Equivalent & Substitute Parts for CWA4810

Part Overview

The CWA4810 is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This component functions as an AC output relay with zero-cross switching capability, designed for chassis mount applications with screw terminal connections. The part is currently in active production status and RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for system compatibility, inventory availability, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Switching: AC output with zero-cross capability
• Load Current Rating: 10 A continuous
• Load Voltage Range: 48 V to 660 V AC
• Control Input Voltage: 90 V to 280 VAC
• Physical Form Factor: Hockey puck package
• Mounting Method: Chassis mount with screw terminals
• Regulatory Compliance: RoHS compliant

Parts meeting all these parameters are classified as direct substitutes. Parts with differing load voltage ranges or input voltage specifications are classified as alternative substitutes with restricted application scope.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (84134101): The Sensata-Crydom part 84134101 maintains identical electrical specifications for load voltage (48 V ~ 660 V) and input voltage (90 ~ 280VAC) as the CWA4810. Both components are manufactured by Sensata-Crydom, carry active product status, and are RoHS compliant. This part is suitable for direct replacement in applications requiring the full 48 V to 660 V load voltage range.

Alternative Substitute (84137001N): The Crouzet part 84137001N operates within a reduced load voltage range (24 V ~ 280 V) and input voltage range (20 ~ 265VAC) compared to the CWA4810. This part is suitable only for applications where the load voltage does not exceed 280 V and the control input voltage remains within the 20 V to 265 VAC specification. The Crouzet component is manufactured by a different supplier, maintains active product status, and is RoHS compliant.

Frequently Asked Questions (FAQ)

Q: Can 84134101 be used as a direct replacement for CWA4810? A: Yes. The 84134101 maintains identical load voltage (48 V ~ 660 V) and input voltage (90 ~ 280VAC) specifications, identical circuit configuration (SPST-NO), identical output type (AC, Zero Cross), identical load current (10 A), and identical physical form factor (hockey puck, chassis mount, screw terminal). Both are RoHS compliant and in active production.

Q: What are the limitations of using 84137001N as a substitute? A: The 84137001N operates within a restricted load voltage range of 24 V to 280 V, compared to the CWA4810's 48 V to 660 V range. The input voltage range is also reduced to 20 V to 265 VAC. This part is suitable only for applications where load voltage does not exceed 280 V. Applications requiring voltages above 280 V must use CWA4810 or 84134101.

Q: Are all substitute parts in the same physical package? A: Yes. All three parts (CWA4810, 84134101, and 84137001N) use the hockey puck package form factor with chassis mount configuration and screw terminal connections, ensuring mechanical compatibility in existing mounting designs.

Q: What is the difference between the CWA4810 and 84134101 series designations? A: The CWA4810 belongs to the CW48 series, while 84134101 belongs to the GN series. Both are manufactured by Sensata-Crydom and share identical electrical and mechanical specifications for the parameters listed in this reference.

Q: Are all parts RoHS compliant? A: Yes. The CWA4810, 84134101, and 84137001N are all RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.
