Critical Matching Parameters:

• Coil voltage: 12 VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 250 mA
• Switching voltage: 100 VAC, 100 VDC maximum
• Coil current: 24 mA
• Coil type: Non Latching
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -20°C to 85°C
• Coil resistance: 500 Ohms
• Must operate voltage: 9.6 VDC
• Must release voltage: 1 VDC
• Operate time: 1 ms
• Release time: 1 ms

The 8L41-12-101 maintains full electrical and mechanical compatibility with the obsolete 8041-12-101 across all specified parameters. The primary distinction is product status: the 8041-12-101 is obsolete while the 8L41-12-101 is active, making the latter the appropriate selection for new designs and ongoing procurement.
