Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWA4850S is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 50 A
• Load voltage range: 48 V ~ 660 V AC
• Input voltage range: 90 ~ 280 VAC
• Output switching type: AC, Zero Cross
• Termination style: Screw Terminal
• Package form factor: Hockey Puck
• Mounting type: Chassis Mount

The CWA4850P qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above. The primary distinction is product status: CWA4850P is active and available, whereas CWA4850S is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The CWA4850P is the direct equivalent for CWA4850S replacement. Both components share identical electrical ratings and mechanical specifications. Selection of CWA4850P is supported by its active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with current manufacturing standards. The CWA4850P is available in bulk packaging and maintains full compatibility with existing CWA4850S installations.

Frequently Asked Questions (FAQ)

Q: Can CWA4850P directly replace CWA4850S in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 50A load current, 48V–660V AC load voltage, 90–280VAC input, SPST-NO configuration, zero-cross switching, screw terminal termination, and hockey puck form factor.

Q: What is the primary reason to transition from CWA4850S to CWA4850P?

A: CWA4850S is obsolete. CWA4850P is an active product with confirmed availability and current manufacturing support.

Q: Are there packaging differences between CWA4850S and CWA4850P?

A: CWA4850S packaging is listed as unspecified. CWA4850P is supplied in bulk packaging. Both use identical hockey puck case form factors and screw terminal connections.

Q: What compliance certifications apply to CWA4850P?

A: CWA4850P is ROHS3 compliant and REACH affected. CWA4850S is REACH unaffected with no RoHS status specified.

Q: Are there inventory considerations for component selection?

A: CWA4850S inventory is 1127 pieces. CWA4850P inventory is 1161 pieces. Both are available as new original stock.
