CWD4825 Equivalent & Substitute Parts

Part Overview

The CWD4825 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 functions as an AC output relay with zero-cross switching capability, designed for industrial switching applications requiring 25A load capacity at voltages between 48V and 660V. The device is actively produced and RoHS compliant, making it suitable for modern industrial control systems. Equivalent parts may be required due to supply chain considerations, regional availability, or specific packaging preferences while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD4825 is determined by strict equivalence across the following critical parameters: circuit configuration (SPST-NO), output type (AC with zero-cross switching), input voltage range (4 ~ 32VDC), load voltage range (48 V ~ 660 V), load current capacity (25 A), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). All identified substitute parts maintain these specifications without deviation. Packaging format (bulk versus box) and manufacturer differences do not affect electrical or mechanical compatibility. Product status (active) and RoHS compliance are maintained across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CWD4825, 84134110, and 84137110N—are functionally equivalent and directly interchangeable based on electrical specifications and mechanical form factor. Selection between these alternatives should be based on availability, lead time, and packaging requirements. The CWD4825 and 84137110N share identical ECCN and HTSUS classifications (EAR99 and 8536.49.0080 respectively), while 84134110 carries a different HTSUS code (8536.41.0060). All parts maintain active product status and full RoHS compliance. Moisture sensitivity levels vary (CWD4825: not applicable; 84134110 and 84137110N: MSL 1 unlimited), which does not impact performance in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can CWD4825 be directly replaced with 84134110 or 84137110N? A: Yes. All three parts are electrically and mechanically equivalent. They share identical circuit configuration, voltage ratings, current capacity, and package form factor. Direct substitution is permissible without circuit modification.

Q: Are there differences in packaging that affect compatibility? A: CWD4825 and 84134110 are supplied in bulk packaging, while 84137110N is supplied in box packaging. This distinction affects only procurement and storage; electrical and mechanical compatibility remains unchanged.

Q: Do the different manufacturers affect performance? A: No. All three manufacturers (Sensata-Crydom, Sensata Technologies, and Crouzet) produce parts meeting identical electrical and mechanical specifications for this application. Manufacturer selection is based on supply chain and availability factors.

Q: What are the critical parameters for substitution? A: The following parameters must remain constant for substitution: SPST-NO circuit configuration, AC output with zero-cross switching, 4 ~ 32VDC input voltage, 48 V ~ 660 V load voltage range, 25A load current, chassis mount configuration, screw terminal termination, and hockey puck package form factor.

Q: Are all parts RoHS compliant? A: Yes. CWD4825, 84134110, and 84137110N are all RoHS compliant and suitable for applications requiring environmental compliance.
