• Compact physical dimensions facilitate installation in space-constrained automotive applications
• Quick connect terminal style enables rapid assembly and maintenance

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory control systems
• General automotive electrical load switching

Relay Automotive Procurement Notes

Verify the specific contact form matches the circuit requirement, as SPDT configurations differ functionally from SPST alternatives. Confirm that the 20VDC maximum switching voltage rating aligns with the target application's electrical parameters. Ensure the quick connect terminal type is compatible with existing harness connectors to prevent interface mismatches during integration.

Relay Automotive Selection Notes

Select this component when a sealed, compact relay is required for low-voltage automotive loads. The SPDT configuration provides flexibility for common or separate load paths. Consider the 25A current rating against peak operational demands. The 12VDC coil specification suits standard vehicle battery systems. Evaluate the physical footprint against available mounting space constraints within the vehicle architecture.

Relay Automotive Part Context

This part belongs to the CIT Relay and Switch automotive relay portfolio, which emphasizes durability and compactness for vehicular use. The series typically includes various contact forms and coil voltages to support diverse automotive electronic needs. The A161CS variant specifically addresses applications requiring sealed protection and small form factors.

Relay Automotive Replacement Considerations

Direct substitutes must match the SPDT contact form, 12VDC coil voltage, and similar physical dimensions. Verify that alternative parts meet or exceed the 25A current and 20VDC voltage ratings. Ensure compatibility with quick connect interfaces to maintain assembly integrity.
