Relay Automotive Procurement Notes

Verify the specific suffix 'D' against manufacturer documentation to confirm terminal configuration and shroud details. Ensure the 48VDC coil voltage aligns with the target circuit design. Confirm RoHS compliance status through official datasheets prior to integration. Cross-reference the 40A contact rating with actual load requirements to prevent operational failure.

Relay Automotive Selection Notes

Select this component when a single-pole double-throw configuration is required in a compact automotive form factor. The 48VDC coil specification makes it suitable for heavy-duty vehicle platforms. Consider the sealed design for protection against environmental contaminants. Evaluate the quick-connect interface against available harness connectors to ensure mechanical compatibility during assembly.

Relay Automotive Part Context

This relay belongs to the CIT A2 series, which is characterized by small size and light weight relative to its switching capacity. The series is certified under QS-9000 and ISO-9002 manufacturing standards, indicating adherence to rigorous quality controls for automotive supply chains. The A2 series provides reliable performance for high-current switching tasks in demanding conditions.

Relay Automotive Replacement Considerations

Compatible substitutes within the same family include A2S1CSQ48VDC1.6R. Verify that alternative part numbers maintain identical coil voltage, contact arrangement, and termination style before substitution.
