A3F1ASP12VDC2

Relay Automotive Overview

The A3F1ASP12VDC2 is a sealed automotive relay from the CIT A3 series, designed for high-current switching applications. It features a 12VDC coil with a standard current draw of 150 mA and consumes 1.8 W of power. The unit utilizes an SPST-NO (Single Pole Single Throw Normally Open) contact arrangement, designated as configuration 1A in official documentation. It supports a heavy-duty switching capacity of up to 80A at 14VDC, ensuring robust performance in demanding environments. The relay is RoHS compliant and certified under QS-9000 and ISO-9002 standards.

Relay Automotive Feature Summary

• Sealed construction suitable for harsh automotive environments
• High switching capacity supporting up to 80A loads
• Dual mounting options including PCB pin and chassis flange configurations
• Compliant with QS-9000 and ISO-9002 manufacturing certifications

Relay Automotive Applications

• Automotive lamp accessories
• High-current circuit protection systems
• Vehicle electrical load management
• Industrial control panels requiring sealed relays

Relay Automotive Procurement Notes

Verify the specific suffix 'P' against the manufacturer's latest datasheet to confirm the exact termination style and mounting configuration, as variations exist within the A3 series. Ensure the application voltage aligns with the 12VDC coil rating and that the load current does not exceed the 80A heavy-duty limit. Confirm RoHS compliance requirements if applicable to your supply chain standards.

Relay Automotive Selection Notes

Select this model when a sealed, high-amperage relay is required for automotive or industrial use. The SPST-NO configuration is ideal for simple on/off control of high-power loads. Consider the physical dimensions and mounting type (PCB vs. Chassis) to ensure mechanical compatibility with the target assembly. Verify thermal management needs given the 1.8W coil power dissipation.

Relay Automotive Part Context

This component belongs to the CIT A3 series of large switching capacity relays. The series is characterized by its ability to handle currents up to 80A and its versatility in mounting styles. The A3 series is widely used in automotive applications due to its durability and certification standards. This specific part number denotes a 12VDC coil variant with a normally open contact.

Relay Automotive Replacement Considerations

Cross-reference with other A3 series variants such as A3F1ASQ12VDC2R or A3F1CCQ24VDC1 only if coil voltage and contact configuration match exactly. Verify that substitute parts maintain the same 80A heavy-duty rating and sealed construction to ensure equivalent performance in automotive environments.
