CWD4825-10 Equivalent & Substitute Parts

Part Overview

The CWD4825-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a rated load current of 25 A and operates across a load voltage range of 48 V to 660 V. The device is actively produced and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CWD4825-10 are qualified based on the following critical parameters that must remain constant or within acceptable ranges:

Mandatory Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Output Type: AC
• Input Voltage Range: 4 ~ 32 VDC
• Load Current Rating: 25 A
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal
• Package / Case: Hockey Puck

Allowable Variation:

• Load Voltage Range: Substitutes must support the minimum load voltage requirement of the application. The CWD4825-10 supports 48 V ~ 660 V; substitutes with lower maximum voltage ratings are acceptable only if the application load voltage does not exceed the substitute's rated range.
• Compliance Status: Active product status is preferred; RoHS compliance must be maintained or upgraded.

Parameter Comparison

Engineering Selection Recommendations

84134310 (Sensata-Crydom): This part is a direct substitute for the CWD4825-10. Both devices are manufactured by Sensata-Crydom and share identical electrical specifications, including the 48 V ~ 660 V load voltage range. Both maintain RoHS3 compliance and active product status. This substitute provides equivalent performance with no derating required.

84137210N (Crouzet): This part is a cross-manufacturer substitute manufactured by Crouzet. It matches all mandatory parameters except for the load voltage range, which is rated 24 V ~ 280 V compared to the CWD4825-10's 48 V ~ 660 V range. This substitute is suitable only for applications where the load voltage does not exceed 280 V. The device maintains RoHS compliance and active product status. Selection of this substitute requires confirmation that the application load voltage falls within the 24 V ~ 280 V range.

Frequently Asked Questions (FAQ)

Q: Can the 84134310 be used as a direct replacement for the CWD4825-10?

A: Yes. The 84134310 is a direct substitute with identical electrical and mechanical specifications. No circuit modifications or derating are required.

Q: Under what conditions can the 84137210N (Crouzet) be substituted?

A: The 84137210N can be substituted only when the application load voltage does not exceed 280 V. The CWD4825-10 supports load voltages up to 660 V; the Crouzet part is limited to 280 V maximum. Verify the application load voltage before selecting this substitute.

Q: Are all substitutes available in the same package configuration?

A: Yes. All listed substitutes are supplied in the hockey puck package with screw terminal connections and chassis mount configuration, matching the CWD4825-10.

Q: Do the substitute parts maintain the same compliance certifications?

A: The 84134310 maintains RoHS3 compliance, identical to the CWD4825-10. The 84137210N maintains RoHS compliance. Both parts are REACH affected or unaffected as specified in their individual datasheets.

Q: What is the primary difference between the two substitutes?

A: The 84134310 is a same-manufacturer substitute with identical load voltage range (48 V ~ 660 V). The 84137210N is a cross-manufacturer substitute with a reduced load voltage range (24 V ~ 280 V). Selection depends on application load voltage requirements.
