Sensata-Crydom 84137032 SSR Relay SPST-NO 75A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137032 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration in a hockey puck package. This active product is designed for AC load switching applications with zero-cross detection. The part operates with an input voltage range of 18–36VAC and supports output loads from 24V to 280V at 75A maximum current. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata-Crydom 84137032 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must support AC switching with zero-cross detection for compatible load control
• Package Type: Must be hockey puck format to ensure mechanical fit in chassis mount applications
• Termination Style: Must use screw terminals for direct connection compatibility
• Load Current Capability: Must meet or exceed 75A rating
• Load Voltage Range: Must encompass or exceed the 24V–280V operating window
• Input Voltage Compatibility: Must accept control signals within or overlapping the 18–36VAC range
• Compliance: Must maintain RoHS compliance status for regulatory alignment

The Crouzet 84138153N meets these substitution criteria with enhanced performance specifications while maintaining functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84137032 and Crouzet 84138153N are active products with RoHS compliance, ensuring regulatory alignment for current and future applications. The Crouzet 84138153N provides enhanced electrical performance with a higher load current rating (90A versus 75A) and extended load voltage range (24V–500V versus 24V–280V), making it suitable for applications requiring additional headroom or higher voltage operation. The input voltage range of the Crouzet part (20–260VAC/DC) is broader than the original (18–36VAC), providing greater flexibility in control signal sourcing. Both parts maintain identical circuit configuration, output type, package format, and termination style, ensuring direct mechanical and functional compatibility in chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N directly replace the Sensata-Crydom 84137032?

A: Yes. Both parts share identical SPST-NO circuit configuration, AC zero-cross output type, hockey puck package format, chassis mount design, and screw terminal termination. The Crouzet part meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two parts?

A: The Crouzet 84138153N offers higher load current capacity (90A versus 75A), extended load voltage range (24V–500V versus 24V–280V), and broader input voltage compatibility (20–260VAC/DC versus 18–36VAC). These represent performance enhancements rather than functional changes.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use identical hockey puck package format and chassis mount configuration with screw terminal termination, ensuring direct mechanical fit and connection compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Sensata-Crydom 84137032 and Crouzet 84138153N are RoHS compliant and active products, meeting current regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications operating within the original specifications (75A maximum, 24V–280V load range, 18–36VAC control), either part is suitable. For applications requiring higher current capacity, extended voltage range, or broader input voltage tolerance, the Crouzet 84138153N is the appropriate choice.
