Relay Automotive Overview

The A2HM1CCQ12VDC1.6D is an automotive SPDT relay manufactured by CIT Relay and Switch, designed for high-current applications with a switching capacity up to 50A at 14VDC. It operates on a 12VDC coil voltage with a resistance of 90 ohms and consumes 1.6W of power. The unit features quick connect mounting terminals and a sealed construction suitable for harsh environments. Key electrical parameters include a maximum switching voltage of 145VDC and a contact arrangement of one Form C.

Relay Automotive Feature Summary

• High current switching capability up to 50A
• Sealed construction for environmental protection
• Quick connect terminal mounting style

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory control systems
• Industrial motor control applications

Relay Automotive Procurement Notes

Verify the specific coil resistance and power rating against the official datasheet to ensure compatibility with the driving circuit. Confirm that the quick connect terminal type matches the harness connectors in the assembly. Check for any required diode specifications if the load is inductive, as this affects circuit protection design.

Relay Automotive Selection Notes

Select this component when a high-current SPDT relay is required for automotive or industrial use. Ensure the 12VDC coil voltage aligns with the system supply. Consider the 50A switching capacity for heavy loads. Verify that the physical dimensions and quick connect pin layout fit the available board space and connector constraints.

Relay Automotive Part Context

This part belongs to the CIT automotive relay series, characterized by robust sealing and high current handling. It is distinct from lower-current signal relays and general-purpose PCB mounted units. The model designation indicates the specific coil voltage, contact configuration, and terminal style within the manufacturer's catalog.

Relay Automotive Replacement Considerations

Direct substitutes may include other 12VDC SPDT automotive relays with similar 50A ratings and quick connect terminals. Verify mechanical footprint and pinout compatibility before substitution. Cross-reference with CIT part numbers like A21CSQ12VDC1.6D for similar form factors but different current ratings.
