Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA2490S is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC with zero-cross switching
• Input Voltage Range: 90–280VAC
• Load Voltage Range: 24–280V
• Load Current Rating: 90A
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal
• Package Form Factor: Hockey Puck

The CWA2490P qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: CWA2490P is active and available, whereas CWA2490S is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The CWA2490P is the designated substitute for the obsolete CWA2490S. Both components share identical electrical ratings and mechanical specifications within the CW24 series. The CWA2490P maintains active product status and carries RoHS compliance certification, making it the appropriate selection for new procurement and system replacements. No functional or performance differences exist between these parts; selection is driven by availability and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can CWA2490P be used as a direct replacement for CWA2490S in existing applications?

A: Yes. The CWA2490P is electrically and mechanically equivalent to the CWA2490S across all specified parameters: 90A load current, 90–280VAC input voltage, 24–280V load voltage, SPST-NO circuit configuration, AC zero-cross output, screw terminal termination, and hockey puck form factor. No circuit modifications or mechanical adjustments are required.

Q: What is the primary reason for substitution?

A: The CWA2490S is obsolete and no longer manufactured. The CWA2490P is the active equivalent from the same manufacturer and series, ensuring continued availability and supply chain continuity.

Q: Are there compliance differences between CWA2490S and CWA2490P?

A: The CWA2490P is certified RoHS Compliant. RoHS status for the CWA2490S is not specified in available documentation. Both components share identical ECCN (EAR99) and HTSUS (8536.49.0080) classifications.

Q: Does packaging differ between these parts?

A: The CWA2490S is supplied with dash packaging notation, while CWA2490P is supplied in bulk packaging. Both maintain the same hockey puck form factor and screw terminal configuration. Packaging differences do not affect electrical or mechanical compatibility.

Q: Are input and output voltage ranges identical?

A: Yes. Both CWA2490S and CWA2490P operate with 90–280VAC input voltage and 24–280V load voltage specifications. Load current capacity is 90A for both parts.
