CD2425W4V Equivalent & Substitute Parts

Part Overview

The CD2425W4V is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual Form A circuits. This component is designed for AC load switching applications with zero-cross detection capability. The device operates with input voltage ranging from 4 to 32VDC and supports load voltages between 24V and 280V at a maximum current of 25A. The product maintains Active status and is RoHS Compliant, making it suitable for modern industrial and commercial applications. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2425W4V is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2
• Output Type: AC, Zero Cross
• Load Voltage Range: 24V ~ 280V
• Load Current Rating: 25A
• Mounting Type: Chassis Mount
• Product Status: Active

Allowable Variation Parameters:

• Input Voltage Range: The substitute part (ASR-SID240D25ZL) operates within 4 ~ 15VDC, which is a subset of the main part's 4 ~ 32VDC range. This represents a more restrictive input specification but maintains compatibility in applications where input voltage does not exceed 15VDC.
• Termination Style: The substitute uses Quick Connect - 0.250" (6.3mm) instead of Screw Terminal. This represents a different connection method requiring appropriate connector compatibility in the application circuit.
• Package Type: The substitute is supplied in Module form rather than Hockey Puck form, affecting physical installation and thermal management considerations.

The ASR-SID240D25ZL meets all mandatory electrical and functional parameters while introducing variations in input voltage tolerance, termination interface, and physical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the CD2425W4V and ASR-SID240D25ZL maintain Active product status and meet current regulatory compliance requirements. The CD2425W4V carries RoHS Compliance certification, while the ASR-SID240D25ZL meets the more stringent ROHS3 Compliant standard. Both components are classified under ECCN EAR99 and share the same HTSUS code (8536.41.0060), indicating equivalent regulatory treatment for export and trade purposes.

Selection between these parts depends on application-specific constraints:

The CD2425W4V is appropriate for applications requiring input voltage operation up to 32VDC with screw terminal connectivity and Hockey Puck form factor integration.

The ASR-SID240D25ZL is appropriate for applications where input voltage does not exceed 15VDC, where Quick Connect termination is compatible with the circuit design, and where Module form factor meets physical installation requirements.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SID240D25ZL replace the CD2425W4V in all applications?

A: The ASR-SID240D25ZL is functionally equivalent for AC load switching at 25A with zero-cross detection. However, three factors require evaluation: (1) Input voltage must not exceed 15VDC; (2) Quick Connect - 0.250" (6.3mm) termination must be compatible with the circuit; (3) Module form factor must fit the physical installation space.

Q: What is the significance of the input voltage difference between these parts?

A: The CD2425W4V accepts input voltage from 4 to 32VDC, while the ASR-SID240D25ZL accepts 4 to 15VDC. If your application uses input voltage above 15VDC, the ASR-SID240D25ZL cannot be used. If your application uses input voltage at or below 15VDC, both parts are electrically compatible.

Q: Are the termination styles interchangeable?

A: No. The CD2425W4V uses Screw Terminal connections, while the ASR-SID240D25ZL uses Quick Connect - 0.250" (6.3mm) connectors. The circuit board or wiring harness must be designed to accommodate the specific termination style of the selected part.

Q: Do both parts have the same load switching capability?

A: Yes. Both parts are rated for 25A load current with load voltage range of 24V to 280V and feature AC output with zero-cross detection. The load-side electrical performance is identical.

Q: What is the difference between Hockey Puck and Module packaging?

A: Hockey Puck and Module refer to different physical form factors and mounting configurations. The Hockey Puck (CD2425W4V) and Module (ASR-SID240D25ZL) have different dimensions and thermal characteristics. Physical space constraints and heat dissipation requirements in your application determine which form factor is suitable.

Q: Are both parts RoHS compliant?

A: Yes. The CD2425W4V is RoHS Compliant, and the ASR-SID240D25ZL is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. ROHS3 represents a more recent compliance standard.
