A2F1CCQ12VDC1.9R

Relay Automotive Overview

The A2F1CCQ12VDC1.9R is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features a Mini ISO form factor with bracket mounting capabilities. The device utilizes a 12VDC coil with a power rating of 1.9W and a resistance of 63 Ohms. It employs an SPDT (Single Pole Double Throw) contact arrangement, providing one normally open and one normally closed circuit. The unit is rated for a maximum switching current of 40A on the normally open contact and 30A on the normally closed contact at 14VDC. It supports a maximum switching voltage of 75VDC and a maximum switching power of 630W.

Relay Automotive Feature Summary

• SPDT contact configuration enabling simultaneous control of two separate circuits
• Mini ISO chassis design compatible with standard automotive fuse box brackets
• High current handling capacity suitable for demanding automotive loads
• Sealed construction to protect internal components from environmental factors

Relay Automotive Applications

• Automotive lighting circuits
• Accessory power distribution
• Fan and pump motor control
• General vehicle electrical load management

Relay Automotive Procurement Notes

Verify that the specific suffix '1.9R' corresponds to the 1.9W coil power rating and the required terminal configuration before ordering. Confirm compatibility with the target bracket mount type. Ensure the application voltage aligns with the 12VDC coil specification. Check for any regional compliance requirements such as RoHS or REACH status relevant to the manufacturing origin.

Relay Automotive Selection Notes

Select this model when an SPDT function is required within a compact Mini ISO footprint. The 12VDC coil voltage must match the vehicle's electrical system. Consider the 40A/30A current ratings to ensure adequate capacity for the intended load. Verify that the bracket mounting style fits the available space in the fuse panel or junction box compared to PCB pin alternatives.

Relay Automotive Part Context

This component belongs to the A2 series of automotive relays from CIT Relay and Switch. The series is characterized by robust switching capabilities and standardized dimensions for easy integration into existing automotive architectures. The Mini ISO variant specifically targets markets requiring compact, high-reliability switching solutions that fit within traditional fuse box layouts.

Relay Automotive Replacement Considerations

Direct substitutes may include other Mini ISO SPDT relays with identical 12VDC coil characteristics and matching 40A/30A contact ratings. Ensure the replacement part maintains the same bracket mounting interface and terminal layout to guarantee physical compatibility without modification.
