Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's latest documentation to confirm if it denotes a resistor-equipped variant or a specific packaging designation. Ensure the 6VDC coil voltage matches the target system requirements. Confirm that the quick-connect pin dimensions align with existing socket infrastructure before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a single-pole normally-open configuration is required for low-voltage automotive loads. The 6VDC coil specification necessitates compatibility with six-volt electrical architectures. Consider the 40A current rating to ensure adequate capacity for the intended load without exceeding thermal limits during continuous operation cycles.

Relay Automotive Part Context

This model belongs to the CIT A2 series of mini ISO-sized automotive relays. These components are engineered for durability in vehicle under-hood and interior applications. The series typically features sealed housings and robust contact materials to withstand vibration and environmental exposure common in modern transportation platforms.

Relay Automotive Replacement Considerations

Direct substitutes within the same family include A2S1ASQ6VDC1.6. Verify functional equivalence regarding coil voltage, contact form, and terminal pitch before swapping. Cross-reference mechanical dimensions to ensure fitment within the designated relay socket space.
