Sensata-Crydom 84137142 SSR Relay SPST-NO 100A 48-660V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137142 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 18–36VAC and supports load voltages from 48V to 660V at 100A capacity. The device features zero-cross switching for AC output control and screw terminal connections for industrial applications. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata-Crydom 84137142 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 capability
• Package Type: Must be hockey puck form factor for mechanical compatibility
• Mounting Type: Must be chassis mount to fit existing installations
• Termination Style: Must use screw terminals for connection compatibility
• Load Current Capacity: Substitute must meet or exceed 100A rating
• Load Voltage Range: Substitute must cover the 48V–660V operating window
• Input Voltage Compatibility: Substitute input voltage must overlap with or encompass the 18–36VAC range
• Product Status: Must be active to ensure ongoing availability and support
• Compliance: Must maintain RoHS compliance for regulatory alignment

The substitute part 84138153N (Crouzet GN+ series) meets these criteria with allowable parameter variations within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 84138153N is an active, RoHS-compliant substitute for the Sensata-Crydom 84137142. Both devices maintain identical circuit configuration, output switching characteristics, package form factor, and termination methodology. The substitute part extends input voltage compatibility to include DC operation (20–260VAC/DC) compared to the main part's AC-only input specification.

Selection between these parts must account for the following parameter differences:

• Load Current: The substitute is rated at 90A versus the main part's 100A. Applications requiring the full 100A capacity must use the original part.
• Load Voltage Maximum: The substitute supports up to 500V, while the main part extends to 660V. Applications exceeding 500V load voltage must use the original part.

Both parts are suitable for applications operating within the substitute's electrical envelope (90A maximum current, 24–500V load voltage range, 20–260VAC/DC input).

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N directly replace the Sensata-Crydom 84137142 in all applications?

A: Direct replacement is possible only if the application operates within the substitute's rated parameters: load current ≤90A and load voltage ≤500V. Applications requiring 100A capacity or load voltages above 500V must use the original part.

Q: Are the hockey puck packages mechanically identical?

A: Both parts use hockey puck form factor with chassis mount configuration and screw terminal connections. Mechanical compatibility is confirmed for standard mounting applications.

Q: What is the difference in input voltage specifications?

A: The main part accepts 18–36VAC input only. The substitute accepts 20–260VAC/DC, providing broader input voltage compatibility including DC operation. Both specifications overlap in the 20–36VAC range.

Q: Do both parts support zero-cross switching?

A: Yes. Both the Sensata-Crydom 84137142 and Crouzet 84138153N feature AC output type with zero-cross switching capability for synchronized load control.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are RoHS compliant and carry MSL rating 1 (Unlimited), meeting current regulatory requirements for industrial applications.

Q: What is the significance of the GN and GN+ series designations?

A: The GN series (main part) and GN+ series (substitute) indicate product line variants within their respective manufacturers' portfolios. Both series maintain SPST-NO solid-state relay architecture with compatible electrical and mechanical characteristics.
