Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata Technologies 84134082 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current Rating: Must be rated for minimum 125 A continuous operation
• Output Voltage Range: Must encompass or exceed the 24 V ~ 280 V operating window
• Input Voltage Range: Must be compatible with 18 ~ 36 VAC control signal
• Output Type: Must support AC zero-cross switching for synchronized load control
• Package / Case: Must be hockey puck form factor for mechanical compatibility
• Termination Style: Must use screw terminals for connection compatibility
• Mounting Type: Must support chassis mount installation

The Crouzet 84138183N meets all substitution criteria with enhanced specifications in output voltage range (24 V ~ 500 V) and input voltage flexibility (20 ~ 260 VAC/DC), while maintaining identical circuit configuration, current rating, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata Technologies 84134082 and Crouzet 84138183N are active products with RoHS compliance certification, ensuring regulatory alignment for industrial applications. The Crouzet 84138183N provides extended output voltage capability (500 V maximum versus 280 V) and broader input voltage acceptance (20 ~ 260 VAC/DC versus 18 ~ 36 VAC), offering greater operational flexibility for systems with variable supply conditions. Selection between these parts should be based on specific application voltage requirements and supply availability. Both maintain identical load current capacity, circuit topology, and physical form factor, ensuring direct functional equivalence within their respective voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138183N directly replace the Sensata 84134082 in all applications?

A: Yes, within the voltage operating parameters of the original application. The Crouzet part maintains identical circuit configuration (SPST-NO), load current rating (125 A), physical form factor (hockey puck), and termination style (screw terminal). The extended voltage ranges of the Crouzet part do not create incompatibility; they provide additional operational margin.

Q: What is the primary difference between these two SSR relay models?

A: The primary differences are output voltage range (Sensata: 24 V ~ 280 V; Crouzet: 24 V ~ 500 V) and input voltage range (Sensata: 18 ~ 36 VAC; Crouzet: 20 ~ 260 VAC/DC). Both parts are functionally equivalent for applications operating within the Sensata voltage specifications.

Q: Are both parts suitable for zero-cross switching applications?

A: Yes. Both the Sensata 84134082 and Crouzet 84138183N feature AC zero-cross output switching, enabling synchronized load control and reduced electromagnetic interference in AC circuit applications.

Q: Do packaging differences affect mechanical installation?

A: No. Both parts use identical hockey puck form factor and chassis mount configuration. Screw terminal connections are consistent between models, ensuring direct mechanical compatibility in existing installations.

Q: Are both parts RoHS compliant?

A: Yes. Both the Sensata 84134082 and Crouzet 84138183N carry RoHS compliance certification, meeting regulatory requirements for restricted substance elimination in electronic components.
