Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of the internal coil resistor and the exact contact rating configuration. Ensure the selected variant matches the required coil voltage and switching current parameters for the target application. Cross-reference the datasheet to confirm RoHS compliance status and mounting style availability before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a sealed SPDT relay with a 12VDC coil and integrated resistor is required. Consider the 50A switching capacity for heavy-duty loads. Verify that the quick connect termination style aligns with the existing harness or PCB layout. Confirm that the operating temperature range meets the environmental conditions of the intended installation site.

Relay Automotive Part Context

This part belongs to the CIT A2 series of automotive relays, characterized by compact dimensions and robust switching capabilities. The series includes variants with different contact arrangements and coil voltages. The A2H1CCQ12VDC1.6R specifically denotes a sealed unit with a 12V coil and resistor, distinguishing it from unsealed or non-resistor versions within the same product family.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A2 series relays with matching 12VDC coil voltage and similar current ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure the replacement part maintains the sealed construction and quick connect termination style if environmental sealing and mounting constraints are critical.
