Sensata-Crydom 84137182 SSR Relay SPST-NO 125A 48-660V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137182 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 125A load current and 48V to 660V output voltage range. This hockey puck-style chassis mount relay is designed for AC zero-cross switching applications with 18-36VAC input control voltage. The part is active in production status and RoHS compliant. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Sensata-Crydom 84137182 are identified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current Rating: Must be 125 A minimum
• Package / Case: Must be Hockey Puck form factor
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• Output Type: Must be AC with Zero Cross capability
• RoHS Compliance: Must be RoHS Compliant
• Product Status: Must be Active

The Crouzet 84138183N meets these core substitution criteria. While the input voltage range (20-260VAC/DC vs. 18-36VAC) and maximum load voltage (24-500V vs. 48-660V) differ, these represent design variations within the same product category and do not preclude substitution when the application load voltage and control voltage fall within the substitute part's rated ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84137182 and Crouzet 84138183N are active production parts with RoHS compliance and identical MSL ratings. Selection between these parts should be based on application-specific voltage requirements:

• Sensata-Crydom 84137182: Select when application load voltage exceeds 500V or when input control voltage is constrained to 18-36VAC range.
• Crouzet 84138183N: Select when application load voltage is 24-500V and input control voltage can be 20-260VAC/DC. This part offers broader input voltage flexibility including DC control options.

Both parts maintain identical load current capacity (125A), circuit configuration (SPST-NO), and mechanical form factor (hockey puck chassis mount with screw terminals). Compliance certifications (RoHS, ECCN EAR99) are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138183N replace the Sensata-Crydom 84137182 in all applications?

A: Substitution is valid only when the application load voltage remains within 24-500V and input control voltage is within 20-260VAC/DC. If the application requires load voltages above 500V, the Sensata-Crydom 84137182 is required.

Q: What is the significance of the different input voltage ranges?

A: The Sensata-Crydom 84137182 accepts 18-36VAC input, while the Crouzet 84138183N accepts 20-260VAC/DC input. The Crouzet part provides broader input flexibility, including DC control capability. Verify your control circuit voltage before substitution.

Q: Are the hockey puck packages physically identical?

A: Both parts use hockey puck form factor with chassis mount configuration and screw terminal termination. Physical mounting and electrical connection compatibility is maintained between these parts.

Q: Do both parts have the same load current rating?

A: Yes. Both the Sensata-Crydom 84137182 and Crouzet 84138183N are rated for 125A load current with AC zero-cross switching output type.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant with MSL rating of 1 (Unlimited) and ECCN classification EAR99. The Crouzet part carries additional REACH Unaffected status.
