CD4850D3VH Equivalent & Substitute Parts

Part Overview

The CD4850D3VH 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 4–15VDC and output voltage range of 48–660VAC, featuring zero-cross switching for AC loads.

The CD4850D3VH is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850D3VH is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC, Zero Cross
• Load voltage range: 48 V ~ 660 V
• Load current rating: 50 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

Substitute parts must maintain identical electrical performance characteristics and physical form factor. Input voltage range variations are permitted only when the substitute part's input range encompasses or exceeds the original specification. Product status (active vs. obsolete) and compliance certifications are secondary considerations that inform selection priority but do not disqualify functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (CC4850D3VH, CD4850W3VH, and CD4850D1VH) satisfy the core electrical and mechanical requirements for direct substitution with the obsolete CD4850D3VH.

CC4850D3VH and CD4850D1VH are functionally identical to the main part, with matching input voltage specifications (4–15VDC) and active product status. Both carry RoHS compliance certification.

CD4850W3VH provides an extended input voltage range (4–32VDC), which encompasses the original specification and offers broader operational flexibility. This part is also active and RoHS compliant.

For applications requiring immediate availability and compliance documentation, any of the three active substitutes are suitable. The choice between them depends on whether the extended input voltage range of CD4850W3VH provides operational advantage for the specific application.

Frequently Asked Questions (FAQ)

Q: Can CC4850D3VH replace CD4850D3VH directly?

A: Yes. CC4850D3VH maintains identical electrical specifications (50A, 48–660V output, 4–15VDC input) and physical form factor (hockey puck, screw terminal, chassis mount). The manufacturer designation change from Sensata-Crydom to Sensata Technologies reflects corporate consolidation within the same organization.

Q: What is the difference between CD4850W3VH and CD4850D1VH?

A: CD4850W3VH has an extended input voltage range of 4–32VDC, compared to 4–15VDC for CD4850D1VH. All other electrical and mechanical parameters are identical. Selection depends on whether the application requires the wider input voltage tolerance.

Q: Are all substitutes RoHS compliant?

A: Yes. CC4850D3VH, CD4850W3VH, and CD4850D1VH are all RoHS compliant. The main part (CD4850D3VH) does not specify RoHS status in available documentation.

Q: Does packaging type affect substitution?

A: CD4850W3VH is supplied in bulk packaging, while CC4850D3VH and CD4850D1VH do not specify packaging type. All three parts use the same hockey puck case and screw terminal configuration, ensuring mechanical compatibility regardless of packaging format.

Q: Why is the CD4850D3VH obsolete?

A: Product obsolescence is determined by the manufacturer. Active substitutes with identical or superior specifications are available from the same manufacturer family.
