Key Parameters

Substitute Part Grouping Explanation

The D2440T has one identified substitute part: the Crouzet 84137450N. Substitution eligibility is determined by the following criteria derived from the provided specifications:

• Product category classification as a solid state relay
• Active product status ensuring ongoing manufacturer support and availability
• RoHS compliance status matching regulatory requirements
• Moisture Sensitivity Level 1 classification indicating equivalent environmental handling
• ECCN and HTSUS classifications for export and tariff consistency

The Crouzet 84137450N meets these core substitution parameters and is therefore classified as a manufacturer-recommended equivalent for the D2440T.
