Relay Automotive Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required terminal types and mounting configurations. Confirm that the 24VDC coil specification matches the target system voltage. Check for RoHS compliance requirements if applicable to the end product. Ensure the chassis mount style aligns with the available panel or enclosure space in the design.

Relay Automotive Selection Notes

Select this model when a high-current single-pole switch is required for 24VDC automotive applications. The sealed design protects against environmental contaminants. Consider the 80A rating for heavy loads such as lamps or motors. Verify that the chassis mounting method fits the assembly constraints. Compare response times if rapid switching is critical for the specific application logic.

Relay Automotive Part Context

This component belongs to the A3 series of automotive relays from CIT Relay and Switch. The series is characterized by large switching capacities and robust construction suitable for harsh environments. The A3F1 variant specifically denotes a sealed chassis mount relay. This family is certified under QS-9000 and ISO-9002 standards, indicating adherence to strict manufacturing quality controls for the automotive sector.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include models with different coil voltages or contact arrangements. For example, the A3M1ASQ24VDC2D shares similar specifications but may differ in package details. Always verify pinout compatibility and mechanical dimensions before substituting.
