Substitute Part Grouping Explanation

Substitute parts for the LY2-D DC48 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Coil voltage: 48VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 10 A
• Switching voltage: 250VAC, 125VDC - Max
• Coil current: 18.5 mA
• Coil type: Non Latching
• Mounting type: Socketable
• Termination style: Plug In
• Operating temperature range: -25°C ~ 55°C
• Contact material: Silver Alloy
• Coil resistance: 2.6 kOhms
• Must operate voltage: 38.4 VDC
• Must release voltage: 4.8 VDC
• Operate time: 25 ms
• Release time: 25 ms

The LY2-DC48 meets all these criteria and is classified as a parametric equivalent substitute.
