CWA2425S Equivalent & Substitute Parts

Part Overview

The CWA2425S is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) with a hockey puck form factor. This component is designed for AC switching applications with a 25A load capacity across a 24V to 280V range, controlled by a 90V to 280VAC input signal. The CWA2425S is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWA2425S is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Input voltage range: 90 ~ 280VAC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 25 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package form factor: Hockey Puck
• Series family: CW24

The CWA2425P is identified as the manufacturer-recommended substitute. Both components share identical electrical specifications and mechanical form factors, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The CWA2425P is the direct equivalent substitute for the CWA2425S. Both components are manufactured by Sensata-Crydom within the CW24 series and maintain identical electrical and mechanical specifications. The CWA2425P is currently in active production status, whereas the CWA2425S is obsolete.

The CWA2425P carries RoHS Compliant certification, providing regulatory advantage for new designs and systems requiring environmental compliance documentation. Both components share identical ECCN (EAR99) and HTSUS (8536.49.0080) classifications.

Selection of the CWA2425P is appropriate for direct replacement applications where the CWA2425S is no longer available, as well as for new system designs requiring a 25A, 24-280V AC solid-state relay with SPST-NO switching and zero-cross output control.

Frequently Asked Questions (FAQ)

Q: Can the CWA2425P directly replace the CWA2425S in existing applications?

A: Yes. Both components share identical electrical ratings (25A load current, 90-280VAC input, 24-280V load voltage), circuit configuration (SPST-NO), output type (AC, Zero Cross), mounting type (Chassis Mount), termination style (Screw Terminal), and package form factor (Hockey Puck). Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between the CWA2425S and CWA2425P?

A: The CWA2425S is obsolete, while the CWA2425P is in active production. The CWA2425P also carries RoHS Compliant certification. All functional and electrical parameters are identical.

Q: Are there any packaging differences between these parts?

A: The CWA2425S packaging designation is listed as "-" (unspecified), while the CWA2425P is supplied in Bulk packaging. Both components use the same Hockey Puck form factor and screw terminal configuration.

Q: What does "Zero Cross" output type mean for this SSR?

A: Zero Cross output type indicates that the solid-state relay switches the AC load at the zero-crossing point of the AC waveform. This reduces electromagnetic interference and is standard for AC switching applications in the CW24 series.

Q: Is the CWA2425P suitable for new designs?

A: Yes. The CWA2425P is in active production status and carries RoHS Compliant certification, making it appropriate for new system designs requiring a 25A, AC solid-state relay with the specified electrical and mechanical characteristics.
