CD4825W4V Equivalent & Substitute Parts

Part Overview

The CD4825W4V is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual-channel device. This active product operates with input voltage ranging from 4 to 32VDC and supports load voltages between 48V and 660V at 25A continuous current. The device features zero-cross switching for AC loads and employs screw terminal connections in a hockey puck package format suitable for chassis mounting. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters while meeting the same regulatory and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4825W4V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A) x 2 dual-channel topology
• Output switching type: AC with zero-cross capability
• Input voltage range: Must encompass or be compatible with 4 ~ 32VDC
• Load voltage range: Must encompass or be compatible with 48 V ~ 660 V
• Load current rating: Must meet or exceed 25A
• Termination: Screw terminal connection
• Product status: Active

Identified Substitutes:

1. 84140603N (Crouzet GN2 Series) – Meets all primary criteria with enhanced current rating (50A) and compatible voltage ranges. Input voltage 4 ~ 32VDC and load voltage 48 V ~ 660 V match the main part specification. Package format is Module with chassis or panel mount capability.

2. ASR-SID480D25ZL-S (Altran Magnetics SID Series) – Maintains dual SPST-NO configuration with matching 25A current rating. Input voltage range 4 ~ 15VDC is a subset of the main part's 4 ~ 32VDC range. Load voltage range 24 V ~ 530 V is a subset of 48 V ~ 660 V. Package format is Module with chassis mount.

Parameter Comparison

Engineering Selection Recommendations

84140603N (Crouzet GN2 Series) is the primary substitute option. This part maintains identical input and load voltage specifications (4 ~ 32VDC input, 48 V ~ 660 V load) and exceeds the current rating requirement at 50A versus 25A. Both parts are active products with current RoHS compliance certifications. The primary design consideration is package format transition from hockey puck to module, which may require mechanical redesign of mounting interfaces.

ASR-SID480D25ZL-S (Altran Magnetics SID Series) is a secondary substitute suitable for applications where input voltage does not exceed 15VDC and load voltage remains below 530V. This part maintains the 25A current rating and dual SPST-NO configuration. Both parts are active products with ROHS3 compliance. The narrower voltage specifications require application-level verification before implementation.

All three parts maintain active product status and current regulatory compliance, supporting long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can 84140603N directly replace CD4825W4V in all applications?

A: Electrical compatibility is confirmed across input voltage (4 ~ 32VDC), load voltage (48 V ~ 660 V), and switching characteristics (AC, zero-cross). The 50A current rating of 84140603N exceeds the 25A requirement. Physical package format differs (module versus hockey puck), requiring mechanical interface verification for your specific mounting configuration.

Q: What are the voltage limitations of ASR-SID480D25ZL-S?

A: Input voltage range is 4 ~ 15VDC (versus 4 ~ 32VDC for the main part) and load voltage range is 24 V ~ 530 V (versus 48 V ~ 660 V). This substitute is suitable only for applications operating within these narrower ranges. Applications requiring input voltages above 15VDC or load voltages above 530V must use the main part or 84140603N.

Q: Are all three parts RoHS compliant?

A: Yes. CD4825W4V is RoHS Compliant. Both 84140603N and ASR-SID480D25ZL-S are ROHS3 Compliant, representing current regulatory standards.

Q: What is the difference between hockey puck and module packages?

A: Package format affects physical dimensions and mounting interface design. Hockey puck (CD4825W4V) and module (84140603N, ASR-SID480D25ZL-S) formats require different mechanical mounting solutions. Verify your enclosure and mounting hardware compatibility before substitution.

Q: Do all parts use screw terminal connections?

A: Yes. CD4825W4V, 84140603N, and ASR-SID480D25ZL-S all employ screw terminal termination style, ensuring consistent wiring interface across substitution options.
