D2490-10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D2490-10 is an active, ROHS3-compliant solid state relay manufactured by Sensata Technologies. This SPST-NO (1 Form A) hockey puck relay is designed for AC load switching applications with a rated load current of 90 A and load voltage range of 24 V to 280 V. The part operates with a 3 to 32 VDC input signal and features screw terminal connections for chassis mount installation. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific requirements within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D2490-10 is determined by strict alignment with the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 90 A
• Package type must be Hockey Puck with screw terminal termination
• Mounting type must be Chassis Mount
• Output type must be AC or AC with additional switching features (zero cross)
• Load voltage range must encompass or exceed the minimum 24 V to 280 V specification
• Input voltage range must be compatible with 3 to 32 VDC operation

The substitute part 84138150N (Crouzet GN+ series) meets these criteria with the following considerations: it maintains identical circuit configuration, load current, package type, termination style, and mounting type. The load voltage range extends to 500 V, providing enhanced capability. Input voltage range is 4 to 32 VDC, which overlaps the D2490-10 specification with a minimum threshold 1 V higher. The substitute includes zero cross switching functionality in addition to standard AC output capability.

Parameter Comparison

Engineering Selection Recommendations

Both the D2490-10 and 84138150N are active products with confirmed regulatory compliance. The D2490-10 carries ROHS3 compliance status and is REACH Affected. The 84138150N is RoHS Compliant and REACH Unaffected. Selection between these parts should be based on application requirements and supply availability. The 84138150N provides extended load voltage capability (up to 500 V versus 280 V) and includes zero cross switching functionality, which may offer advantages in noise reduction for certain AC load applications. The D2490-10 operates with input voltage as low as 3 VDC, whereas the 84138150N minimum input is 4 VDC. Both parts are rated for 90 A load current and share identical mechanical form factors and termination methods.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N replace the D2490-10 in all applications?

A: The 84138150N is electrically and mechanically compatible with the D2490-10 for applications operating within the overlapping parameter ranges. The input voltage minimum difference (4 VDC versus 3 VDC) must be evaluated against your specific control circuit design. The extended load voltage range of the 84138150N does not create incompatibility; it provides additional operational margin.

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

A: Zero cross switching is an additional output capability that synchronizes relay switching with the AC load voltage zero crossing point. This feature reduces electromagnetic interference and switching transients. Applications not requiring this functionality will operate normally with the 84138150N; the feature does not affect basic SPST-NO switching performance.

Q: Are there packaging differences between these parts?

A: Both parts use Hockey Puck packaging with screw terminal connections and are rated for chassis mount installation. Packaging is functionally equivalent.

Q: What compliance differences exist between the D2490-10 and 84138150N?

A: The D2490-10 is ROHS3 Compliant and REACH Affected. The 84138150N is RoHS Compliant and REACH Unaffected. Selection should align with your product's regulatory requirements and target markets.

Q: How do the load voltage ranges compare?

A: The D2490-10 is rated for 24 V to 280 V AC loads. The 84138150N extends this range to 24 V to 500 V AC loads. Both parts operate within the 24 V to 280 V window; the 84138150N simply provides additional capability for higher voltage applications.
