Equivalent & Substitute Parts for Sensata-Crydom 84134101 SSR Relay

Part Overview

The Sensata-Crydom 84134101 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 10A load current at 48V to 660V AC output. This active product is designed for chassis mount applications with screw terminal connections and zero-cross switching capability. Substitute parts are identified when inventory constraints, packaging requirements, or application-specific load current demands necessitate alternative component selection while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata-Crydom 84134101 is determined by the following critical parameters: circuit configuration (SPST-NO), output type (AC with zero-cross switching), load voltage range (48V to 660V), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The substitute part 84137111N (Crouzet) maintains all these core parameters. The primary difference is the load current rating, which increases from 10A to 25A. This higher current rating does not preclude substitution; a component rated for higher current can operate safely at lower current levels within its specified voltage and switching characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84134101 and Crouzet 84137111N are active products with RoHS compliance certification. The Crouzet 84137111N substitute provides a wider input voltage operating range (20V to 265VAC versus 90V to 280VAC) and increased load current capacity (25A versus 10A) while maintaining identical circuit topology, output switching characteristics, load voltage range, and mechanical form factor. Selection between these parts depends on application load current requirements and input voltage specifications. The higher current rating of the Crouzet part does not introduce incompatibility when applied to circuits designed for the original 10A specification.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137111N be used as a direct replacement for the Sensata-Crydom 84134101?

A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC zero-cross), load voltage range (48V to 660V), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The Crouzet part is rated for higher load current (25A versus 10A), which does not prevent substitution in applications designed for 10A operation.

Q: What is the difference in input voltage specifications between these parts?

A: The Sensata-Crydom 84134101 operates at 90V to 280VAC input, while the Crouzet 84137111N operates at 20V to 265VAC input. The Crouzet part accepts lower minimum input voltage but has a slightly lower maximum input voltage specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the Sensata-Crydom 84134101 and Crouzet 84137111N are RoHS compliant and active products.

Q: Does the higher current rating of the Crouzet part affect thermal performance in low-current applications?

A: This document provides only the electrical and mechanical parameters supplied in the component specifications. Thermal performance analysis requires detailed thermal modeling beyond the scope of this reference.

Q: Are there packaging differences between these parts?

A: The Sensata-Crydom 84134101 is supplied in bulk packaging, while the Crouzet 84137111N is supplied in box packaging. Both maintain identical hockey puck form factor and screw terminal configuration.
