CD4850W4VH Equivalent & Substitute Parts

Part Overview

The CD4850W4VH is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual Form A circuits. This component is designed for AC load switching applications with zero-cross detection capability. The device operates with a 4–32VDC input signal and supports load voltages ranging from 48V to 660V at a maximum load current of 50A. The product maintains Active status and is RoHS Compliant. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific application requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850W4VH is determined by the following critical parameters:

• Circuit configuration (SPST-NO with dual Form A circuits)
• Load current rating (50A minimum)
• Output type (AC with zero-cross detection)
• Mounting type (Chassis Mount)
• Termination style (Screw Terminal)
• Regulatory compliance (RoHS status)

The substitute part ASR-SID480D50ZL-SP meets the core functional requirements of dual SPST-NO circuits, 50A load current capacity, AC output with zero-cross operation, chassis mount configuration, and screw terminal termination. Both parts maintain equivalent regulatory compliance classifications. The primary distinction lies in the input voltage range (4–15VDC for the substitute versus 4–32VDC for the main part) and the maximum load voltage specification (24–530V for the substitute versus 48–660V for the main part), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection between the CD4850W4VH and ASR-SID480D50ZL-SP must be based on application-specific voltage requirements. The CD4850W4VH supports input voltages up to 32VDC and load voltages up to 660V, making it suitable for higher-voltage applications. The ASR-SID480D50ZL-SP operates within a narrower input voltage range (4–15VDC maximum) and supports load voltages up to 530V, restricting its use to applications within these specifications.

Both parts maintain Active product status and comply with RoHS regulations (RoHS Compliant and ROHS3 Compliant respectively), ensuring regulatory alignment for current manufacturing standards. The physical package difference (Hockey Puck versus Module) must be evaluated against mechanical integration requirements and available mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SID480D50ZL-SP substitute for the CD4850W4VH in all applications?

A: Substitution is valid only when the application input voltage does not exceed 15VDC and the load voltage does not exceed 530V. Applications requiring higher input or load voltages must use the CD4850W4VH.

Q: What is the significance of the package difference between Hockey Puck and Module?

A: Package type affects mechanical mounting, thermal dissipation characteristics, and physical footprint. The Hockey Puck configuration of the CD4850W4VH and the Module configuration of the ASR-SID480D50ZL-SP are not interchangeable from a mechanical standpoint and require separate mechanical design validation.

Q: Are both parts suitable for new designs?

A: Both parts maintain Active product status, indicating current manufacturing availability and suitability for new designs. Selection should be based on voltage requirements and mechanical constraints specific to the application.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS (Restriction of Hazardous Substances) regulations. ROHS3 represents the current iteration of the standard. Both parts meet contemporary regulatory requirements for hazardous substance restriction.

Q: Are the screw terminal connections identical between both parts?

A: Both parts use screw terminal termination style. Physical compatibility must be verified against the specific connector specifications and pin configurations of each manufacturer, as terminal sizing and pitch may differ.
