• Contact rating: 1 A
• Switching voltage: 115VAC, 28VDC - Max
• Coil current: 6.6 mA
• Coil type: Non Latching
• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Hermetically
• Operating temperature range: -65°C ~ 125°C
• Contact material: Silver Palladium (AgPd), Gold (Au)
• Coil resistance: 4 kOhms
• Must operate voltage: 14.2 VDC
• Must release voltage: 1.37 VDC
• Operate time: 4 ms
• Release time: 2.5 ms

The identified substitute parts J1MSW-26XM and 2-1617541-3 satisfy all critical electrical and mechanical parameters and are therefore direct equivalents suitable for interchangeable use.
