Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSP1-L2-5V is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (5VDC)
• Contact configuration (DPST-NO/NC with 1 Form A, 1 Form B)
• Current rating (5 A minimum)
• Switching voltage capability (250VAC, 125VDC maximum)
• Coil type (Latching, Dual Coil)
• Mounting method (Through Hole with PC Pin termination)
• Seal rating (Sealed - Fully)
• Operating temperature range (-40°C ~ 65°C)
• Contact material (Silver Tin Oxide)

The DSP1-L2-DC5V-F meets all these criteria and is classified as an equivalent substitute part.
