A2M1CCQ12VDC1.9

Relay Automotive Overview

The A2M1CCQ12VDC1.9 is a CIT Relay and Switch automotive relay featuring a SPDT contact arrangement with a 20A normally open and 15A normally closed rating at 14VDC. It operates on a 12VDC coil with a rated power of 1.9W and a resistance of 63 ohms. The device supports quick connect mounting, offers large switching capacity up to 40A, and maintains a compact size for efficient integration in vehicle electrical systems.

Relay Automotive Feature Summary

• SPDT configuration providing independent normally open and normally closed circuits
• Quick connect terminal design for simplified installation
• Compact form factor suitable for space-constrained automotive applications

Relay Automotive Applications

• Automotive lighting control systems
• Vehicle accessory power distribution
• General purpose automotive circuit switching

Relay Automotive Procurement Notes

Verify the specific contact arrangement suffix matches the required SPDT configuration. Confirm coil voltage tolerance aligns with the 12VDC system requirements. Ensure the quick connect terminal style is compatible with existing harness connectors. Check RoHS compliance status if environmental regulations apply to the assembly.

Relay Automotive Selection Notes

Select this model when a single pole double throw function is required within a compact automotive relay footprint. The 1.9W coil power consumption is suitable for standard vehicle electrical loads. Verify that the 20A NO and 15A NC ratings exceed the maximum current demands of the controlled circuits to ensure reliable operation under load conditions.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, designed for rugged performance in harsh environments. The series utilizes silver tin oxide contacts to handle high switching currents while maintaining low contact resistance. The A2M1 variant specifically denotes a mini ISO form factor optimized for modern vehicle wiring architectures.

Relay Automotive Replacement Considerations

Direct substitutes include the A2M1CCQ12VDC1.6D which shares the same SPDT contact arrangement and physical dimensions but features a different coil power rating. Ensure the replacement part number matches the specific coil resistance and operating voltage thresholds required by the circuit design.
