CD4850W4VR Equivalent & Substitute Parts

Part Overview

The CD4850W4VR is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual relay 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 48–660VAC. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this specific relay configuration and electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850W4VR is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2 dual relay arrangement
• Electrical Ratings: Input voltage 4–32VDC, load voltage 48–660VAC, load current 50A
• Output Type: AC switching capability
• Package and Mounting: Hockey puck form factor with chassis mount configuration
• Termination: Screw terminal interface

Parts meeting all these criteria are classified as direct substitutes. The CD4850W4VR has been superseded within the Evolution Dual series by active production alternatives that maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CC4850W4VRH and CD4850W2VR are active production parts within the Evolution Dual series and provide full electrical and mechanical compatibility with the obsolete CD4850W4VR.

CC4850W4VRH is classified as a direct substitute, maintaining identical part number structure and specifications. This part carries RoHS Compliant certification and is currently in active production status.

CD4850W2VR is the manufacturer-recommended alternative, also in active production with RoHS Compliant certification. This part shares the same base product number (CD4850) and identical electrical and mechanical parameters.

Selection between these two active alternatives should be based on availability and supply chain logistics, as both meet all specified electrical and mechanical requirements for direct replacement in existing applications.

Frequently Asked Questions (FAQ)

Q: Can CC4850W4VRH be used as a direct replacement for CD4850W4VR?

A: Yes. CC4850W4VRH maintains identical electrical ratings (4–32VDC input, 48–660VAC output, 50A load current), circuit configuration (SPST-NO x 2), package type (hockey puck), and termination style (screw terminal). The part is in active production status.

Q: What is the difference between CC4850W4VRH and CD4850W2VR?

A: Both parts are active production alternatives with identical electrical and mechanical specifications. They differ in part number designation within the Evolution Dual series. CD4850W2VR is the manufacturer-recommended option. Both are RoHS Compliant and suitable for direct substitution.

Q: Are there any compliance differences between the obsolete part and its substitutes?

A: The obsolete CD4850W4VR does not specify RoHS status. Both active substitutes (CC4850W4VRH and CD4850W2VR) are RoHS Compliant. All three parts share identical ECCN (EAR99) and HTSUS (8536.41.0060) classifications.

Q: Will the hockey puck package fit existing mounting locations?

A: Yes. All three parts use identical hockey puck form factor with chassis mount configuration and screw terminal termination. Physical and electrical interfaces are equivalent.

Q: What inventory status should be considered for procurement?

A: CD4850W4VR (obsolete) has 813 units in stock. CC4850W4VRH (active) has 727 units available. CD4850W2VR (active) has 875 units available. For new designs or long-term supply assurance, active production parts are recommended.
