR10ACZ and DR2260A20V are DIN Rail only. Verify mounting compatibility with your installation requirements.

Q: What compliance certifications apply to each part?

A: GNR10ACZ is RoHS Compliant. DR2260A20V is ROHS3 Compliant and REACH Affected. GNR20ACZH is RoHS Compliant and REACH Unaffected. Confirm that the compliance status of your selected substitute meets your regulatory and procurement requirements.
