A2F1CSP12VDC1.6D

Relay Automotive Overview

The A2F1CSP12VDC1.6D is a non-latching automotive relay from the CIT A2 series, designed for chassis mounting with quick connect termination. It features an SPDT (1 Form C) contact arrangement and operates on a 12VDC coil voltage. The unit supports a maximum switching current of 40A at 14VDC and handles up to 75VDC. Key electrical parameters include a coil resistance of 90 Ohms (+/- 10%) and a rated coil power of 1.6W. The device utilizes AgSnO2 contact material with initial contact resistance under 30 milliohms.

Relay Automotive Feature Summary

• Features internal blowout magnets to enhance arc suppression during switching operations
• Offers ISO-sized form factor suitable for standard automotive relay sockets
• Provides high switching capacity capable of controlling DC motors and lamp loads

Relay Automotive Applications

• Automotive DC motor control circuits
• Automotive lamp accessory management
• General automotive chassis-mounted switching applications

Relay Automotive Procurement Notes

Verify that the specific part number matches the required SPDT configuration and 12VDC coil specification. Confirm that the quick connect termination style aligns with the target PCB or wiring harness interface. Ensure the chassis mount design fits the available enclosure space. Check for RoHS compliance requirements if applicable to the final assembly standards.

Relay Automotive Selection Notes

Select this component when a compact, high-current automotive relay is needed for chassis installation. The SPDT configuration allows for single-pole double-throw switching functionality. Consider the 1.6W coil power consumption for battery load calculations. Verify that the 40A current rating meets the peak load requirements of the controlled circuit.

Relay Automotive Part Context

This model belongs to the CIT A2 series of automotive relays, which are characterized by their robust construction and suitability for harsh automotive environments. The series includes various contact arrangements and coil voltages, all sharing common mounting and termination standards for interchangeability within ISO-compliant systems.

Relay Automotive Replacement Considerations

Compatible substitutes include other ISO-sized automotive relays with SPDT contacts and 12VDC coils, such as the A2F1CSQ12VDC1.6. Ensure the replacement maintains the same quick connect pin dimensions and chassis mounting footprint to guarantee physical compatibility.
