SMR4890-6 Equivalent & Substitute Parts

Part Overview

The SMR4890-6 is a solid state relay (SSR) manufactured by Sensata-Crydom, designed for high-current AC switching applications. This hockey puck-style relay operates with DC input control (8-32VDC) and manages AC loads up to 90A across a voltage range of 96-530V. The device features zero-cross switching for AC output control and utilizes screw terminal connections for permanent installation in chassis-mounted configurations. As an active product with ROHS3 compliance and REACH affected status, the SMR4890-6 remains in production. Equivalent and substitute parts are identified when operational parameters align within acceptable tolerances for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMR4890-6 is determined by alignment across the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must utilize hockey puck form factor with chassis mount configuration to ensure mechanical fit within existing installations.

Electrical Interface: Input voltage range (8-32VDC for SMR4890-6) and output switching type (AC with zero-cross capability) must be compatible or overlapping to maintain control circuit and load switching integrity.

Load Handling Capacity: Load current rating and voltage range determine whether a substitute can safely manage the intended AC load. The SMR4890-6 handles 90A at 96-530V; substitutes must support equivalent or higher current capacity within overlapping or compatible voltage ranges.

Termination and Circuit Configuration: Screw terminal connections and circuit topology (SPST-NO or equivalent switching function) ensure proper installation and operational behavior.

Regulatory and Compliance Status: Active product status and alignment with RoHS and REACH requirements ensure availability and regulatory acceptability in target markets.

The substitute part 84139130N (Crouzet GNS series) meets these criteria with compatible package, mounting, input voltage range, output type, and termination style, though with reduced current capacity (75A vs. 90A) and a narrower load voltage range (150-510V vs. 96-530V).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The SMR4890-6 remains the specified component for applications requiring 90A load current capacity across the full 96-530V voltage range with 8-32VDC control input. Active product status and ROHS3 compliance ensure continued availability and regulatory alignment.

Substitute Consideration: The Crouzet 84139130N (GNS series) serves as a functional substitute for applications where load current does not exceed 75A and load voltage remains within the 150-510V range. The substitute maintains compatibility in package form, mounting configuration, control input voltage (8-30VDC, overlapping with the primary part's 8-32VDC range), output switching type (AC, zero-cross), and termination style (screw terminal). Both parts carry active product status and meet applicable RoHS requirements. The Crouzet part carries REACH Unaffected status, which may provide regulatory advantage in certain supply chain contexts compared to the REACH Affected status of the primary part.

Application Constraints: Substitution is not appropriate for applications requiring the full 90A current capacity or load voltages below 150V or above 510V. In such cases, the SMR4890-6 must be retained as the sole suitable component.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84139130N replace the SMR4890-6 in all applications?

A: No. The Crouzet substitute is suitable only for applications where load current does not exceed 75A and load voltage falls within 150-510V. Applications requiring 90A capacity or operation below 150V or above 510V must use the SMR4890-6.

Q: Are the input voltage ranges compatible between these parts?

A: The ranges are substantially compatible. The SMR4890-6 accepts 8-32VDC input, while the Crouzet 84139130N accepts 8-30VDC input. Both overlap across the 8-30VDC range. Applications using input voltages between 30-32VDC require the SMR4890-6.

Q: Do both parts use the same package and mounting configuration?

A: Yes. Both the SMR4890-6 and Crouzet 84139130N utilize hockey puck form factor with chassis mount configuration, ensuring mechanical compatibility in existing installations.

Q: What is the significance of the REACH status difference?

A: The SMR4890-6 carries REACH Affected status, indicating the substance is subject to REACH regulation. The Crouzet 84139130N carries REACH Unaffected status. For supply chains operating in REACH-regulated regions, the Crouzet part may present simplified compliance documentation requirements.

Q: Are both parts RoHS compliant?

A: Yes. The SMR4890-6 is ROHS3 Compliant, and the Crouzet 84139130N is RoHS Compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What switching function does each part provide?

A: Both parts provide AC output switching with zero-cross capability. The Crouzet part is explicitly specified as SPST-NO (1 Form A) configuration. The SMR4890-6 circuit type is not specified in available documentation but operates as an AC zero-cross relay.
