Relay Automotive Procurement Notes

Verify that the specific suffix 'R' corresponds to the required mounting bracket or shroud configuration as indicated in distributor listings. Confirm the 48VDC coil rating matches the target circuit requirements. Ensure the quick connect termination style aligns with the PCB or harness interface. Check RoHS compliance status if restricted substances are a concern for the application.

Relay Automotive Selection Notes

Select this model when a 48VDC coil voltage is required for automotive applications. The 40A rating supports high-power loads such as lighting or starter circuits. The sealed design is suitable for harsh environments. Compare against other A2 series variants if different coil voltages or contact configurations like SPDT are needed. Ensure the physical dimensions fit the available chassis space.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, which are characterized by their small size and large switching capacity. The series includes various coil voltages and contact arrangements. The A2M1ASQ variant specifically denotes the 48VDC coil version with SPST-NO contacts and quick connect terminals, often including a metal bracket for secure installation.

Relay Automotive Replacement Considerations

Compatible substitutes within the same family include A2S1ASQ48VDC1.6R and A2F1BSQQ48VDC1.6, provided the contact configuration and mounting style match. Verify that any replacement part maintains the 40A current rating and 48VDC coil specification. Ensure the sealing type and terminal style are identical to avoid wiring modifications.
