Sensata-Crydom 84137000 SSR Relay SPST-NO 10A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137000 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, designed for AC load switching applications with zero-cross detection. This hockey puck-style relay operates with input voltage ranging from 3 to 32VDC and supports load voltages from 24V to 280V at 10A continuous current. The component is actively manufactured and maintains full RoHS3 compliance with REACH affected status. Substitute parts are identified when electrical specifications, mechanical form factor, and regulatory compliance align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84137000 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
• Output Type: AC switching with zero-cross detection capability
• Input Voltage Range: Minimum 3VDC to 4VDC; maximum 32VDC
• Load Voltage Range: 24V to 280V AC
• Load Current Rating: 10A continuous
• Package Form Factor: Hockey puck chassis-mount configuration
• Termination: Screw terminal interface
• Regulatory Compliance: RoHS compliance and REACH status

The substitute part 84137000N (Crouzet) meets these criteria with a minor variation in minimum input voltage (4VDC versus 3VDC), which represents a tighter but compatible specification for most industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 84137000 and 84137000N are active products with current manufacturing status. The primary distinction is the input voltage minimum specification: the 84137000 accepts 3VDC minimum input, while the 84137000N requires 4VDC minimum. For applications operating at or above 4VDC input, the 84137000N provides equivalent functionality. The 84137000 is required only when input voltage may drop below 4VDC. Both parts maintain RoHS compliance; the 84137000 carries RoHS3 certification while the 84137000N carries standard RoHS certification. REACH compliance differs: the 84137000 is REACH affected, while the 84137000N is REACH unaffected. Selection should account for regulatory requirements specific to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can the 84137000N replace the 84137000 in all applications?

A: The 84137000N is compatible with the 84137000 for applications where the control input voltage remains at 4VDC or higher. If the circuit design requires operation at 3VDC input, the original 84137000 must be used.

Q: What is the significance of the zero-cross output type?

A: Zero-cross detection ensures the relay switches AC loads only when the AC voltage waveform crosses zero, reducing electromagnetic interference and extending component life. Both substitute parts maintain this feature.

Q: Are the hockey puck packages mechanally interchangeable?

A: Yes. Both the 84137000 and 84137000N use identical hockey puck chassis-mount form factors with screw terminal connections, allowing direct mechanical substitution in existing mounting configurations.

Q: What is the difference between RoHS3 and RoHS compliance?

A: RoHS3 represents the current EU Restriction of Hazardous Substances directive with the most recent restrictions. Standard RoHS compliance indicates adherence to earlier directive versions. Both certifications restrict the same primary hazardous substances relevant to this component category.

Q: Does REACH compliance affect component selection?

A: REACH compliance status indicates regulatory obligations in specific markets. The 84137000 (REACH affected) may require additional documentation for European Union applications, while the 84137000N (REACH unaffected) does not. Selection depends on end-market regulatory requirements.

Q: Are both parts currently available?

A: Yes. The 84137000 maintains 808 units in stock, and the 84137000N maintains 843 units in stock as new original inventory.
