Sensata-Crydom 84137111H Solid State Relay - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137111H is an active, production-status solid state relay (SSR) with SPST-NO (1 Form A) switching configuration. This hockey puck-style relay is designed for AC load switching applications requiring 25A capacity across a 48V to 660V load voltage range. The part operates with 90–280VAC input control voltage and incorporates zero-cross switching for AC output control. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific packaging requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 84137111H is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Load Current Rating: Must be rated for 25 A minimum to support the same load capacity
• Output Type: Must be AC with zero-cross switching for compatible control behavior
• Package / Case: Must be hockey puck form factor for mechanical fit in chassis mount applications
• Termination Style: Must use screw terminal connections for direct wiring compatibility
• Load Voltage Range: Must encompass or exceed the 48V–660V operating window
• Input Voltage Range: Must accommodate the 90–280VAC control signal specification
• RoHS Compliance: Must maintain RoHS compliance status for regulatory consistency

The Crouzet 84138013N meets these substitution criteria with the following considerations: it operates across a 12V–270V load voltage range (narrower than the main part) and accepts 20–265VAC/DC input control voltage (slightly different input specification). Both parts share identical circuit topology, current rating, output switching type, package form factor, and termination method.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84137111H and Crouzet 84138013N are active, production-status components with RoHS compliance. Selection between these parts depends on application load voltage requirements:

• Use 84137111H when load voltage operation spans the full 48V–660V range, particularly for high-voltage AC switching applications above 270V.
• Use 84138013N when load voltage operation remains within the 12V–270V range and input control voltage can be supplied at 20–265VAC/DC.

Both parts maintain identical switching topology, current capacity, output control characteristics, and mechanical form factor. The primary differentiation is load voltage operating range and input control voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138013N replace the Sensata-Crydom 84137111H in all applications?

A: The Crouzet part is functionally compatible only when the load voltage requirement does not exceed 270V. Applications requiring load voltages above 270V must use the Sensata-Crydom 84137111H, which is rated to 660V.

Q: Are the input control voltage ranges interchangeable?

A: The input voltage ranges differ slightly. The 84137111H accepts 90–280VAC, while the 84138013N accepts 20–265VAC/DC. Verify that your control signal source falls within the specified range of the selected part.

Q: Do both parts use the same mechanical mounting and termination?

A: Yes. Both parts are hockey puck form factor with chassis mount configuration and screw terminal connections, ensuring identical mechanical compatibility and wiring interface.

Q: What is the significance of the series designation (GN vs. GN+)?

A: The series designation indicates the product line. Both GN and GN+ series maintain the same functional specifications for this substitution comparison.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The Crouzet part additionally carries REACH Unaffected status. Both meet the same regulatory requirements for industrial SSR applications.
