Relay Automotive Procurement Notes

Verify the specific suffix 'D' indicates the inclusion of an internal diode if required by your circuit design, as datasheets may vary regarding built-in suppression components. Confirm that the 12VDC coil voltage aligns with your system's nominal supply. Ensure the through-hole mounting style fits your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Relay Automotive Selection Notes

Select this model when a sealed relay with high current handling is necessary for automotive or industrial use. The SPDT configuration offers flexibility for normally open and normally closed functions. Consider the 1.6W coil power for thermal management in dense assemblies. Verify that the 75VDC rating exceeds your maximum switching voltage requirements to ensure safe operation under all conditions.

Relay Automotive Part Context

This component belongs to the CIT A3K series of automotive relays, characterized by large switching capacities and compact dimensions relative to their current ratings. The series is certified under QS-9000 and ISO-9002 standards, indicating adherence to strict quality management systems for automotive suppliers. These relays are engineered for durability in vibration-prone environments typical of vehicle applications.

Relay Automotive Replacement Considerations

Compatible substitutes include the A3M1BCP12VDC1DR and A3K1CSQ12VDC1.6D, which share similar 12VDC coil specifications and high-current capabilities within the CIT product line. Ensure mechanical footprint compatibility before substitution.
