Key Parameters

Substitute Part Grouping Explanation

The DK1A-L2-3V-F qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Coil voltage: 3VDC (identical)
• Contact form: SPST-NO (1 Form A) (identical)
• Contact rating: 10 A (identical)
• Switching voltage: 250VAC, 125VDC - Max (identical)
• Load capacity: 2500VA, 1250W (identical)
• Coil type: Latching, Dual Coil (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pin (identical)
• Operating temperature range: -40°C ~ 65°C (identical)
• Contact material: Silver Tin Oxide (AgSnO) (identical)
• Coil resistance: 45 Ohms (identical)
• Coil current: 66.7 mA (identical)
• Timing characteristics: 10 ms operate, 8 ms release (identical)

The primary distinction is product status: DK1A-L2-3V is obsolete, while DK1A-L2-3V-F is active, and packaging differs (standard packaging versus box packaging).

Parameter Comparison
