GN325DSZ Equivalent & Substitute Parts

Part Overview

The GN325DSZ is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) module. This component is designed for AC load switching applications with zero-cross detection, operating from 4–32VDC input control voltage and supporting loads up to 25A at 48–530V. The part is currently active in production status with 997 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GN325DSZ is determined by the following critical parameters:

• Circuit Configuration: Must be 3PST-NO (3 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross detection for compatible load control
• Voltage - Input: Must support 4–32VDC control voltage range
• Voltage - Load: Must support minimum 48V and maximum 530V load voltage envelope
• Load Current: Must be rated for 25A continuous operation
• Termination Style: Must use screw terminal connections for mechanical compatibility
• RoHS & REACH Compliance: Must meet or exceed the regulatory status of the main part

The GN325DSZH (Crouzet) meets these substitution criteria with the following considerations: input voltage range is identical (4–32VDC), load current rating is identical (25A), circuit configuration is identical (3PST-NO), output type is identical (AC, zero-cross), and termination is identical (screw terminal). The load voltage range for GN325DSZH is 24–510V, which overlaps the GN325DSZ range of 48–530V within the 48–510V intersection. Mounting type differs (chassis/panel mount vs. DIN rail), requiring mechanical integration assessment.

Parameter Comparison

Engineering Selection Recommendations

Both the GN325DSZ and GN325DSZH are active production parts with ROHS3 compliance. The GN325DSZH offers the additional advantage of REACH Unaffected status, which may simplify regulatory documentation in certain jurisdictions. Both parts maintain identical electrical specifications for input control voltage (4–32VDC), load current (25A), circuit topology (3PST-NO), and output switching characteristics (AC, zero-cross). The primary differentiation is mounting configuration: GN325DSZ is DIN rail mounted, while GN325DSZH supports chassis or panel mount installation. Load voltage compatibility exists within the 48–510V range for both parts. Selection between these parts should be based on mechanical mounting requirements and regulatory compliance needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can GN325DSZH replace GN325DSZ in a DIN rail installation?

A: GN325DSZH is specified for chassis or panel mount installation, not DIN rail. Mechanical compatibility must be verified before substitution in DIN rail applications.

Q: Are the input control voltage ranges identical between these parts?

A: Yes. Both GN325DSZ and GN325DSZH operate with 4–32VDC input control voltage.

Q: What is the load voltage overlap between these two parts?

A: GN325DSZ supports 48–530V and GN325DSZH supports 24–510V. The overlapping range is 48–510V, which is suitable for applications within this envelope.

Q: Do both parts have identical load current ratings?

A: Yes. Both parts are rated for 25A continuous load current.

Q: What is the difference in REACH compliance status?

A: GN325DSZ is REACH Affected, while GN325DSZH is REACH Unaffected. This may affect supply chain documentation and regulatory requirements depending on application location.

Q: Are the termination styles compatible?

A: Yes. Both parts use screw terminal connections, ensuring compatible wiring practices.

Q: Is the circuit configuration identical?

A: Yes. Both parts are configured as 3PST-NO (3 Form A) solid-state relays with AC zero-cross output switching.
