A2K1CSQ12VDC1.6D

Relay Automotive Overview

The A2K1CSQ12VDC1.6D is a sealed SPDT automotive relay manufactured by CIT Relay and Switch, designed for high-current DC applications. It features a 12VDC coil with a rated power of 1.6W and a maximum switching voltage of 110VDC. The contact arrangement supports up to 120A switching current, making it suitable for heavy loads such as DC motors and lamps. The unit measures 26x26x24.5mm and utilizes quick connect terminals for secure installation.

Relay Automotive Feature Summary

• Sealed construction with internal blowout magnets for reliable operation
• High switching capacity capable of handling up to 120A
• Compact ISO-sized form factor with quick connect termination

Relay Automotive Applications

• DC motor control circuits
• Automotive lamp accessories
• Heavy load switching in vehicle systems

Relay Automotive Procurement Notes

Verify the specific suffix 'D' indicates the inclusion of an integrated diode or suppression component, as this affects circuit compatibility. Confirm that the 120A rating aligns with your peak load requirements rather than continuous duty limits. Ensure the socket type matches the quick connect pin spacing. Cross-reference the datasheet for thermal derating curves if operating in enclosed environments.

Relay Automotive Selection Notes

Select this model when a standard ISO relay requires higher current handling than typical 30A or 40A variants. The SPDT configuration allows for complex switching logic compared to single-pole options. Consider the 110VDC max rating if interfacing with higher voltage DC sources. The sealed design is preferred for harsh automotive environments where moisture resistance is critical.

Relay Automotive Part Context

This component belongs to the A2K series of mini ISO automotive relays from CIT Relay and Switch. It shares the physical footprint with other ISO-standard relays but distinguishes itself through enhanced current capacity and specific coil characteristics. The series is widely used in modern vehicle electrical architectures requiring robust switching solutions.

Relay Automotive Replacement Considerations

Direct substitutes include the A2KICSQ12VDCC1.6D for similar Mini ISO specifications. Verify that any replacement maintains the SPDT contact arrangement and compatible coil voltage. Ensure the alternative part supports the required 120A switching current and includes necessary surge suppression if the original 'D' suffix implies a built-in diode.
