CWA4890E Equivalent & Substitute Parts

Part Overview

The CWA4890E is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) in a hockey puck package. This component is designed for AC load switching applications with zero-cross detection. The part is currently active in production status with 1090 units in stock. Alternative models may be required due to inventory constraints, application-specific voltage requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The CWA4890E has one identified substitute: the Crouzet 84138153N. Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: Both parts must be SPST-NO (1 Form A) topology
• Output Type: Both must support AC switching with zero-cross detection
• Load Current Rating: Both must support 90 A continuous current
• Package Form Factor: Both must use hockey puck chassis-mount configuration with screw terminals
• Compliance: Both must maintain RoHS compliance status

The 84138153N meets all substitution criteria. However, the input voltage range (20 ~ 260 VAC/DC) and load voltage range (24 V ~ 500 V) differ from the CWA4890E, requiring verification that these parameters are compatible with the target application before substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4890E and 84138153N are active production components with RoHS compliance certification. Selection between these parts should be based on application voltage requirements:

• CWA4890E: Select when input voltage is constrained to 18 ~ 36 VAC and load voltage requirements fall within 48 V ~ 660 V
• 84138153N: Select when input voltage flexibility (20 ~ 260 VAC/DC) is required and load voltage operates within 24 V ~ 500 V

Both components share identical load current capacity (90 A), circuit topology (SPST-NO), output switching characteristics (AC, zero-cross), and physical form factor (hockey puck, chassis mount, screw terminal). Substitution is mechanically and electrically feasible when voltage parameters align with application specifications.

Frequently Asked Questions (FAQ)

Q: Can the 84138153N directly replace the CWA4890E in all applications?

A: Direct substitution is possible only when the application input voltage and load voltage requirements fall within the 84138153N specifications (20 ~ 260 VAC/DC input; 24 V ~ 500 V load). If the original design requires the CWA4890E's 48 V ~ 660 V load voltage range, the 84138153N is not suitable.

Q: What are the key compatibility factors for these SSR relays?

A: The critical compatibility factors are: SPST-NO circuit topology, 90 A load current rating, AC zero-cross output type, hockey puck package form factor, and screw terminal connections. Both parts meet these requirements.

Q: Are there packaging differences between these parts?

A: The CWA4890E is supplied in bulk packaging, while the 84138153N is supplied in box packaging. The physical component form factor (hockey puck, chassis mount) is identical.

Q: Do both parts meet the same compliance standards?

A: Both the CWA4890E and 84138153N are RoHS compliant and classified under ECCN EAR99 with HTSUS code 8536.49.0080.

Q: What is the primary difference between these two SSR models?

A: The primary difference is the voltage operating range. The CWA4890E supports higher load voltages (up to 660 V) with a narrower input voltage window (18 ~ 36 VAC). The 84138153N supports a broader input voltage range (20 ~ 260 VAC/DC) but with a lower maximum load voltage (500 V).
