CWA4810-10 Equivalent & Substitute Parts

Part Overview

The CWA4810-10 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 a rated load current of 10 A and operates across a load voltage range of 48 V to 660 V. The part is currently in active product status and RoHS compliant.

Equivalent and substitute parts are identified when alternative SSR models share compatible electrical and mechanical characteristics within the allowed parameter ranges for this product category. The CWA4810-10 operates with input voltage specifications of 90 V to 280 VAC and requires a chassis mount configuration with screw terminal termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWA4810-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be AC to ensure compatibility with load switching requirements
• Package / Case: Must be Hockey Puck to ensure mechanical fit in chassis mount applications
• Termination Style: Must be Screw Terminal for connection compatibility
• Mounting Type: Must be Chassis Mount for installation compatibility
• Input Voltage Range: Must overlap or encompass 90 ~ 280 VAC
• Load Voltage Range: Must support the 48 V ~ 660 V operating window
• Load Current Rating: Must be rated for the application's current requirements

The substitute part 84137211N (Crouzet GN series) is identified as a manufacturer-recommended equivalent based on shared mechanical packaging, circuit topology, and termination characteristics. However, differences in load current rating (25 A vs. 10 A) and load voltage range (24 V ~ 280 V vs. 48 V ~ 660 V) must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CWA4810-10 and 84137211N are active products with RoHS compliance certification, making them suitable for applications requiring environmental compliance. The selection between these parts depends on application-specific load voltage and current requirements.

The CWA4810-10 is specified for load voltages up to 660 V with a 10 A current rating. The 84137211N operates within a lower load voltage range (24 V ~ 280 V) but provides a higher current capacity of 25 A. Input voltage compatibility is maintained across both parts within the 90 ~ 260 VAC overlap range.

Selection should be based on whether the application load voltage exceeds 280 V. If load voltage requirements fall within the 24 V ~ 280 V range and higher current capacity is beneficial, the 84137211N may be considered. If load voltage exceeds 280 V, the CWA4810-10 is the required selection.

Frequently Asked Questions (FAQ)

Q: Can the 84137211N replace the CWA4810-10 in all applications?

A: No. The 84137211N has a maximum load voltage rating of 280 V, while the CWA4810-10 supports up to 660 V. Substitution is only valid for applications where the load voltage does not exceed 280 V.

Q: Are both parts mechanically compatible with the same mounting hardware?

A: Yes. Both parts share identical hockey puck packaging and chassis mount configuration with screw terminal termination, ensuring mechanical compatibility in the same installation footprint.

Q: What is the input voltage compatibility between these parts?

A: The CWA4810-10 accepts 90 ~ 280 VAC input, while the 84137211N accepts 90 ~ 260 VAC input. Both parts operate within the 90 ~ 260 VAC overlap range. Applications requiring input voltage between 260 VAC and 280 VAC must use the CWA4810-10.

Q: Do both parts have the same circuit configuration?

A: Yes. Both parts are SPST-NO (1 Form A) AC output relays with identical switching logic and control characteristics.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and active products. The CWA4810-10 carries REACH Unaffected status, while the 84137211N has REACH Unaffected status as well, indicating equivalent environmental compliance.
