Sensata-Crydom 4D2425G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 4D2425G is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 25A load current at 24V to 280V AC output. This chassis-mount relay features zero-cross switching and operates with 3V to 32VDC input control voltage. The 4D2425G is classified as obsolete product status. Locating equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and new production applications where this relay specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4D2425G is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Input voltage range: 3 ~ 32VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 25 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

The direct substitute D2425G from Sensata-Crydom meets all these criteria. This part maintains identical electrical specifications and mechanical form factor while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The D2425G is the direct functional equivalent to the 4D2425G. Both parts share identical electrical ratings, switching characteristics, and mechanical specifications. The primary distinction is product lifecycle status: the 4D2425G is obsolete while the D2425G maintains active status with current manufacturing support.

The D2425G provides enhanced compliance posture through ROHS3 certification and REACH Affected status, indicating alignment with current environmental and regulatory standards. For applications requiring long-term component availability and regulatory compliance documentation, the D2425G is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the D2425G directly replace the 4D2425G in existing applications?

A: Yes. The D2425G is electrically and mechanically equivalent. Both parts feature identical input voltage range (3 ~ 32VDC), load voltage range (24 V ~ 280 V), load current rating (25A), circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form (hockey puck). Direct substitution is supported without circuit modification.

Q: What is the difference between the 4D2425G and D2425G packaging?

A: The 4D2425G is supplied in standard packaging, while the D2425G is supplied in bulk packaging. Both parts use the identical hockey puck form factor and screw terminal configuration. Packaging difference does not affect electrical or mechanical compatibility.

Q: Why is the 4D2425G listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The D2425G represents the current active equivalent, ensuring access to ongoing manufacturing, technical support, and compliance documentation.

Q: Are there compliance differences between these parts?

A: The D2425G carries ROHS3 Compliant certification and REACH Affected status, reflecting current environmental regulations. The 4D2425G is listed as REACH Unaffected with unspecified RoHS status. For applications subject to environmental compliance requirements, the D2425G provides documented regulatory alignment.

Q: What is the inventory status for these parts?

A: The 4D2425G has 658 pieces in stock (new original). The D2425G has 973 pieces in stock (new original). Both parts are currently available.
