Sensata-Crydom 84137101 SSR Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137101 is an active solid-state relay (SSR) with SPST-NO (1 Form A) configuration, designed for AC load switching applications. This hockey puck-style relay operates with input voltage range of 90–280VAC and supports output loads from 48V to 660V at 10A capacity. The device features zero-cross switching for AC output control and is housed in a screw terminal hockey puck package. 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 84137101 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 with zero-cross switching capability
• Load Voltage Range: Must encompass or exceed 48V–660V specification
• Mounting and Termination: Must use chassis mount with screw terminal hockey puck package for mechanical compatibility
• RoHS Compliance: Must maintain RoHS compliance status for regulatory alignment

The substitute part 84137111N (Crouzet) meets these core substitution criteria. While it features a higher load current rating (25A versus 10A), this represents a performance upgrade that does not compromise compatibility. The input voltage range differs (20–265VAC versus 90–280VAC), but both ranges support standard industrial AC control circuits. Both parts maintain identical circuit configuration, output type, load voltage range, package style, and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84137101 and Crouzet 84137111N are active products with RoHS compliance, ensuring regulatory alignment and ongoing manufacturer support. The 84137111N substitute provides identical functional switching capability with enhanced current capacity (25A), making it suitable for applications requiring the original 10A specification or higher. The input voltage range of the 84137111N (20–265VAC) covers the lower end of the original specification (90–280VAC) and extends to lower thresholds, providing broader input compatibility in industrial control environments. Both parts maintain the same circuit topology, output switching characteristics, load voltage range, and mechanical form factor, ensuring direct functional substitution within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137111N directly replace the Sensata-Crydom 84137101?

A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC, zero-cross), load voltage range (48V–660V), and mechanical package (hockey puck with screw terminals). The 84137111N provides higher current capacity (25A) without compromising compatibility.

Q: What is the significance of the different load current ratings (10A vs. 25A)?

A: The 84137111N has a higher current rating, meaning it can safely handle loads up to 25A. Applications requiring only 10A will operate within the 84137111N's safe operating range. Higher current capacity does not create incompatibility; it represents a performance upgrade.

Q: How do the input voltage ranges differ, and does this affect substitution?

A: The original part accepts 90–280VAC input, while the substitute accepts 20–265VAC input. The substitute's range begins at a lower threshold (20VAC) but does not extend as high (265VAC vs. 280VAC). For standard industrial AC control circuits operating in the 90–265VAC range, both parts are functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the Sensata-Crydom 84137101 and Crouzet 84137111N are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

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

A: Yes. Both parts feature chassis mount configuration with screw terminal hockey puck packages, ensuring mechanical and electrical compatibility in existing installations.
