CC4850W4VR Equivalent & Substitute Parts

Part Overview

The CC4850W4VR is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual-channel device 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 48–660V AC. The part is currently classified as obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC4850W4VR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 channels
• Load current rating: 50 A
• Input voltage range: 4–32VDC
• Output voltage range: 48–660V
• Package type: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal

Substitute parts must maintain identical electrical specifications and mechanical form factor. Product status (active vs. obsolete) and compliance certifications (RoHS, REACH) are secondary considerations that support long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both CC4850W4V and CD4850W2VR meet the core electrical and mechanical requirements for direct substitution of the obsolete CC4850W4VR. Selection between these two active alternatives should be based on the following factors:

CC4850W4V is the manufacturer-recommended substitute, maintaining the same base product series (CC4850) and offering RoHS compliance. This part includes zero-cross switching capability in addition to standard AC output functionality, which may provide enhanced performance in certain applications.

CD4850W2VR is an alternative from the Evolution Dual series with identical electrical ratings and mechanical form factor. This part also carries RoHS compliance and maintains compatibility with the original circuit requirements.

Both substitutes are currently in active production status, ensuring supply chain continuity and regulatory compliance for new designs and field replacements.

Frequently Asked Questions (FAQ)

Q: Can CC4850W4V and CD4850W2VR be used interchangeably with CC4850W4VR?

A: Yes. Both substitute parts maintain identical electrical specifications (50A load current, 4–32VDC input, 48–660V output) and mechanical form factor (hockey puck package, chassis mount, screw terminals). The circuit configuration (SPST-NO x 2) is identical across all three parts.

Q: What is the difference between CC4850W4V and CD4850W2VR?

A: The primary difference is the base product number (CC4850 vs. CD4850) and manufacturer designation. CC4850W4V includes zero-cross switching capability. Both parts are electrically and mechanically equivalent for the specified application parameters.

Q: Why is the original CC4850W4VR classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. Active substitutes (CC4850W4V and CD4850W2VR) are available to support continued system operation and new installations.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CC4850W4V and CD4850W2VR carry RoHS Compliant certification, meeting current regulatory requirements for electronic components.

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

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