Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD4875G-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Load Current Rating: Must be rated for 75 A minimum to handle the same load conditions
• Load Voltage Range: Must encompass or exceed the 48 V – 530 V operating window
• Input Control Voltage: Must accept 4 – 32 VDC control signal
• Output Type: Must be AC-rated for AC load switching applications
• Package and Mounting: Must use hockey puck package with chassis mount configuration and screw terminal termination for mechanical and electrical compatibility
• Compliance: Must maintain RoHS compliance status

The substitute part 84137330N (Crouzet GN series) meets all substitution criteria. It maintains identical circuit topology, load current rating, input voltage specification, package configuration, and termination style. The load voltage range extends to 660 V, which encompasses the required 48 V – 530 V window and provides additional operational margin.

Parameter Comparison

Engineering Selection Recommendations

Both the HD4875G-10 and 84137330N are active production components with RoHS compliance certification. The primary distinction is the load voltage range specification: the HD4875G-10 operates to 530 V, while the 84137330N extends to 660 V. For applications operating within the 48 V – 530 V window, either component is functionally equivalent. The Crouzet 84137330N provides additional voltage margin and may be selected when supply availability of the primary part is constrained. Both components share identical control voltage requirements, load current capacity, circuit topology, and mechanical form factor, ensuring direct functional substitution in chassis-mounted screw terminal installations.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137330N directly replace the Sensata-Crydom HD4875G-10?

A: Yes. Both components are SPST-NO solid state relays with 75 A load current rating, 4 – 32 VDC control input, AC output type, hockey puck package, and screw terminal termination. The Crouzet part's 660 V load voltage rating encompasses the HD4875G-10's 530 V specification, ensuring functional compatibility in all applications within the original voltage window.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts use identical hockey puck package configuration with chassis mount design and screw terminal termination. Physical dimensions and mounting interfaces are compatible for direct substitution without mechanical modification.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the HD4875G-10 and 84137330N are RoHS compliant and carry active product status, meeting current regulatory and supply chain requirements.

Q: What is the significance of the extended voltage range on the Crouzet part?

A: The Crouzet 84137330N's 660 V maximum load voltage rating provides operational margin beyond the HD4875G-10's 530 V specification. This extended range does not affect compatibility for applications operating within the original 48 V – 530 V window and may provide additional design flexibility for future applications.

Q: Are control voltage and load current specifications identical between these parts?

A: Yes. Both components require 4 – 32 VDC control input and are rated for 75 A load current, ensuring identical electrical interface requirements and load handling capacity.
