CD4850W4VRH Equivalent & Substitute Parts

Part Overview

The CD4850W4VRH is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual relay module 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 listed as obsolete, making identification of equivalent and substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4850W4VRH is determined by strict equivalence across the following critical parameters:

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

All identified substitute parts maintain identical electrical and mechanical specifications across these parameters. Substitution is valid based on matching these core attributes without additional testing or verification requirements.

Parameter Comparison

Engineering Selection Recommendations

CC4850W4VRH is the direct equivalent substitute, maintaining identical part number structure and specifications while offering active product status and RoHS compliance. This part is the primary replacement option for the obsolete CD4850W4VRH.

CD4850W1VRH and CD4850W3VRH are manufacturer-recommended alternatives within the Evolution Dual series, both with active product status and RoHS compliance. These parts share the same base product number (CD4850 and CD4850 respectively) and maintain full electrical and mechanical compatibility with the original specification.

All three substitute parts are suitable for direct replacement based on matching electrical ratings, circuit configuration, and physical form factor. Selection among these options may be based on availability, lead time, or procurement preference, as all meet the specified technical requirements.

Frequently Asked Questions (FAQ)

Q: Can CC4850W4VRH be used as a direct replacement for CD4850W4VRH?

A: Yes. CC4850W4VRH maintains identical electrical specifications (50A, 4–32VDC input, 48–660V output), circuit configuration (SPST-NO x 2), and physical package (hockey puck, screw terminal, chassis mount). The part is currently in active production status with RoHS compliance.

Q: What is the difference between CD4850W1VRH and CD4850W3VRH?

A: Both parts are functionally equivalent to CD4850W4VRH across all specified electrical and mechanical parameters. The differences in part number suffix (W1 vs. W3) reflect internal design variations within the Evolution Dual series, but do not affect compatibility or performance in applications requiring the specified ratings.

Q: Why is the original CD4850W4VRH listed as obsolete?

A: Product obsolescence indicates the part is no longer manufactured. The substitute parts listed (CC4850W4VRH, CD4850W1VRH, CD4850W3VRH) are active alternatives that fulfill the same functional requirements and are available for procurement.

Q: Are all substitute parts RoHS compliant?

A: Yes. CC4850W4VRH, CD4850W1VRH, and CD4850W3VRH are all RoHS compliant. The original CD4850W4VRH RoHS status was not specified in available documentation.

Q: Can these relays be used interchangeably in existing installations?

A: Yes, provided the installation uses screw terminal connections and chassis mount configuration. All substitute parts maintain identical input/output voltage ranges, load current rating, and circuit topology (SPST-NO x 2 configuration).
