Key Parameters

Substitute Part Grouping Explanation

The substitute part 84137180N (Crouzet, Series GN) qualifies as an equivalent based on the following matching parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Load current rating: 125 A
• Package type: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Input voltage range: 4 ~ 32VDC (overlaps with 3 ~ 32VDC)
• RoHS compliance: Both parts are RoHS compliant

The substitute part operates within a higher load voltage range (48 V ~ 660 V) compared to the main part (24 V ~ 280 V), making it suitable for applications requiring the CWD24125P's voltage specifications while providing extended capability for higher voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWD24125P and 84137180N are active production components with RoHS compliance certification. Selection between these parts should be based on load voltage requirements: the CWD24125P is specified for 24 V to 280 V applications, while the 84137180N accommodates 48 V to 660 V loads. For applications operating within the 24 V to 280 V range, either part is electrically suitable. The 84137180N provides extended voltage capability for systems requiring higher load voltage operation. Packaging and termination characteristics are identical, ensuring mechanical compatibility in chassis-mount installations with screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can the 84137180N replace the CWD24125P in all applications?

A: The 84137180N is electrically compatible for applications within the CWD24125P's specified load voltage range (24 V ~ 280 V). Both parts share identical circuit topology, current rating, package type, and termination style. The 84137180N's extended voltage range (48 V ~ 660 V) does not restrict its use in lower voltage applications.

Q: What are the key compatibility criteria for these SSR relays?

A: Compatibility is determined by matching circuit type (SPST-NO), output type (AC with zero-cross), load current capacity (125 A), input voltage range overlap, package configuration (hockey puck), mounting method (chassis mount), and termination style (screw terminal).

Q: Are there input voltage differences between these parts?

A: The CWD24125P operates with 3 ~ 32VDC input, while the 84137180N operates with 4 ~ 32VDC input. The 84137180N's minimum input voltage is 1V higher, but both parts function across the standard 24VDC control signal range used in industrial applications.

Q: Do both parts have the same physical footprint?

A: Yes. Both the CWD24125P and 84137180N use the hockey puck package with chassis mount configuration and screw terminal termination, ensuring identical mechanical compatibility in existing installations.

Q: What is the significance of the zero-cross output type?

A: Zero-cross switching synchronizes relay activation with the AC voltage waveform's zero-crossing point, reducing electromagnetic interference and switching stress on connected loads. Both parts incorporate this feature.
