Substitute Part Grouping Explanation

Substitution eligibility for the CMD2490-10 is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) topology
• Output Type: Must be AC switching
• Input Voltage Range: Must accommodate 3 ~ 32VDC control signal
• Load Voltage Range: Must support 24 V ~ 280 V operation
• Load Current Rating: Must equal or exceed 90A
• Mounting Configuration: Must be Chassis Mount with Hockey Puck package
• Termination: Must use Screw Terminal connections
• Compliance: Must maintain RoHS compliance status

The substitute part 84137240 meets all substitution criteria with an increased load current rating of 100A, providing enhanced current capacity while maintaining identical input/output voltage specifications and mechanical compatibility.
