Relay Automotive Procurement Notes

Verify the specific terminal style required for your assembly, as this model supports quick connect mounting. Confirm that the 24VDC coil voltage aligns with your system's power supply capabilities. Ensure the 40A current rating meets the peak load requirements of the intended circuit. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the operating temperature range against your application's thermal environment.

Relay Automotive Selection Notes

Select this relay when a high-current DC switch is needed within an automotive context. The SPST-NO configuration is ideal for simple on/off control of loads like lamps or motors. Consider the 75VDC maximum switching voltage limit when designing the circuit. The quick connect interface simplifies wiring compared to soldered connections. Evaluate the 1.6W coil power consumption against available driver current sources.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch. The series is characterized by ISO-sized form factors and robust construction for vehicle use. Variants in this family differ primarily by coil voltage, contact arrangement, and terminal type. The A2M1ASP24VDC1.6D specifically denotes the 24V coil, SPST-NO contact, and quick connect terminal configuration.

Relay Automotive Replacement Considerations

Compatible substitutes include other ISO-sized automotive relays with matching 24VDC coil voltage and 40A current rating. Verify that replacement parts support quick connect terminals or adapt accordingly. Ensure the new component meets the same 75VDC switching voltage requirement. Cross-reference pinouts and mechanical dimensions to guarantee fitment.
