Relay Automotive Procurement Notes

Verify the specific ordering suffix 'R' indicates the inclusion of a 680 ohm resistor in the coil circuit, as distinct from non-resistor variants. Confirm the package type matches the quick connect termination requirement. Ensure the 12VDC coil voltage aligns with the target system's nominal voltage. Check RoHS compliance status if required by project specifications. Validate that the 40A rating meets the load current requirements for the intended application.

Relay Automotive Selection Notes

Select this component when a sealed SPDT relay with high current capacity is required for automotive use. The 12VDC coil voltage is standard for vehicle systems. The integrated resistor reduces coil current surge. Consider the physical dimensions and mounting style for PCB or panel installation. Ensure the 75VDC max switching voltage exceeds the circuit operating voltage.

Relay Automotive Part Context

This part belongs to the CIT A2 series of automotive relays, characterized by compact size and high switching capacity. The A2M1CCQ12VDC1.6R specifically denotes the SPDT configuration with quick connect pins and a 12VDC coil. It is designed for reliability in harsh automotive environments, meeting QS-9000 and ISO-9002 manufacturing standards.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A2 series relays with matching SPDT configuration and 12VDC coil voltage. Verify that any replacement maintains the 40A contact rating and sealed housing. Ensure the pinout and terminal type (quick connect) are compatible with the existing board layout.
