Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CWD2450P are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Circuit configuration: SPST-NO (1 Form A) topology
• Output switching type: AC with zero-cross capability
• Load current rating: 50 A minimum
• Package form factor: Hockey puck chassis mount
• Termination interface: Screw terminal connection
• Input control voltage compatibility: Overlapping or encompassing DC voltage range
• Load voltage capability: Must support the required application voltage range

The substitute part 84138120N (Crouzet GN+ series) meets these criteria with compatible electrical specifications and identical mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD2450P and 84138120N are active production components with current availability. The CWD2450P maintains ROHS3 compliance status, while the 84138120N carries RoHS compliance. The 84138120N provides extended load voltage capability (24 V ~ 500 V versus 24 V ~ 280 V), which represents a superset of the CWD2450P operating range. Input voltage compatibility is maintained across both units within the specified control circuit requirements. Selection between these parts should be based on supply chain availability, lead time requirements, and compliance certification alignment with end-application standards.

Frequently Asked Questions (FAQ)

Q: Can the 84138120N replace the CWD2450P in existing applications?

A: Yes, provided the application load voltage does not exceed 280 V. The 84138120N supports this voltage range and maintains identical circuit topology, current rating, and mechanical packaging. Input voltage range compatibility is confirmed (4 ~ 32 VDC encompasses typical control circuit requirements).

Q: What are the key compatibility factors for SSR substitution?

A: Circuit type (SPST-NO), output switching method (AC zero-cross), load current capacity (50 A), package form factor (hockey puck), and termination style (screw terminal) must remain constant. Input voltage range and load voltage range must be compatible with the application requirements.

Q: Are there packaging differences between these parts?

A: Both parts use hockey puck chassis mount packaging with screw terminal connections. The CWD2450P is supplied in bulk packaging, while the 84138120N is supplied in box packaging. Mechanical mounting and electrical interface compatibility is maintained.

Q: What compliance differences exist between these parts?

A: The CWD2450P is ROHS3 compliant and REACH affected. The 84138120N is RoHS compliant and REACH unaffected. Application compliance requirements should determine part selection when regulatory certification is a factor.
