A3M1CCQ12VDC2D

Relay Automotive Overview

The A3M1CCQ12VDC2D is an automotive SPDT relay manufactured by CIT Relay and Switch. It features a 12VDC coil with a resistance of 90 ohms (+/- 10%). The contact arrangement supports switching capacities up to 80A at 14VDC for the normally open circuit and 70A for the normally closed circuit. Maximum switching voltage is 75VDC, with a maximum power rating of 1120W. Contact material is AgSnO2 mixed with In2O3, ensuring initial contact resistance below 30 milliohms. The unit measures 28.5 x 28.5 x 26.5 mm.

Relay Automotive Feature Summary

• High current switching capacity suitable for heavy-duty automotive loads
• Dual-circuit SPDT configuration allowing independent control of normally open and normally closed paths
• Robust contact material composition for reliable performance in harsh environments

Relay Automotive Applications

• Automotive lighting systems
• Lamp accessories
• Heavy-duty electrical load switching

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact coil resistance and contact rating variations. Ensure compatibility with QS-9000 and ISO-9002 certified manufacturing standards required for your assembly line. Cross-reference the pinout configuration with your PCB design to prevent installation errors during integration.

Relay Automotive Selection Notes

Select this component when high current handling above standard relay limits is required for automotive applications. The SPDT architecture provides flexibility for complex circuit control compared to simple SPST units. Consider the physical dimensions and mounting options to ensure fit within the designated enclosure space alongside other electronic components.

Relay Automotive Part Context

This part belongs to the CIT A3 series of automotive relays, designed specifically for high-current switching tasks. The series is characterized by large switching capacities and compact form factors suitable for modern vehicle electrical architectures. It represents a specialized solution for managing significant electrical loads in transportation equipment.

Relay Automotive Replacement Considerations

Direct substitutes include A3M1BCP12VDC1DR and A3M1USQ12VDC1R from the same manufacturer family. Verify that alternative parts match the 12VDC coil specification and SPDT contact arrangement before substitution.
