Substitute Part Grouping Explanation

Substitution of the G7L-2A-BUB DC48 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part G7L-2A-B DC48 maintains identical specifications across the following key parameters:

• Coil voltage: 48VDC
• Contact form: DPST-NO (2 Form A)
• Contact rating: 25 A at 250VAC maximum
• Coil current: 40 mA
• Mounting configuration: Chassis mount with screw terminals
• Operating temperature range: -25°C to 60°C
• Contact material composition: Silver Tin Indium (AgSnIn)
• Electrical performance: Must operate at 36VDC, must release at 7.2VDC
• Switching characteristics: 30 ms operate time, 30 ms release time
• Regulatory compliance: RoHS compliant

Both parts share the same base product number (G7L-2A) and series designation, confirming their functional equivalence. The difference in part number suffix reflects packaging configuration only, with no impact on electrical or mechanical performance.
