CWD48125 Equivalent & Substitute Parts

Part Overview

The CWD48125 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, rated for 125A load current across a 48V to 660V operating range. The part maintains active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD48125 is determined by electrical and mechanical parameter alignment. All identified substitute parts maintain identical specifications across the following critical parameters: SPST-NO circuit configuration, AC output with zero-cross switching, 4–32VDC input voltage range, 48–660V load voltage range, 125A load current rating, chassis mount configuration, screw terminal termination, and hockey puck package form factor. These parameters define the functional and physical interchangeability requirements for this SSR relay category. Substitute parts are listed based on direct manufacturer equivalency and manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CWD48125, 84134180, and 84137180N—satisfy the electrical and mechanical requirements for SPST-NO solid-state relay applications within the specified voltage and current parameters. Selection between these parts should be based on compliance requirements and product status:

The CWD48125 and 84134180 are both ROHS3 compliant and REACH affected, making them suitable for applications subject to these regulatory frameworks. The 84137180N is RoHS compliant and REACH unaffected, providing an alternative for applications where REACH compliance status is a determining factor. All three parts maintain active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the 84134180 be used as a direct replacement for the CWD48125?

A: Yes. Both parts share identical electrical specifications (SPST-NO circuit, AC zero-cross output, 4–32VDC input, 48–660V load voltage, 125A current rating) and mechanical form factor (hockey puck, chassis mount, screw terminal). Both are ROHS3 compliant and REACH affected.

Q: What is the difference between the CWD48125 and the 84137180N?

A: The primary differences are manufacturer (Sensata-Crydom versus Crouzet), series designation (CW48 versus GN), packaging format (bulk versus box), and regulatory status. The 84137180N is REACH unaffected, whereas the CWD48125 is REACH affected. All electrical and mechanical parameters are identical.

Q: Are there packaging considerations when substituting these parts?

A: The CWD48125 and 84134180 are supplied in bulk packaging, while the 84137180N is supplied in box packaging. This distinction affects receiving, storage, and inventory management procedures but does not impact electrical or mechanical compatibility.

Q: Which part should be selected for REACH-sensitive applications?

A: The 84137180N is REACH unaffected and is the appropriate selection for applications where REACH compliance status is a requirement. The CWD48125 and 84134180 are both REACH affected.

Q: Do all three parts support the same input and load voltage ranges?

A: Yes. All three parts operate across identical input voltage (4–32VDC) and load voltage (48–660V) ranges with a 125A load current rating.
