Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWA4825S is based on electrical and mechanical parameter equivalence within the CW48 series. The substitute part must maintain identical specifications across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Input voltage range: 90 ~ 280VAC
• Load voltage range: 48 V ~ 660 V
• Load current rating: 25 A
• Termination style: Screw Terminal
• Package form factor: Hockey Puck
• Mounting type: Chassis Mount

The CWA4825P meets all these requirements and is classified as an active product within the same series, making it a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CWA4825P is the direct substitute for the obsolete CWA4825S. Both components share identical electrical ratings and mechanical specifications within the CW48 series. The CWA4825P carries active product status, ensuring ongoing availability and supply chain continuity. The substitute part meets ROHS3 compliance requirements and is REACH Affected, reflecting current regulatory standards for electronic components. Selection of the CWA4825P eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the CWA4825P be used as a direct replacement for the CWA4825S?

A: Yes. Both parts are electrically and mechanically identical. They share the same input voltage range (90-280VAC), load voltage range (48-660V), current rating (25A), circuit configuration (SPST-NO), output type (AC zero-cross), termination style (screw terminal), and package form factor (hockey puck). The CWA4825P is the active equivalent.

Q: What is the difference between the CWA4825S and CWA4825P?

A: The primary difference is product status. The CWA4825S is obsolete, while the CWA4825P is active. The CWA4825P also carries ROHS3 compliance certification and is REACH Affected, whereas the CWA4825S is REACH Unaffected. All functional and electrical parameters are identical.

Q: Are there packaging differences between these parts?

A: The CWA4825S is supplied in standard packaging, while the CWA4825P is supplied in bulk packaging. Both maintain the hockey puck form factor and screw terminal configuration. Packaging differences do not affect electrical or mechanical compatibility.

Q: Does the CWA4825P meet current regulatory requirements?

A: Yes. The CWA4825P is ROHS3 compliant and REACH Affected, meeting current electronic component regulatory standards. The obsolete CWA4825S does not carry these certifications.

Q: Can I use the CWA4825P in applications originally designed for the CWA4825S?

A: Yes. The CWA4825P maintains full compatibility with all applications designed for the CWA4825S. Electrical ratings, switching characteristics, and physical dimensions are identical.
