Substitute Part Grouping Explanation

The CB1A-M-12V qualifies as a direct substitute for the CB1AF-D-M-12V based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical coil voltage (12VDC) and coil current (117 mA)
• Identical contact form (SPST-NO) and contact rating (40 A)
• Identical switching voltage (14VDC - Nom), must operate voltage (7 VDC), and must release voltage (1.2 VDC)
• Identical operate time (15 ms)
• Identical mounting type (Chassis Mount) and termination style (Quick Connect - 0.250")
• Identical operating temperature range (-40°C ~ 85°C)
• Identical contact material (Silver Alloy, Cadmium Free)
• Identical coil power (1.4W) and coil resistance (103 Ohms)
