CD4850D3V Equivalent & Substitute Parts

Part Overview

The CD4850D3V is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay 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 CD4850D3V is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4850D3V is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC with zero-cross switching
• Load voltage range: 48–660V
• Load current rating: 50A
• Package type: Hockey puck
• Mounting: Chassis mount
• Termination: Screw terminal

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in input voltage range, product status, and RoHS compliance are noted but do not disqualify substitution when the load-side parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CC4850D3V, CD4850W3V, and CD4850D2V—maintain functional equivalence to the CD4850D3V across load-side electrical parameters and mechanical form factor. Selection among these alternatives should be based on the following criteria:

CC4850D3V is an active product with RoHS compliance and identical input voltage specification (4–15VDC) to the original part, making it the direct functional replacement.

CD4850W3V is an active product with ROHS3 compliance and an extended input voltage range (4–32VDC), providing greater flexibility for control circuits operating at higher input voltages while maintaining all load-side specifications.

CD4850D2V is an active product with RoHS compliance and input voltage specification matching the original (4–15VDC), designated as manufacturer-recommended and suitable for direct substitution.

All three parts are currently in stock and available as new original components.

Frequently Asked Questions (FAQ)

Q: Can CC4850D3V directly replace CD4850D3V? A: Yes. CC4850D3V maintains identical circuit configuration, output type, load voltage range, load current rating, package type, and termination style. The primary difference is product status (active vs. obsolete) and RoHS compliance certification.

Q: What is the difference between CD4850W3V and the other substitutes? A: CD4850W3V has an extended input voltage range of 4–32VDC compared to 4–15VDC for CD4850D3V, CC4850D3V, and CD4850D2V. All other electrical and mechanical parameters remain equivalent. This extended range allows operation with higher control voltages.

Q: Are all substitutes available in the same package? A: Yes. All substitute parts use the hockey puck package with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility with existing designs.

Q: Does RoHS compliance affect substitution suitability? A: RoHS compliance is a regulatory and environmental certification that does not affect electrical or mechanical substitution. All active substitutes carry RoHS or ROHS3 compliance, meeting current regulatory requirements.

Q: Which substitute should be selected for new designs? A: For new designs requiring this functional specification, any of the three active substitutes is suitable. CD4850W3V offers the broadest input voltage flexibility, while CC4850D3V and CD4850D2V provide direct parameter matching to the original part.
