D2425G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D2425G is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration with hockey puck form factor. This component is designed for AC load switching applications requiring 25A capacity across 24V to 280V load voltage ranges. The relay operates with 3V to 32VDC input control voltage and incorporates zero-cross switching for AC output control. As an active product with 973 units in current inventory, the D2425G remains available; however, equivalent alternatives exist for applications requiring specific compliance profiles, alternative input voltage ranges, or different packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D2425G is determined by strict alignment of the following electrical and mechanical parameters:

• Circuit configuration: SPST-NO (1 Form A) topology
• Output type: AC with zero-cross switching capability
• Load current rating: 25 A minimum
• Load voltage range: Minimum 24V support required
• Input control voltage: 3V to 32VDC compatible range
• Package form factor: Hockey puck chassis mount
• Termination: Screw terminal connection

The identified substitute parts meet these core requirements with the following considerations:

84137910N (Crouzet GNA Series): Meets all electrical specifications with input voltage range of 4V to 32VDC (higher minimum than D2425G) and identical load voltage/current ratings. RoHS compliant with REACH unaffected status.

ASR-SI240D25Z-LR (Altran Magnetics SI Series): Meets all electrical specifications with input voltage range of 4V to 32VDC and load voltage range of 48V to 280V (higher minimum than D2425G). ROHS3 compliant with REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

D2425G Selection: Appropriate for applications requiring input voltage control as low as 3VDC and load voltage as low as 24VDC. Maintains ROHS3 compliance. Note REACH affected status for supply chain documentation.

84137910N Selection: Suitable for applications where input control voltage minimum of 4VDC is acceptable. Offers REACH unaffected status, simplifying regulatory documentation. RoHS compliant (non-ROHS3). All electrical load parameters identical to D2425G.

ASR-SI240D25Z-LR Selection: Appropriate for applications where minimum load voltage of 48VDC is acceptable. Provides REACH unaffected status and ROHS3 compliance. Input voltage range identical to 84137910N at 4V to 32VDC minimum.

All three parts maintain active product status and identical 25A load current capacity with zero-cross AC switching output.

Frequently Asked Questions (FAQ)

Q: Can 84137910N replace D2425G in all applications? A: 84137910N is electrically compatible for applications where the control input voltage does not drop below 4VDC. The D2425G supports control inputs as low as 3VDC. Load voltage and current specifications are identical.

Q: What is the key difference between ASR-SI240D25Z-LR and the other two options? A: ASR-SI240D25Z-LR specifies a minimum load voltage of 48VDC, whereas both D2425G and 84137910N support loads starting at 24VDC. This part is suitable only for applications operating at 48V or higher load voltages.

Q: Are all three parts available in the same hockey puck package? A: Yes. All three parts use identical hockey puck form factor with chassis mount configuration and screw terminal termination.

Q: What is the significance of REACH affected versus REACH unaffected status? A: REACH affected status (D2425G) indicates the part may contain substances of concern requiring additional regulatory documentation. REACH unaffected status (84137910N and ASR-SI240D25Z-LR) simplifies compliance documentation for European supply chains.

Q: Can these parts be used interchangeably in existing designs? A: Interchangeability depends on specific application requirements. Verify that control input voltage range, load voltage range, and regulatory compliance requirements align with the selected substitute part specifications.
