Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWA4810S is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Output Type: AC switching with zero-cross functionality required
• Voltage Ratings: Input range 90–280VAC and load range 48–660V must be matched
• Load Current: 10A rating must be preserved
• Mounting and Termination: Chassis mount with screw terminal configuration
• Package Form Factor: Hockey puck mechanical envelope

The CWA4810P qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status: CWA4810P is active and available, whereas CWA4810S is obsolete.
