Substitute Part Grouping Explanation

Substitution of the DSP1-L2-DC3V is determined by strict equivalence across the following critical parameters:

  • Coil voltage specification (3VDC)
  • Contact configuration (DPST-NO/NC with dual coil latching)
  • Current rating (5A)
  • Switching voltage capability (250VAC, 125VDC maximum)
  • Mounting technology (through-hole with PC pin termination)
  • Thermal operating range (-40°C to 65°C)
  • Contact material composition (Silver Tin Oxide)
  • Coil resistance (30 Ohms)

The DSP1-L2-DC3V-F qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and packaging configuration.
