Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm the inclusion of any integrated components such as resistors or diodes. Ensure the 24VDC coil rating matches the system supply voltage. Confirm that the 80A contact rating aligns with the load requirements and that the Maxi ISO footprint fits the designated enclosure space.

Relay Automotive Selection Notes

Select this component when a high-current, high-voltage DC switching solution is required within a standard automotive relay footprint. The SPDT configuration allows for both normally open and normally closed connections. Consider the internal blowout magnets for applications involving significant inductive loads or frequent switching cycles where arc erosion is a concern.

Relay Automotive Part Context

This part belongs to the CIT Maxi ISO series, designed to replace common OEM automotive relays. The series offers various coil voltages and contact configurations. The A3KM1 variant specifically denotes the SPDT configuration with a 24VDC coil, providing a direct replacement option for legacy systems utilizing similar form factors.

Relay Automotive Replacement Considerations

The datasheet references A3KM1CSQ24VDC1.6D as a related variant. Verify if the 'D' suffix indicates a different mounting style or terminal configuration compared to the 'R' version. Ensure compatibility with existing PCB traces or socket terminals before substitution.
