Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSP1-L2-DC9V is determined by strict equivalence across the following critical parameters:

• Coil voltage: 9VDC
• Contact configuration: DPST-NO/NC (1 Form A, 1 Form B)
• Current rating: 5A
• Switching voltage capability: 250VAC, 125VDC maximum
• Coil type: Latching, dual coil
• Mounting method: Through hole with PC pin termination
• Operating temperature range: -40°C to 65°C
• Contact material composition: Silver Tin Oxide (AgSnO)

The DSP1-L2-DC9V-F qualifies as a direct substitute based on identical electrical specifications, mechanical configuration, and contact characteristics. The primary distinction is product status and packaging format.
