CD2450W3VR Equivalent & Substitute Parts

Part Overview

The CD2450W3VR is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual output capability in a hockey puck package. This component is rated for 50A load current with input voltage range of 4–32VDC and output voltage range of 24–280VAC. The part is currently obsolete, necessitating identification of functionally equivalent active alternatives to maintain system continuity and procurement availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD2450W3VR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Load current rating: 50 A
• Input voltage range: 4–32VDC
• Output voltage range: 24–280VAC
• Output type: AC (with or without zero-cross capability)
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

All identified substitute parts maintain these electrical and mechanical specifications. Variations in product status (Active vs. Obsolete), RoHS compliance level, and zero-cross functionality do not affect core substitutability for applications requiring the specified load and voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (CC2450W3V, CD2450W1VR, CD2450W2VR) are functionally equivalent to the CD2450W3VR and maintain active product status. Selection among these alternatives should be based on the following criteria:

CC2450W3V is the manufacturer-recommended primary substitute, offering ROHS3 compliance and zero-cross output functionality. This part is manufactured by Sensata Technologies and provides the highest level of regulatory compliance.

CD2450W1VR and CD2450W2VR are alternative active substitutes manufactured by Sensata-Crydom and Sensata Technologies respectively, both offering RoHS compliance. These parts are electrically identical to the original CD2450W3VR with the exception of zero-cross capability in the CC2450W3V variant.

All substitute parts share identical electrical ratings, mechanical mounting, and termination specifications with the obsolete original part, ensuring direct functional replacement in existing applications.

Frequently Asked Questions (FAQ)

Q: Can CC2450W3V replace CD2450W3VR in all applications?

A: Yes. CC2450W3V maintains identical electrical specifications (50A, 4–32VDC input, 24–280VAC output) and mechanical form factor (hockey puck, screw terminal, chassis mount). The addition of zero-cross functionality in CC2450W3V does not prevent substitution and may provide enhanced performance in certain AC switching applications.

Q: What is the difference between the substitute parts?

A: The three substitute parts are electrically equivalent across all critical parameters. The primary distinction is that CC2450W3V includes zero-cross output capability, while CD2450W1VR and CD2450W2VR provide standard AC output. Manufacturer and RoHS compliance levels also differ, with CC2450W3V offering ROHS3 compliance.

Q: Are all substitute parts in active production?

A: Yes. All three substitute parts (CC2450W3V, CD2450W1VR, CD2450W2VR) maintain active product status, ensuring ongoing availability and supply chain continuity.

Q: Does the hockey puck package remain the same across all substitutes?

A: Yes. All substitute parts retain the hockey puck package configuration with screw terminal termination and chassis mount design, ensuring mechanical compatibility with existing installations.

Q: Are there any compliance differences between substitutes?

A: CC2450W3V is ROHS3 compliant, while CD2450W1VR and CD2450W2VR are RoHS compliant. Both compliance levels are acceptable for most applications; selection should align with specific system or regional regulatory requirements.
