CD4850D1V Equivalent & Substitute Parts

Part Overview

The CD4850D1V is a solid-state relay (SSR) manufactured by Sensata Technologies, 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 load voltage range of 48–660V AC with zero-cross switching capability.

The CD4850D1V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850D1V is determined by the following critical parameters:

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

The substitute part CD4850W2V maintains all critical electrical and mechanical parameters required for direct substitution. The input voltage range differs (4–32VDC versus 4–15VDC), which represents an expanded operating window and does not restrict compatibility with existing 4–15VDC control circuits.

Parameter Comparison

Engineering Selection Recommendations

The CD4850W2V is the direct substitute for the CD4850D1V. Both components share identical electrical load specifications (50A, 48–660V AC) and circuit configuration (dual SPST-NO channels with zero-cross switching). The CD4850W2V is currently in active production status, whereas the CD4850D1V is obsolete.

The CD4850W2V features an expanded input voltage range (4–32VDC) compared to the CD4850D1V (4–15VDC). This expanded range is compatible with all control circuits designed for the original part and introduces no compatibility restrictions.

The CD4850W2V carries ROHS3 compliance certification, supporting regulatory requirements for new designs and applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can the CD4850W2V directly replace the CD4850D1V in existing applications?

A: Yes. The CD4850W2V maintains identical load current (50A), load voltage range (48–660V AC), circuit configuration (dual SPST-NO), output type (AC zero-cross), package type (Hockey Puck), mounting type (Chassis Mount), and termination style (Screw Terminal). The expanded input voltage range of the CD4850W2V (4–32VDC) is backward-compatible with control circuits designed for 4–15VDC operation.

Q: What is the significance of the input voltage range difference?

A: The CD4850W2V accepts input voltages from 4–32VDC, whereas the CD4850D1V accepts 4–15VDC. The CD4850W2V's expanded range does not restrict its use in applications limited to 4–15VDC. Existing control circuits require no modification.

Q: Are there mechanical or dimensional differences between these parts?

A: Both parts use the Hockey Puck package with Chassis Mount configuration and Screw Terminal termination. No mechanical or dimensional modifications are required for substitution.

Q: What is the inventory status of these parts?

A: The CD4850D1V is obsolete with 802 units available. The CD4850W2V is in active production with 1082 units available.

Q: Does the CD4850W2V meet current regulatory standards?

A: The CD4850W2V is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.
