GNR45ACZ Equivalent & Substitute Parts

Part Overview

The GNR45ACZ is a Solid State Relay (SSR) SPST-NO module manufactured by Sensata-Crydom, rated for 45A load current with input voltage range of 180–280VAC and output voltage range of 48–600V. This component features zero-cross switching for AC loads and screw terminal connections suitable for DIN rail mounting.

The GNR45ACZ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GNR45ACZ is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) — substitute parts must maintain identical switching topology
• Load Current Rating: 45A — substitute parts must support this current capacity
• Output Voltage Range: 48–600V — substitute parts must accommodate this load voltage specification
• Output Type: AC with Zero Cross switching — substitute parts must provide identical switching characteristics
• Mounting Type: DIN Rail — substitute parts must support DIN rail installation
• Termination Style: Screw Terminal — substitute parts must use screw terminal connections

The substitute parts DR4560A45 and DR4560A45P meet all these criteria. Both are active products from Sensata-Crydom with identical electrical ratings and compatible mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both DR4560A45 and DR4560A45P are active products from Sensata-Crydom and serve as direct functional equivalents to the obsolete GNR45ACZ. Selection between the two substitute parts should be based on packaging and inventory requirements:

• DR4560A45: Available in bulk packaging with 770 units in stock. Moisture Sensitivity Level (MSL) is 1 (Unlimited).
• DR4560A45P: Available in bulk packaging with 869 units in stock. Moisture Sensitivity Level (MSL) is Not Applicable.

Both parts maintain identical electrical specifications and mechanical compatibility with the GNR45ACZ. The primary difference is the integrated heat sink design in the DR series compared to the module design of the GNR series, which provides improved thermal management for the same 45A load current rating.

Frequently Asked Questions (FAQ)

Q: Can DR4560A45 and DR4560A45P be used interchangeably with GNR45ACZ?

A: Yes. Both substitute parts maintain identical circuit configuration (SPST-NO), output type (AC, Zero Cross), load current rating (45A), output voltage range (48–600V), mounting type (DIN Rail), and termination style (Screw Terminal). Both are active products with RoHS compliance.

Q: What is the difference between DR4560A45 and DR4560A45P?

A: Both parts have identical electrical ratings and mechanical interfaces. The primary difference is Moisture Sensitivity Level (MSL): DR4560A45 has MSL 1 (Unlimited), while DR4560A45P has MSL Not Applicable. Packaging and inventory quantities also differ.

Q: Why does the input voltage range differ between GNR45ACZ and the substitute parts?

A: The GNR45ACZ specifies input voltage of 180–280VAC, while DR4560A45 and DR4560A45P specify 90–280VAC/DC. The substitute parts support a wider input range, making them compatible with the GNR45ACZ application requirements.

Q: Are the substitute parts suitable for DIN rail installation?

A: Yes. Both DR4560A45 and DR4560A45P are rated for DIN Rail mounting with screw terminal connections, maintaining mechanical compatibility with the GNR45ACZ.

Q: What certifications apply to these parts?

A: All three parts (GNR45ACZ, DR4560A45, and DR4560A45P) are RoHS Compliant with ECCN classification EAR99.
