CD2425W3V Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CD2425W3V is an active Solid State Relay (SSR) manufactured by Sensata-Crydom, designed for SPST-NO (Single Pole Single Throw - Normally Open) switching applications. This dual-channel relay operates with AC output featuring zero-cross switching capability, rated for 25A load current across a 24V to 280V range. The device is housed in a Hockey Puck package with screw terminal connections and is fully ROHS3 compliant. Substitute parts may be required due to inventory constraints, application-specific packaging preferences, or supply chain considerations while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2425W3V is determined by the following critical parameters that must remain equivalent:

• Circuit Configuration: SPST-NO (1 Form A) x 2 channels
• Output Type: AC with Zero Cross switching
• Load Current Rating: 25A minimum
• Load Voltage Range: 24V to 280V minimum coverage
• Mounting Type: Chassis Mount
• Compliance: ROHS3 Compliant status

The ASR-SID240D25ZL qualifies as a substitute based on matching these core electrical and mechanical specifications. Variations in input voltage range (4~15VDC vs. 4~32VDC), termination style (Quick Connect vs. Screw Terminal), and package form factor (Module vs. Hockey Puck) represent acceptable differences that do not affect functional equivalence for standard switching applications, provided the application's input voltage requirements fall within the substitute's 4~15VDC specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CD2425W3V and ASR-SID240D25ZL are active products with equivalent regulatory compliance (ROHS3 Compliant, REACH Unaffected, EAR99 classification). Selection between these parts should be based on the following engineering considerations:

CD2425W3V is the primary choice when:

• Input voltage requirements exceed 15VDC
• Screw terminal connections are specified in the design
• Hockey Puck form factor is required for mechanical fit

ASR-SID240D25ZL is suitable when:

• Input voltage remains within the 4~15VDC range
• Quick Connect termination is compatible with the application design
• Module form factor accommodates the installation space
• Inventory availability or supply chain requirements favor this alternative

Both parts maintain identical electrical performance for load switching (25A at 24~280V AC with zero-cross operation) and dual-channel SPST-NO configuration.

Frequently Asked Questions (FAQ)

Q: Can ASR-SID240D25ZL replace CD2425W3V in all applications?

A: Substitution is valid only when the application's input voltage requirement falls within 4~15VDC. If the design requires input voltages between 15VDC and 32VDC, the CD2425W3V must be used. Additionally, the termination method (Quick Connect vs. Screw Terminal) and package form factor must be compatible with the circuit board or chassis design.

Q: What is the significance of the different termination styles?

A: The CD2425W3V uses screw terminals for fixed wire connections, while the ASR-SID240D25ZL uses 0.250" (6.3mm) Quick Connect terminals. These require different connection hardware and installation procedures. The choice depends on whether the application design accommodates quick-disconnect connectors or requires permanent screw-based termination.

Q: Are the load switching specifications identical between these parts?

A: Yes. Both parts are rated for 25A load current across 24V to 280V AC with zero-cross switching. The dual-channel SPST-NO configuration is identical. Differences in input voltage range and termination do not affect load-side performance.

Q: What does "Hockey Puck" versus "Module" packaging mean?

A: These refer to different physical form factors. Hockey Puck is a compact cylindrical or disc-shaped package, while Module refers to a rectangular or flat package design. The choice depends on available mounting space and mechanical constraints in the application.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both CD2425W3V and ASR-SID240D25ZL are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both are active products with current manufacturer support.
