Relay Automotive Procurement Notes

Verify the specific contact material composition, as sources indicate AgSnO or AgSnO/InO variants within this series. Confirm the exact terminal style matches the quick connect requirement. Ensure the 24VDC coil rating aligns with the target circuit voltage. Check RoHS compliance status for regulatory adherence. Validate the operating temperature range against environmental conditions.

Relay Automotive Selection Notes

Select this model for applications requiring a single normally open contact with high current handling capabilities. The 24VDC coil specification suits standard automotive electrical architectures. Consider the sealed design for protection against moisture and contaminants. Evaluate the physical dimensions and mounting style against available board space. Compare against other A-series relays if different contact arrangements are needed.

Relay Automotive Part Context

This component belongs to the CIT A Series, a line of general-purpose automotive relays known for large switching capacities and small form factors. The series includes various coil voltages and contact configurations, certified under QS-9000 and ISO-9002 standards. These relays are designed for durability in demanding automotive environments.

Relay Automotive Replacement Considerations

The A51AS24VDC1.6 is a direct functional substitute with identical specifications but potentially different contact material variations. Verify terminal compatibility when swapping between these part numbers.
