Key Parameters

Substitute Part Grouping Explanation

The GN325DSZH qualifies as a substitute based on the following critical parameters:

• Circuit Configuration: Both parts maintain 3PST-NO (3 Form A) topology, ensuring identical switching logic and contact arrangement.
• Input Voltage Range: Both accept 4–32VDC control signals, enabling direct integration into existing control circuits.
• Load Current Rating: Both are rated for 25A continuous switching, maintaining equivalent power handling capacity.
• Output Type: Both feature AC output with zero-cross switching, preserving load protection and EMI characteristics.
• Termination Style: Both use screw terminals, allowing direct connection without adapter requirements.
• Compliance: Both are RoHS compliant, meeting regulatory requirements for the target application.

The GN325DSZH operates within a load voltage range of 24–510V, which overlaps the primary operating window of the GN325DLZ (48–600V). Applications requiring voltages below 48V or above 510V must use the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (GN325DLZ): Select this part for applications requiring DIN rail mounting and load voltages spanning the full 48–600V range. This configuration is optimized for standard industrial control panel installations.

Substitute Part (GN325DSZH): This part is suitable for applications where chassis or panel mounting is acceptable and load voltages remain within the 24–510V window. Both parts carry active product status and current compliance certifications, ensuring long-term availability and regulatory alignment.

The choice between these parts is determined by mechanical mounting requirements and the specific load voltage range of the application. Both parts satisfy identical electrical switching requirements and control signal specifications.

Frequently Asked Questions (FAQ)

Q: Can the GN325DSZH replace the GN325DLZ in all applications?

A: The GN325DSZH is electrically equivalent for applications where load voltages remain between 24–510V and chassis or panel mounting is acceptable. Applications requiring DIN rail mounting or load voltages above 510V must use the GN325DLZ.

Q: Are the input control signals identical between these parts?

A: Yes. Both parts accept 4–32VDC input signals and feature identical 3PST-NO switching logic, allowing direct substitution in control circuits.

Q: What is the difference in mounting between these parts?

A: The GN325DLZ is designed for DIN rail mounting, standard in industrial control panels. The GN325DSZH supports chassis or panel mount configurations, requiring different mechanical installation approaches.

Q: Do both parts meet current RoHS requirements?

A: Yes. The GN325DLZ is RoHS Compliant, and the GN325DSZH is ROHS3 Compliant, both meeting current regulatory standards for restricted substances.

Q: What load voltage range should I use for substitution decisions?

A: The GN325DLZ covers 48–600V, while the GN325DSZH covers 24–510V. Verify your application's load voltage falls within the substitute part's range before selection.

Q: Are screw terminals compatible between these parts?

A: Yes. Both parts use screw terminal connections, allowing identical wiring practices without adapter requirements.
