Key Parameters

Substitute Part Grouping Explanation

Substitution of the Sensata-Crydom 84137332 is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Package Form Factor: Hockey puck package with chassis mount capability
• Termination Interface: Screw terminal connection
• Load Current Capacity: Minimum 75A rating required
• Load Voltage Range: Minimum coverage of 48-660V AC output
• Input Control Voltage: Compatible control signal range
• Output Type: AC output capability
• Compliance: RoHS compliance and MSL Level 1 rating

The substitute part Crouzet 84138153N meets these criteria with enhanced specifications in load current (90A) and input voltage flexibility (20-260VAC/DC), while maintaining the same package form factor, termination style, and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom 84137332 and Crouzet 84138153N are active products with RoHS compliance and MSL Level 1 ratings, qualifying them for equivalent selection in applications requiring SPST-NO solid-state relay functionality in hockey puck form factor.

The Crouzet 84138153N provides higher load current capacity (90A versus 75A) and extended input voltage range (20-260VAC/DC versus 18-36VAC), offering design flexibility for applications with variable control signal sources. The load voltage range of the Crouzet part (24-500V) covers the lower portion of the Sensata-Crydom specification (48-660V); applications requiring operation above 500V load voltage must use the Sensata-Crydom 84137332.

Both parts maintain identical package form factor, mounting configuration, and termination interface, ensuring mechanical and electrical compatibility within their respective rated parameters.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N replace the Sensata-Crydom 84137332 in all applications?

A: The Crouzet part is suitable for applications where the load voltage does not exceed 500V. Applications requiring load voltages between 500V and 660V must use the Sensata-Crydom 84137332.

Q: What is the significance of the zero-cross feature in the Crouzet part?

A: Zero-cross switching is a feature of the Crouzet 84138153N that synchronizes relay switching with AC voltage zero crossings. This parameter is provided in the component specifications and may influence switching characteristics in specific applications.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts use hockey puck package form factor with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility in applications designed for either component.

Q: What input voltage range applies to each part?

A: The Sensata-Crydom 84137332 requires 18-36VAC control input. The Crouzet 84138153N accepts 20-260VAC/DC control input, providing broader compatibility with variable control signal sources.

Q: Do both parts meet the same compliance requirements?

A: Both parts are RoHS compliant with MSL Level 1 rating. The Crouzet part additionally carries REACH Unaffected status.
