Relay Automotive Procurement Notes

Verify the specific terminal type and coil voltage against the target application requirements before ordering. Confirm that the chassis mounting bracket aligns with the available space in the assembly. Ensure the operating temperature range meets the environmental conditions of the intended installation site to guarantee reliable performance over the product lifecycle.

Relay Automotive Selection Notes

Select this component when an 80A switching capacity is required for 12VDC automotive or industrial applications. The SPST-NO configuration suits simple on/off control scenarios. Consider the sealed design and integrated diode for environments where reliability and circuit protection are critical. Compare physical dimensions and terminal styles against existing board or panel layouts to ensure mechanical compatibility.

Relay Automotive Part Context

This part belongs to the A3M series of automotive relays from CIT Relay and Switch. The series is characterized by large switching capacities and durable construction suitable for harsh environments. Variants within the series typically differ by coil voltage and terminal configuration, offering flexibility for various vehicle and equipment architectures while maintaining consistent performance standards.

Relay Automotive Replacement Considerations

Direct substitutes include the A3M1ASQ12VDC2D and A3M1ASP12VDC2D variants from the same manufacturer family. Verify that alternative parts match the 80A rating, 12VDC coil specification, and SPST-NO contact form. Ensure mechanical mounting interfaces and terminal types are compatible with the existing system design.
