D2425S Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D2425S is an active Sensata Technologies solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration in a hockey puck package. This component is designed for AC load switching applications with zero-cross detection, rated for 25A load current across a 24V to 140V operating range. The relay accepts 3V to 32VDC input control signals and utilizes screw terminal connections for both control and load circuits. RoHS compliance and MSL Level 1 rating ensure suitability for standard industrial and commercial applications. Equivalent parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D2425S is determined by strict alignment across the following critical parameters:

Circuit and Switching Characteristics: The substitute part must maintain SPST-NO (1 Form A) configuration with AC output capability and zero-cross detection to ensure functional equivalence in switching applications.

Electrical Ratings: Load current capacity must equal or exceed 25A. Input voltage range must encompass the 3V to 32VDC control signal specification. Load voltage range must be compatible with or exceed the 24V to 140V operating window.

Physical and Mechanical Compatibility: Package type must be hockey puck format. Mounting configuration must support chassis mount installation. Termination must utilize screw terminals to ensure direct connection compatibility.

Compliance and Environmental: RoHS compliance status must match or exceed the main part specification. Moisture sensitivity level must be MSL 1 or equivalent to support standard handling and storage protocols.

The identified substitute part 84138010N (Crouzet GN+ series) meets all substitution criteria through equivalent circuit topology, matching load current rating, compatible input voltage range, extended load voltage capability, identical package and mounting specifications, and equivalent RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the D2425S and 84138010N are active products with current manufacturing status and full RoHS compliance certification. Selection between these components should be based on application-specific load voltage requirements and input voltage tolerance specifications.

The D2425S operates within a defined load voltage window of 24V to 140V with input control range of 3V to 32VDC. The 84138010N extends load voltage capability to 270V maximum while maintaining the same 25A current rating, with input control range of 4V to 32VDC. Applications requiring load voltages exceeding 140V or below 12V should utilize the 84138010N. Applications operating strictly within the 24V to 140V load range with input signals below 4VDC should retain the D2425S.

Both components maintain identical circuit topology, package format, mounting configuration, and termination style, ensuring mechanical and electrical interchangeability within their respective voltage operating windows.

Frequently Asked Questions (FAQ)

Q: Can the 84138010N replace the D2425S in all applications?

A: The 84138010N is functionally equivalent for applications where load voltage remains within the D2425S specification (24V to 140V) and input control voltage is 4VDC or higher. Applications requiring input signals below 4VDC must use the D2425S. Applications requiring load voltages below 12V or above 140V require the 84138010N.

Q: Are the physical dimensions and mounting footprints identical?

A: Both components utilize hockey puck package format with chassis mount configuration and screw terminal termination. Physical compatibility is confirmed for direct substitution in existing mounting hardware and terminal connections.

Q: What is the significance of zero-cross detection in these relays?

A: Zero-cross detection ensures the relay switches AC loads at the zero voltage crossing point, minimizing electrical noise, reducing electromagnetic interference, and extending load component lifespan by eliminating mid-cycle switching transients.

Q: Do both parts meet the same compliance requirements?

A: Both the D2425S and 84138010N are RoHS compliant with MSL Level 1 rating. The 84138010N carries additional REACH Unaffected certification. Both components meet standard industrial compliance requirements for their respective applications.

Q: What is the load current capacity, and can it be exceeded?

A: Both components are rated for 25A continuous load current. Operating above this specification will result in component failure and potential safety hazards. Load current must not exceed the 25A rating under any operating condition.

Q: How do input voltage ranges affect component selection?

A: The D2425S accepts input control signals from 3VDC to 32VDC. The 84138010N accepts 4VDC to 32VDC. If your control circuit generates signals below 4VDC, the D2425S is required. Both components operate identically within the 4VDC to 32VDC overlap range.
