CWA4850E Equivalent & Substitute Parts

Part Overview

The CWA4850E is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (1 Form A) with hockey puck form factor. This component is designed for AC load switching applications requiring 50A capacity across a 48V to 660V load voltage range, with 18-36VAC input control voltage. The product maintains Active status with full RoHS compliance. Substitute parts are identified when electrical specifications, mechanical form factor, and termination style align with the original component requirements.

• Output Type: AC, Zero Cross
• Voltage - Input: 18 ~ 36VAC
• Voltage - Load: 48 V ~ 660 V
• Load Current: 50 A
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal
• Package / Case: Hockey Puck
• RoHS Compliance: Required

The substitute part 84137122N (Crouzet, Series GN) meets all specified electrical and mechanical parameters, enabling direct functional equivalence in applications requiring these exact specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4850E and 84137122N maintain Active product status with full RoHS compliance, ensuring regulatory alignment for current applications. The CWA4850E carries ECCN EAR99 classification, while the substitute 84137122N carries the same ECCN designation. Both components are classified as REACH Unaffected or equivalent, supporting use in regulated markets. Selection between these parts should be based on availability, lead time, and supply chain requirements, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can 84137122N replace CWA4850E in existing designs? A: Yes. Both parts share identical electrical specifications (50A at 48-660V load, 18-36VAC input), circuit configuration (SPST-NO), output type (AC, Zero Cross), termination style (Screw Terminal), and package form factor (Hockey Puck). No design modification is required.

Q: Are there differences in packaging between these parts? A: The CWA4850E is supplied in Bulk packaging, while 84137122N is supplied in Box packaging. Both use the same Hockey Puck mechanical form factor and screw terminal interface.

Q: Do both parts meet RoHS requirements? A: Yes. Both CWA4850E and 84137122N are RoHS Compliant, meeting regulatory requirements for restricted substances.

Q: What determines substitution eligibility for this SSR category? A: Substitution is valid when the following parameters match: circuit configuration (SPST-NO), output type (AC, Zero Cross), input voltage range (18-36VAC), load voltage range (48-660V), load current (50A), mounting type (Chassis Mount), termination style (Screw Terminal), and package form factor (Hockey Puck).

Q: Are there any compliance differences between these parts? A: Both parts carry ECCN EAR99 classification and maintain Active product status. Moisture sensitivity levels differ (CWA4850E: Not Applicable; 84137122N: MSL 1), but this does not affect substitution eligibility for this application category.
