GNR20BCZ Equivalent & Substitute Parts

Part Overview

The GNR20BCZ is a solid-state relay (SSR) manufactured by Sensata-Crydom, designed as a SPST-NO (1 Form A) module for AC load switching applications. This component operates with input voltage ranges of 90–140VAC and supports load voltages from 48V to 600V at 20A capacity, utilizing zero-cross switching technology for AC applications. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for continued system operation and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GNR20BCZ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Output switching type: AC with zero-cross capability
• Load current rating: 20 A
• Load voltage range: minimum 48V to 600V support
• Input voltage compatibility: overlap with 90–140VAC specification
• Mounting interface: DIN Rail capability
• Termination: Screw Terminal

Identified Substitutes:

1. DR2260A20V (Sensata Technologies) – MFR Recommended: Meets all primary criteria with extended input voltage range (90–280VAC/DC) and load voltage support (48–600V). Active product status enables continued procurement.

2. GNR20BCZH (Crouzet) – Direct Equivalent: Maintains identical circuit configuration and electrical ratings with marginally extended load voltage ceiling (48–660V). Supports both DIN Rail and Chassis Mount configurations. Active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

DR2260A20V Selection Rationale: This part is designated as the MFR (Manufacturer) Recommended substitute. It maintains electrical equivalence across all critical parameters while offering extended input voltage tolerance (90–280VAC/DC versus 90–140VAC). The integrated heat sink design provides thermal management advantages for continuous-duty applications. Active product status ensures supply chain availability and ongoing manufacturer support. ROHS3 compliance aligns with current regulatory requirements.

GNR20BCZH Selection Rationale: This direct equivalent maintains the GNR series designation and provides functional parity with marginally enhanced load voltage capability (660V ceiling). The dual mounting configuration (Chassis Mount and DIN Rail) offers installation flexibility. Active product status and RoHS compliance support long-term deployment. This option is suitable for applications requiring form-factor consistency with the original GNR20BCZ.

Both substitutes are active products with current regulatory compliance, eliminating obsolescence risk associated with the original GNR20BCZ.

Frequently Asked Questions (FAQ)

Q: What makes DR2260A20V and GNR20BCZH suitable substitutes for GNR20BCZ?

A: Both parts maintain the critical electrical specifications: SPST-NO circuit configuration, 20A load current, AC zero-cross switching, and screw terminal termination. Load voltage ranges encompass or exceed the original 48–600V specification. Input voltage compatibility is confirmed within or overlapping the 90–140VAC requirement. Both support DIN Rail mounting and are active products with current compliance certifications.

Q: Are there differences in package configuration between these substitutes?

A: GNR20BCZH maintains the module package identical to GNR20BCZ. DR2260A20V features an integrated heat sink design, which provides enhanced thermal dissipation but may require verification of mounting clearance in existing installations. Both are suitable for DIN Rail applications.

Q: What is the significance of the extended input voltage range in DR2260A20V?

A: The DR2260A20V accepts 90–280VAC/DC input, compared to the original 90–140VAC specification. This extended range provides operational flexibility in systems with variable supply voltages but does not affect compatibility with standard 90–140VAC supplies. Selection should be based on actual system input voltage requirements.

Q: How do RoHS compliance statuses compare?

A: GNR20BCZ and DR2260A20V are both ROHS3 Compliant. GNR20BCZH is RoHS Compliant. All three meet current environmental and regulatory standards for electronic component manufacturing and deployment.

Q: Can GNR20BCZH be used in applications requiring Chassis Mount configuration?

A: Yes. GNR20BCZH supports both Chassis Mount and DIN Rail mounting types, providing installation flexibility beyond the DIN Rail-only capability of the original GNR20BCZ.
