D4875-10 Equivalent & Substitute Parts

Part Overview

The D4875-10 is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a rated load current of 75A and operates across a voltage range of 80V to 530V. The device is actively produced and maintains full RoHS3 compliance and REACH affected status.

Identifying equivalent and substitute parts becomes necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4875-10 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be AC to match load switching requirements
• Load Current Rating: Must be rated for 75A continuous operation
• Input Voltage Range: Must accommodate 3 ~ 32VDC control signal
• Load Voltage Range: Must support operation within or exceed the 80V ~ 530V specification
• Package / Case: Must be hockey puck form factor for mechanical fit
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must use screw terminal connections

The substitute part 84137330N from Crouzet meets these criteria with the following considerations: it maintains identical circuit configuration, output type, load current, input voltage range, and package specifications. The load voltage range extends to 660V maximum, providing broader operational capability than the primary part's 530V maximum.

Parameter Comparison

Engineering Selection Recommendations

Both the D4875-10 and 84137330N are active production components with current availability. Selection between these parts should be based on the following factors:

D4875-10 (Sensata Technologies): Maintains RoHS3 compliance status and REACH affected classification. Suitable for applications requiring the specific 80V to 530V load voltage window.

84137330N (Crouzet): Maintains RoHS compliance and REACH unaffected status. Provides extended load voltage capability (48V to 660V), accommodating a broader range of AC load applications. The minimum input voltage specification of 4VDC (versus 3VDC) represents a negligible operational difference in most control circuit implementations.

Both components share identical circuit topology, current rating, and mechanical form factor, ensuring direct functional substitution within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the 84137330N replace the D4875-10 in all applications?

A: The 84137330N is functionally compatible with the D4875-10 for applications where the load voltage remains within both parts' overlapping range (80V to 530V). The extended voltage capability of the 84137330N (48V to 660V) does not create incompatibility; it provides additional operational flexibility. The 1VDC difference in minimum input voltage (4VDC versus 3VDC) is negligible in standard control circuits.

Q: Are there mechanical differences between the hockey puck packages?

A: Both parts use identical hockey puck form factors with chassis mount configuration and screw terminal termination. No mechanical modifications are required for substitution.

Q: What is the significance of the RoHS compliance difference?

A: The D4875-10 carries RoHS3 compliance, while the 84137330N carries RoHS compliance. Both meet current environmental and hazardous substance restrictions. Selection should align with specific regulatory requirements of the end application or region.

Q: Does the REACH status difference affect substitution?

A: The D4875-10 is REACH affected, while the 84137330N is REACH unaffected. This distinction reflects regulatory classification and does not impact electrical or mechanical performance. Selection should consider supply chain and regulatory documentation requirements specific to the application.

Q: What load voltage range should I use for compatibility verification?

A: For direct substitution, verify that your application's load voltage falls within the overlapping range of 80V to 530V. If your application requires voltages below 80V or between 530V and 660V, only the 84137330N is suitable.
