CC2450W3VR Equivalent & Substitute Parts

Part Overview

The CC2450W3VR is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual channels 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 listed as obsolete, necessitating identification of functionally equivalent active alternatives to maintain supply chain continuity for applications requiring this relay specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CC2450W3VR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 channels
• Output type: AC
• Input voltage range: 4–32VDC
• Load voltage range: 24–280VAC
• Load current rating: 50A
• Package type: Hockey Puck
• Mounting: Chassis Mount
• Termination: Screw Terminal
• Manufacturer: Sensata-Crydom Evolution Dual series

The identified substitutes CC2450W2VR and CC2450W4UR meet all electrical and mechanical parameters specified for the CC2450W3VR. Both alternatives are active products with current manufacturing status, distinguishing them from the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both CC2450W2VR and CC2450W4UR are direct functional equivalents to the CC2450W3VR. Selection between these two active alternatives should be based on:

• Availability: CC2450W2VR (1073 pcs in stock) and CC2450W4UR (933 pcs in stock)
• Compliance: Both substitutes are RoHS Compliant, providing regulatory advantage over the obsolete main part
• Supply continuity: Both parts are manufactured by Sensata-Crydom in the active Evolution Dual series

No technical performance differentiation exists between the three parts based on provided specifications. The choice between CC2450W2VR and CC2450W4UR is determined by procurement requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CC2450W2VR and CC2450W4UR be used interchangeably with CC2450W3VR?

A: Yes. Both substitutes maintain identical electrical ratings (50A at 24–280VAC output, 4–32VDC input), circuit configuration (dual SPST-NO channels), and mechanical specifications (hockey puck package, screw terminals, chassis mount). No circuit redesign or application modification is required.

Q: Why is the CC2450W3VR listed as obsolete?

A: Product status reflects manufacturing discontinuation by Sensata-Crydom. The CC2450W2VR and CC2450W4UR remain in active production and provide equivalent functionality.

Q: Are there differences in the hockey puck package between these parts?

A: No. All three parts use identical hockey puck packaging with screw terminal termination and chassis mount configuration.

Q: What is the significance of RoHS compliance for the substitute parts?

A: CC2450W2VR and CC2450W4UR are RoHS Compliant, meeting Restriction of Hazardous Substances regulations. This provides regulatory compliance advantage for applications subject to RoHS requirements.

Q: Can I mix CC2450W2VR and CC2450W4UR in the same application?

A: Yes. Both parts meet identical electrical and mechanical specifications and can be used together in multi-relay applications without compatibility issues.
