Sensata-Crydom 84134032 SSR Relay SPST-NO 75A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84134032 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 of 18–36VAC and supports output loads from 24V to 280V at 75A capacity with zero-cross switching. The part is RoHS compliant and carries unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs.

Substitute Part Grouping Explanation

Substitution eligibility for the Sensata-Crydom 84134032 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 for compatible load control
• Package / Case: Must be hockey puck form factor for mechanical fit in chassis mount applications
• Termination Style: Must use screw terminal for direct connection compatibility
• Load Current Capacity: Must meet or exceed 75A rating
• Load Voltage Range: Must encompass or exceed the 24–280V operating window
• Input Voltage Compatibility: Must accept the 18–36VAC control signal or broader range
• Compliance: Must maintain RoHS compliance status

The substitute part 84138153N (Crouzet GN+ series) meets all substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 84138153N is a direct substitute for the Sensata-Crydom 84134032 based on matching circuit topology, output switching characteristics, and mechanical form factor. Both parts are active products with RoHS compliance certification. The Crouzet part offers enhanced electrical specifications: 90A load current capacity versus 75A, and 24–500V load voltage range versus 24–280V. The input voltage range of 20–260VAC/DC on the Crouzet part encompasses the 18–36VAC requirement of the original part. Both parts maintain identical SPST-NO switching logic, zero-cross AC output control, chassis mount configuration, hockey puck package, and screw terminal termination. Selection between these parts should be based on application load requirements, available inventory, and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N directly replace the Sensata-Crydom 84134032 in existing applications?

A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), package form factor (hockey puck), and termination style (screw terminal). The Crouzet part has higher current and voltage ratings, making it suitable for the same or more demanding applications.

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

A: The primary differences are load current capacity (90A vs. 75A), load voltage range (24–500V vs. 24–280V), and input voltage range (20–260VAC/DC vs. 18–36VAC). The Crouzet part provides broader electrical operating margins.

Q: Are both parts RoHS compliant?

A: Yes. Both the Sensata-Crydom 84134032 and Crouzet 84138153N are RoHS compliant and carry active product status.

Q: Does the hockey puck package ensure mechanical compatibility?

A: Yes. Both parts use identical hockey puck form factor and chassis mount configuration, ensuring mechanical fit in applications designed for either part.

Q: Can I use the Crouzet part in applications with lower current or voltage requirements than its rated capacity?

A: Yes. The Crouzet 84138153N can operate at any load current below 90A and any load voltage within the 24–500V range, making it suitable for applications requiring lower performance levels.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both parts use screw terminal termination style, ensuring direct connection compatibility without adapter requirements.
