CD4850W3VR Equivalent & Substitute Parts

Part Overview

The CD4850W3VR 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 at 48V to 660V AC output, with 4-32VDC input control voltage. The part is currently listed as obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850W3VR is determined by strict equivalence across the following critical parameters:

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

The identified substitute parts maintain identical electrical specifications and mechanical form factors, ensuring direct functional replacement without circuit redesign. Both substitute parts are manufactured by Sensata-Crydom within the Evolution Dual series, confirming design compatibility and performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both CC4850W3V and CD4850W2VR are qualified substitutes for the obsolete CD4850W3VR based on electrical and mechanical parameter equivalence. Selection between the two active alternatives should be based on the following criteria:

CC4850W3V is designated as the manufacturer-recommended primary substitute. This part carries RoHS Compliant certification and includes zero-cross switching functionality in its output specification, providing enhanced control characteristics for AC load applications. The part is available in bulk packaging with 1153 units in stock.

CD4850W2VR serves as a secondary substitute option, maintaining identical core electrical ratings and mechanical specifications. This part is also RoHS Compliant and available with 875 units in stock. The absence of zero-cross specification in the output type may be relevant for applications where precise switching timing relative to the AC waveform is not a design requirement.

Both parts comply with ECCN EAR99 and HTSUS 8536.41.0060 classifications, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can CC4850W3V and CD4850W2VR be used interchangeably with CD4850W3VR?

A: Both parts are functionally equivalent substitutes. They maintain identical load current (50A), voltage ratings (48-660V AC load, 4-32VDC input), circuit configuration (SPST-NO x 2), and mechanical form factor (hockey puck, chassis mount, screw terminal). Direct replacement is supported without circuit modification.

Q: What is the difference between CC4850W3V and CD4850W2VR?

A: The primary difference is the output type specification. CC4850W3V includes zero-cross switching capability, while CD4850W2VR specifies standard AC output. Both parts are electrically and mechanically equivalent for the core 50A, 48-660V AC application. Selection depends on whether zero-cross switching functionality is required by the application.

Q: Why is the original CD4850W3VR listed as obsolete?

A: The CD4850W3VR has been discontinued by the manufacturer. Active equivalent models (CC4850W3V and CD4850W2VR) are available to fulfill the same functional requirements in new designs and field replacements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CC4850W3V and CD4850W2VR carry RoHS Compliant certification. The original CD4850W3VR RoHS status was not specified in the available documentation.

Q: What packaging options are available for the substitute parts?

A: CC4850W3V is supplied in bulk packaging. CD4850W2VR packaging specification is not detailed in the available data. Contact the supplier for specific packaging requirements or custom configurations.

Q: Are there any differences in termination or mounting between the main part and substitutes?

A: No. All three parts (CD4850W3VR, CC4850W3V, and CD4850W2VR) use identical screw terminal termination and chassis mount configuration in the hockey puck package form factor.
