Sensata-Crydom 84134141 SSR Relay SPST-NO 100A 48-660V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84134141 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 100A load current and operating voltage range of 48V to 660V. This hockey puck-style chassis mount relay is designed for AC applications with zero-cross switching capability. The part is currently active in production status with full RoHS3 compliance and REACH affected designation. Substitute parts are identified when equivalent electrical specifications and mechanical form factors are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84134141 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Load Current Rating: 100 A minimum capacity required
• Load Voltage Range: 48 V to 660 V operating window must be supported
• Output Type: AC with zero-cross switching functionality
• Package / Case: Hockey puck form factor for mechanical fit
• Termination Style: Screw terminal connection method
• Mounting Type: Chassis mount orientation

The substitute part 84137141N from Crouzet meets these core electrical and mechanical requirements, with the exception of input voltage range variation (20–265 VAC versus 90–280 VAC). This difference does not affect load-side functionality and represents an acceptable substitution within the specified parameter tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 84134141 and 84137141N are active production parts with established compliance certifications. The 84134141 carries RoHS3 compliance and REACH affected status, while the 84137141N provides RoHS compliance with REACH unaffected designation. Selection between these parts should be based on regulatory requirements specific to the end application and supply chain availability. The input voltage range difference (90–280 VAC versus 20–265 VAC) reflects manufacturer design variation and does not impact load-side electrical performance when the control circuit operates within either specified range.

Frequently Asked Questions (FAQ)

Q: Can the 84137141N directly replace the 84134141 in existing designs?

A: Yes, provided the control circuit input voltage operates within the 20–265 VAC range specified for the 84137141N. Both parts share identical load-side electrical ratings (100 A, 48–660 V) and mechanical form factor (hockey puck, screw terminal, chassis mount).

Q: What is the significance of the input voltage range difference?

A: The input voltage range specifies the control signal voltage required to activate the relay. The 84134141 requires 90–280 VAC, while the 84137141N operates on 20–265 VAC. This difference affects only the control circuit design and does not alter the load-side switching performance.

Q: Are there compliance differences between these parts?

A: The 84134141 is RoHS3 compliant and REACH affected. The 84137141N is RoHS compliant and REACH unaffected. Applications subject to REACH restrictions may benefit from the 84137141N designation, while RoHS3 requirements favor the 84134141.

Q: Do both parts use identical termination methods?

A: Yes, both the 84134141 and 84137141N employ screw terminal connections, ensuring mechanical compatibility in existing terminal block and wiring configurations.

Q: What packaging differences exist between these parts?

A: The 84134141 is supplied in bulk packaging, while the 84137141N is supplied in box packaging. This distinction affects receiving, storage, and inventory management but does not impact electrical or mechanical performance.
