CWA2450S Equivalent & Substitute Parts

Part Overview

The CWA2450S is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 50A load current and input voltage range of 90–280VAC. This component features a hockey puck form factor with screw terminal connections and zero-cross AC output switching. The CWA2450S is classified as obsolete, necessitating identification of active equivalent parts for continued system support and procurement.

Substitute Part Grouping Explanation

Substitution of the CWA2450S is determined by electrical and mechanical parameter equivalence within the CW24 series. The primary substitute, CWA2450P, maintains identical specifications across all critical parameters: SPST-NO circuit configuration, 50A load current rating, 90–280VAC input voltage range, 24–280V load voltage range, AC zero-cross output switching, screw terminal termination, and hockey puck package form factor. The CWA2450P differs only in product status (Active) and packaging designation (Bulk), making it a direct functional equivalent. Both parts share the same base product number (CWA2450) and series designation (CW24), confirming their interchangeability for applications requiring these electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CWA2450P is the direct substitute for the obsolete CWA2450S. Both components are manufactured by Sensata-Crydom and share identical electrical ratings and mechanical specifications. The CWA2450P maintains active product status, ensuring ongoing availability and manufacturer support. The CWA2450P carries RoHS Compliant certification, providing compliance advantage for applications subject to RoHS requirements. Both parts are classified under ECCN EAR99 and HTSUS 8536.49.0080, confirming regulatory equivalence. Selection of the CWA2450P eliminates obsolescence risk while maintaining full functional compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the CWA2450P directly replace the CWA2450S in existing applications?

A: Yes. The CWA2450P is electrically and mechanically equivalent to the CWA2450S. Both components feature identical circuit configuration (SPST-NO), load current rating (50A), input voltage range (90–280VAC), load voltage range (24–280V), output type (AC, zero-cross), termination style (screw terminal), and package form factor (hockey puck). Direct substitution is supported without circuit modification.

Q: What is the primary difference between the CWA2450S and CWA2450P?

A: The CWA2450S is classified as obsolete, while the CWA2450P maintains active product status. The CWA2450P also carries RoHS Compliant certification. All electrical and mechanical parameters remain identical between the two parts.

Q: Are there any packaging considerations when substituting the CWA2450P for the CWA2450S?

A: Both parts utilize the hockey puck package form factor with screw terminal connections. Packaging designation differs (the CWA2450S uses standard packaging while the CWA2450P uses bulk packaging), but the physical dimensions and mounting characteristics remain unchanged, ensuring compatibility with existing mechanical assemblies.

Q: What certifications apply to the CWA2450P?

A: The CWA2450P is RoHS Compliant and classified under ECCN EAR99 and HTSUS 8536.49.0080, matching the regulatory classification of the CWA2450S.

Q: Why is the CWA2450S classified as obsolete?

A: The CWA2450S has reached end-of-life status. The CWA2450P serves as the active equivalent for continued procurement and system support.
