Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required coil voltage and contact configuration. Confirm RoHS compliance status and manufacturing certifications such as QS-9000 or ISO-9002 if required for your supply chain standards. Check datasheet revisions for any updates to specifications or availability before finalizing procurement orders.

Relay Automotive Selection Notes

Select this model when a 6VDC coil drive is available and a single-pole normally-open contact is needed. Ensure the load current does not exceed 40A at 14VDC. Consider the operating temperature range of -40°C to 125°C for environmental compatibility. Verify terminal type requirements against the quick-connect specification.

Relay Automotive Part Context

This component belongs to the A2 series of automotive relays from CIT Relay and Switch. The series is characterized by large switching capacities and compact dimensions. It is certified under QS-9000 and ISO-9002 standards, indicating suitability for automotive industry quality requirements. The product line includes various coil voltages and contact arrangements.

Relay Automotive Replacement Considerations

Direct substitutes within the same family include A2S1ASQ12VDC1.6 and A2S1ASQ24VDC1.6, which share identical mechanical and contact specifications but differ in coil voltage. Ensure the replacement coil voltage matches the system design to prevent malfunction.
