Relay Automotive Procurement Notes

Verify that the specific part number matches the required SPST-NO configuration and 30A rating. Confirm through-hole package compatibility with your PCB layout. Ensure the 12V DC coil voltage aligns with your system's supply. Cross-reference manufacturer datasheets to validate operating temperature ranges and mechanical durability specifications before finalizing procurement decisions.

Relay Automotive Selection Notes

Select this model when a robust SPST-NO relay with high current handling is required for 12V automotive systems. Consider the 5ms operate time for timing-sensitive applications. Evaluate the through-hole mounting style against available board space and assembly methods. Compare against similar CIT models like the A61AS series if different contact forms are needed.

Relay Automotive Part Context

This component belongs to the CIT Relay and Switch automotive relay family, which specializes in durable electromechanical switches for vehicle electronics. The A61 series is characterized by its ability to handle significant currents while maintaining compact dimensions. These relays are widely used in modern vehicles for managing high-power accessories and critical engine functions.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT Automotive Relays with identical SPST-NO configurations and 12V DC coils. Verify pinout compatibility and physical dimensions before swapping. Models such as the A61AS12VDC1.3D offer similar performance but require confirmation of contact form differences.
