D4890-10 Equivalent & Substitute Parts

Part Overview

The D4890-10 is a solid-state relay (SSR) manufactured by Sensata-Crydom, designed for AC load switching applications. This SPST-NO (1 Form A) hockey puck relay operates with DC input control (3–32VDC) and handles AC loads up to 90A at 80–530V. The product is currently active and available in bulk packaging with 1029 units in stock.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters: input voltage range, output voltage range, load current capacity, circuit configuration, and physical form factor. Substitutes enable procurement flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4890-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current: Must support 90A minimum
• Output Voltage Range: Must encompass or overlap the 80–530V range
• Input Voltage Range: Must accommodate 3–32VDC control signals
• Package / Case: Must be Hockey Puck form factor for mechanical compatibility
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal

The substitute part 84138150N (Crouzet GN+ series) meets these criteria with the following considerations: input voltage range (4–32VDC) overlaps the D4890-10 specification with a 1VDC minimum offset; output voltage range (24–500V) covers the critical operating band but does not extend to the full 80V minimum of the D4890-10. Load current capacity remains at 90A, and physical form factor, mounting, and termination are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the D4890-10 and 84138150N are active products with current manufacturing status and established supply chains. The D4890-10 maintains ROHS3 compliance and REACH Affected status. The 84138150N is RoHS Compliant with REACH Unaffected designation, offering regulatory flexibility in certain procurement contexts.

Selection between these parts should be based on application-specific voltage requirements. The D4890-10 supports the full 80–530V load range, while the 84138150N operates within 24–500V. For applications requiring operation below 24V load voltage, the D4890-10 is the appropriate choice. The 84138150N includes zero-cross switching capability, which may provide additional benefits in noise reduction for certain AC load types.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N replace the D4890-10 in all applications?

A: The 84138150N is functionally compatible for applications where the load voltage remains within 24–500V. Applications requiring operation at load voltages below 24V require the D4890-10.

Q: What is the significance of the zero-cross feature in the 84138150N?

A: Zero-cross switching synchronizes relay activation with AC voltage zero-crossing points, reducing electromagnetic interference and switching transients. This feature is not present in the D4890-10 but does not prevent substitution in standard applications.

Q: Are the input voltage ranges compatible?

A: The D4890-10 accepts 3–32VDC input, while the 84138150N accepts 4–32VDC. The 84138150N cannot be used in applications requiring control signals below 4VDC.

Q: Do both parts use identical physical mounting?

A: Yes. Both are hockey puck form factor with chassis mount configuration and screw terminal connections, ensuring mechanical interchangeability.

Q: What are the compliance differences?

A: The D4890-10 is ROHS3 Compliant and REACH Affected. The 84138150N is RoHS Compliant and REACH Unaffected. Selection may depend on regional regulatory requirements.
