GNR20BHZ Equivalent & Substitute Parts

Part Overview

The GNR20BHZ is a Solid State Relay (SSR) SPST-NO module manufactured by Sensata-Crydom, rated for 20A load current with input voltage range of 90–140VAC and output voltage range of 48–600V. The device features zero-cross switching for AC loads and screw terminal connections suitable for DIN Rail mounting.

The GNR20BHZ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GNR20BHZ is determined by electrical and mechanical compatibility across the following parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Load Current Rating: 20A minimum capacity required
• Output Voltage Range: Minimum 48V to 600V or higher
• Input Voltage Compatibility: Substitute must accept the control signal voltage range
• Switching Characteristic: AC zero-cross switching required
• Mounting and Termination: DIN Rail compatible with screw terminal connections
• Regulatory Compliance: RoHS compliance status

Two substitute parts meet these criteria: the DR2260A20U (Sensata-Crydom, active status) and the GNR20BCZH (Crouzet, active status).

Parameter Comparison

Engineering Selection Recommendations

DR2260A20U (Sensata-Crydom)

The DR2260A20U is an active product from the original manufacturer with ROHS3 compliance. It features an integrated heat sink, which provides enhanced thermal management compared to the GNR20BHZ. The input voltage range extends to 280VAC/DC, offering broader control signal compatibility. This part is suitable for applications requiring extended input voltage tolerance or improved thermal performance.

GNR20BCZH (Crouzet)

The GNR20BCZH is an active product with RoHS compliance and maintains the same series designation as the GNR20BHZ. It supports both chassis mount and DIN Rail mounting configurations and offers a marginally higher output voltage rating (660V vs. 600V). This part provides direct functional equivalence with minimal design modification requirements.

Both substitutes maintain electrical and mechanical compatibility with the GNR20BHZ across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the DR2260A20U be used as a direct replacement for the GNR20BHZ?

A: Yes. Both parts share identical circuit topology (SPST-NO), load current rating (20A), output voltage range (48–600V minimum), and termination style (screw terminal). The DR2260A20U accepts a broader input voltage range (90–280VAC/DC vs. 90–140VAC) and includes an integrated heat sink. DIN Rail mounting is supported by both.

Q: Can the GNR20BCZH be used as a direct replacement for the GNR20BHZ?

A: Yes. Both parts share identical circuit topology (SPST-NO), load current rating (20A), output voltage range (48–600V+), and termination style (screw terminal). The GNR20BCZH supports both chassis mount and DIN Rail configurations. Input voltage range is 80–140VAC, which overlaps with the GNR20BHZ specification.

Q: What is the primary difference between the two substitute parts?

A: The DR2260A20U features an integrated heat sink and accepts a wider input voltage range (90–280VAC/DC). The GNR20BCZH maintains a module-based package design and supports dual mounting configurations (chassis and DIN Rail). Both are active products with current manufacturer support.

Q: Are there packaging or inventory considerations for these substitutes?

A: The DR2260A20U is supplied in bulk packaging. The GNR20BCZH is supplied in box packaging. Both are available in production quantities.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. The DR2260A20U carries ROHS3 compliance. The GNR20BCZH carries RoHS compliance. Both meet regulatory requirements for restricted substance elimination.
