Sensata-Crydom 84137900 SSR Relay SPST-NO 10A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84137900 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 10A load current at 24V to 280V AC output. This hockey puck-style chassis mount relay operates with 3V to 32VDC input control voltage and features screw terminal connections. The part is currently active in production and maintains ROHS3 compliance with REACH affected status. Substitute parts are identified when equivalent electrical specifications and mechanical form factors are required for component sourcing, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84137900 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Specifications: 10A current rating at 24V to 280V AC output
• Input Control Voltage: 3V to 32VDC range (or compatible subset)
• Package Form Factor: Hockey puck chassis mount with screw terminals
• Electrical Isolation: Solid-state relay technology with AC output capability

The substitute part 84137000N meets these core requirements while maintaining equivalent load handling capacity and input voltage compatibility within the specified ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the 84137900 and 84137000N are active production components with established compliance certifications. The Sensata-Crydom 84137900 carries ROHS3 compliance and REACH affected status. The Crouzet 84137000N carries RoHS compliance with REACH unaffected status. Selection between these parts should be based on regulatory requirements specific to the end application and supply chain availability. The Crouzet substitute includes zero-cross detection in its output type specification, which may provide additional switching characteristics for AC load applications. The input voltage range of the Crouzet part begins at 4VDC versus 3VDC for the Sensata-Crydom part, representing a minor operational constraint in applications requiring sub-4V control signals.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137000N directly replace the Sensata-Crydom 84137900 in existing designs?

A: Yes, both parts share identical load current (10A), load voltage range (24V–280V AC), package form factor (hockey puck), and termination style (screw terminal). The primary design consideration is the Crouzet part's minimum input voltage of 4VDC versus the Sensata-Crydom part's 3VDC minimum. Applications operating control signals below 4VDC require the original 84137900.

Q: What is the significance of zero-cross detection in the Crouzet substitute?

A: Zero-cross detection is an output characteristic that synchronizes relay switching with AC waveform zero-crossing points. This feature reduces electromagnetic interference and switching transients in AC load applications. The Sensata-Crydom 84137900 does not specify this feature.

Q: Are there compliance differences between these parts?

A: The Sensata-Crydom 84137900 is ROHS3 compliant and REACH affected. The Crouzet 84137000N is RoHS compliant and REACH unaffected. Applications subject to REACH regulations should verify applicability before substitution.

Q: Do both parts use identical screw terminal connections?

A: Both parts feature screw terminal connections in hockey puck packages. Physical terminal pitch and wire gauge compatibility should be verified during mechanical integration, though the specified package form factor indicates equivalent mechanical interfaces.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly processes.
