A3F1CSP12VDC2D

Relay Automotive Overview

The A3F1CSP12VDC2D is a non-latching automotive relay manufactured by CIT Relay and Switch. It features a SPDT (Form C) contact arrangement with a standard current rating of 60A at 14VDC and a heavy-duty rating of 80A at 14VDC. The coil operates at 12VDC with a current consumption of 150 mA. Key electrical parameters include a maximum switching power of 1120W, a maximum switching voltage of 75VDC, and an initial contact resistance of less than 30 milliohms. The unit utilizes AgSnO2 In2O3 contact material.

Relay Automotive Feature Summary

• High switching capacity supporting up to 80A in heavy-duty configurations
• Dual mounting options including PCB pins and quick connect terminals
• RoHS compliant construction suitable for automotive applications

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• General purpose high-current switching

Relay Automotive Procurement Notes

Verify the specific contact configuration matches the required circuit design, as the model indicates a single pole double throw arrangement. Confirm that the 12VDC coil voltage aligns with the system supply. Ensure the application does not exceed the 80A heavy-duty limit or the 75VDC maximum switching voltage specified in the official documentation.

Relay Automotive Selection Notes

Select this component when a robust SPDT relay is needed for automotive environments requiring high current handling. The availability of both PCB pin and quick connect mounting provides flexibility for different assembly requirements. Consider the 150mA coil current for power budget calculations and verify space constraints against the 28.5 x 28.5 mm footprint.

Relay Automotive Part Context

This part belongs to the CIT A3 series of automotive relays, which are designed for high-capacity general-purpose switching. The series is characterized by large switching capacities and compliance with ISO-9002 and QS-9000 manufacturing standards. It serves as a reliable solution for demanding automotive and industrial applications requiring durable contact performance.

Relay Automotive Replacement Considerations

Publicly confirmed substitute part numbers for this specific model are not available in the provided documentation. Cross-referencing requires matching the SPDT form, 12VDC coil, and 80A contact rating with alternative manufacturers' datasheets.
